- usb: tcpm: fix inverted poll condition in tcpm_pd_transmit()
|
|
The read_poll_timeout() macro breaks out of its loop when the condition
evaluates to true. The current code uses "!tx_complete" as the
condition, which means it exits immediately when tx_complete is false
(i.e., transmission has NOT completed yet), rather than waiting for
completion.
Fix the condition to "tx_complete" so that the poll loop waits until
the TCPC signals transmission success/failure/discard before
proceeding.
Without this fix, tcpm_pd_transmit() returns before the TCPC has
finished transmitting, causing the PD state machine to proceed with
stale tx_status values.

This patch set contains a collection of small fixes and cleanups for the
"full" FIT loader that can be used for the SPL. The main beneficiary is
the falcon boot flow, but the same loader can be used also for U-Boot
proper.
Patch 1 was part of another set, but I decided to put it here for a
better separation between plumbing (here) and new features (there). I
kept the Reviewed-by tag collected from Simon in that occasion.
Patch 6 introduces a new unit test covering most of the code that is
being cleaned up.
The set was tested on a i.MX93 FRDM, both with and without signature and
to boot both U-Boot proper and the Linux kernel directly (i.e., falcon
boot).

U-Boot proper expects its FDT to be right after its binary image; the
"full" FIT image loader thus adopts an hack to relocate it, ignoring
the specified load address.
Rework the current form of the hack to:
- support the 'sandbox' environment with a sysmem-aware memcpy;
- use the ALIGN() macro instead of raw alignment logic;
- align the FDT to 8-byte boundary as per FDT specifications;
- fix the debug print (which was reporting the source address for the
relocation instead of the destination one).

As part of the resync to dtc version v1.7.2-35-g52f07dcca47c from the
Linux Kernel, we missed updating the fdt_check_full function because it
exists in its own file in upstream dtc and the kernel doesn't import it,
as reported by Anton Ivanov. This short series brings in the upstream
fdt_check.c file and then implements our size-saving option, but in the
modern way.

The current upstream method of having a function omit various tests is

In the upstream project, the function fdt_check_full has been moved from
fdt_ro.c to its own file, fdt_check.c. This file is not included in the
Linux kernel copy and so has not been synced over. As we do need and use
the fdt_check_full function, bring that file over as of the current
upstream we are synced to. Remove our copy of this function from
fdt_ro.c and add fdt_check.o and 1-liner fdt_check.c where needed. Note
that for now, this will increase size in some cases as upstream does not
have a size reduction method here.

For a compressed kernel_noload image, bootm_load_os() allocates a

kernel compresses by no more than a factor of four. It then passes
CONFIG_SYS_BOOTM_LEN, rather than the size of that buffer, to
image_decomp() as the output limit. The decompressors honour the limit
they are given, so a kernel that decompresses to more than four times
its compressed size is written past the end of the allocated buffer and

Pass the allocation size to image_decomp() and handle_decomp_error() so

set_one_region()"
Casey Connolly <[email protected]> says:
Currently trying to unmap a region results in slow and largely broken
behaviour as we unnecessarily split blocks and manually set thousands of
individual 4k pages instead of higher level blocks.
This series fixes the behaviour of set_one_region() so that it works
properly when called to unmap regions. See patch 4 for details.
Patches 1 & 2 improve the existing debug functionality, the pagetable
dumper will now print most explicitly unmapped regions (since they still
have their PA intact), as well as adding a new function which does a
very basic software TLB lookup to help with debugging.
Patch 3 de-duplicates some code by moving the loop that always surrounds
set_one_region() calls into its own function, this also helps with
readability in the calling functions.
Link: https://lore.kernel.org/r/[email protected]
|

As more platforms start ensuring they explicitly unmap reserved-memory
regions a few issues have appeared with how the existing dynamic mapping
code works. Fix these and get a small optimisation as well.
1. Teach pte_type() to actually respect the PTE_TYPE_VALID bit
2. Don't walk the TLB a second time if we call mmu_change_region_attr()
with PTE_TYPE_FAULT (since it would just be a slow nop)
3. Fix how set_one_region() decides to split blocks.
Today set_one_region() will always split blocks until it reaches the
smallest granule size (4k) and then update all of these pages. This
appears to be due to a big in how is_aligned() is implemented, since
it only evaluates to true if addr and size are both multiples of the
current granule size, so a mapping aligned to 2M which is 4M in size
will cleanly result in 2 blocks being set, but a mapping aligned to
2M which is 4M + 8k in size will result in blocks being split and 1026
individual pages being set.
While for the address it is correct to enforce that it is aligned to
the current granule size, we only need to check if the region size is
greater than the current granule size. This allows us to simplify our
second example above to only 4 entries being updated (assuming no blocks
have to be split) since we only need to update 2 blocks to map the first
4M, drastically improving the best-case performance.
In the case where the address is 4k aligned rather than 2M aligned we
will still be restricted to mapping 4k pages until we reach 2M alignment
where we could then map a larger 2M granule which previously would never
happen.

When a region is explicitly unmapped (like with

Implement a super basic software TLB walk which can look up a single

allocated buffer"
Aristo Chen <[email protected]> says:
For a compressed kernel_noload image, bootm_load_os() allocates a
decompression buffer of ALIGN(image_len * 4, SZ_1M) and then passes
CONFIG_SYS_BOOTM_LEN (typically 128 MiB on arm64) to image_decomp() as
the output limit. The decompressors honour whatever limit they are
given, so a kernel that decompresses to more than four times its
compressed size runs past the end of the allocated buffer and silently
corrupts adjacent memory.
A 4x compression ratio is at the edge of what modern compressors
(zstd, xz) achieve on real kernels, and is trivially exceeded by
crafted, highly compressible payloads, so this is reachable both
accidentally and intentionally. The overflow can land on already-loaded
boot artefacts (FDT, ramdisk, loadables), U-Boot's own data, or
memory-mapped device registers; the existing post-decompression overlap
check in bootm_load_os() only catches overlap with the FIT itself.
Patch 1 plumbs the actual allocation size through to image_decomp() and
handle_decomp_error() via a single decomp_len variable, so
decompression stops at the buffer boundary and fails cleanly when the
image is too large. The non-noload code path is unchanged and continues
to use CONFIG_SYS_BOOTM_LEN. A clarifying note is printed when the
failure is gated by the per-image buffer, so the generic
"increase CONFIG_SYS_BOOTM_LEN" advice does not mislead.
Patch 2 raises the noload-decompression headroom from 4x to 8x. The 4x
factor is at the edge of what zstd and xz achieve on real kernels, so
well-compressed vendor kernels can fail to boot at runtime once the
bound is enforced. 8x covers them comfortably while remaining bounded.
Patch 3 adds two sandbox py-tests against the per-image buffer at the
final 8x value: one that exceeds the buffer and must be rejected, and
one that matches the buffer exactly and must succeed (guarding the
boundary).
Tested on sandbox: both new tests pass; the existing
test_fit_compressed_images_load (which covers the load-address path)
and the other tests in test/py/tests/test_fit.py continue to pass.

Add sandbox tests that exercise the per-image decompression buffer that
bootm_load_os() allocates for a compressed kernel_noload image
(ALIGN(image_len * 8, SZ_1M)).
The overflow test builds a FIT whose decompressed size far exceeds the
per-image buffer and asserts that 'bootm loados' rejects it with a
decompression error rather than overflowing.
The boundary test builds a FIT whose decompressed size equals the
per-image buffer exactly and asserts that 'bootm loados' succeeds,
guarding against an off-by-one rejection at the buffer limit.

I didn't find an clean way to fix the "don't use #ifdef" warning as we
need to define the gpio_bank for the SPL build only.
For the CamelCase warnings, the incriminated attributes represent
timings, so IMHO, it is more readable with CamelCase.
Set myself as OMAP4 maintainer.

This include file isn't used since the omap4 support has been dropped.
Since this support is about to be reintroduced, this file is going to be
used again. The upcoming support is minimal and doesn't include network,
therefore leaving PXE and DHCP in the BOOT_TARGET_DEVICES list would lead
to build errors.
Remove PXE and DHCP from the list of BOOT_TARGET_DEVICES.
Remove the LEGACY_MMC macros and the findfdt script that looks for
no-longer supported boards.
Remove the empty #ifdef XPL_BUILD

The clock controller driven by this driver exists on other OMAP platforms
than the AM33xx. Yet, it uses functions provided by
arch/arm/mach-omap2/am33xx/clock.c making it unusable by other OMAPs.
Replace am33xx-specific do_{enable/disable}_clocks() with new static
functions implemented locally.
Replace the am33xx-specific clock header with the one shared by all OMAP
platforms.

Lots of clock definitions are common to OMAP3, OMAP4 and OMAP5. So the
same macros are defined both in arch-am33xx/clock.h and in
arch-omap5/clock.h. Upcoming support for OMAP4 will again need the same
macros.
Group these common macro definitions into a common omap_clock header
shared across the OMAP2+ families.

PRM_VC_I2C_CHANNEL_FREQ_KHZ is defined in omap5/clock.h but isn't really
related to clocks.
Since it's only used by mach-omap2/vc.c, move its definition there.

This is a DRAM controller driver for the R-Car X5H and its enablement.
This makes the U-Boot on RSIP usable beyond U-Boot shell running on
Cortex-M33, as the U-Boot on RSIP can now load not only SCP firmware
into the SCP core STCM, but also TFA BL31, OPTEE-OS and U-Boot into DRAM
and start them on the Cortex-A720AE core. This is self-contained and
affects only the R-Car X5H and a bit of R-Car V4H, besides it went
through rounds of testing until now, therefore it is safe to include it
this late in the release cycle. I know this will make rc5 massive, sorry
about that.

Originally, 'make DEVICE_TREE_DEBUG=1' only generated extra output on
the console. But since 6cdd7597a2f ("kbuild: Produce diff between base
DT and U-Boot augmented DT if DEVICE_TREE_DEBUG=1"), that has also
left behind lots of files that clutter the repo and are hard to get
rid of manually.
Make sure that a 'make clean' will remove those files, and add them to
.gitignore.

Bind the DBSC5 DRAM controller driver on boot in board_early_init_r(),
which brings up the DBSC5 DRAM controller and its PHY and which enables
access to DRAM present on this system.
Add default boot command which loads additional bootloader components
from HF and UFS storage into SRAM and DRAM, and starts those components
on SCP and AP core 0. The system is then capable of reaching U-Boot on
the AP core 0. Specifically, the following components are loaded:
- SCP firmware, 384 kiB from HF offset 0x4c0000 to SCP STCM
- TFA BL31, 256 kiB from UFS0 offset 0x5000 * 4 kiB sectors to DRAM 0x8c200000
- TEE, 2 MiB from UFS0 offset 0x5200 * 4 kiB sectors to DRAM 0x8c400000
- U-Boot, 1 MiB from UFS0 offset 0x7200 * 4 kiB sectors to DRAM 0x8c300000
- IPL parameters table is generated at DRAM address 0x8c100000
Enable pstore command support to allow dumping kernel console from
pstore/ramoops, which is convenient for debugging. Use as follows:
=> pstore set 0x80000000 0x10000 0x400 0x8000 0 0 0
=> pstore display console

Add Renesas R-Car Gen5 DBSC5 DRAM controller driver. This driver is currently
capable of bringing LPDDR5X DRAM on Renesas R-Car X5H Ironhide board. Further
boards can be supported by supplying board specific DRAM configuration data
via dbsc5_get_board_data().
The driver reuses parts of previous DBSC5 driver, but due to hardware changes,
can not be fully integrated into existing DBSC and DRAM driver, therefore the
currentl DBSC and DRAM drivers are moved into R8A779G0 V4H specific files, and
the R8A78000 X5H files are added in parallel.
The Gen5 DBSC driver is meant to be used in RSIP context, while the Gen4 DBSC
driver is meant to be used in SPL, therefore the Kconfig conditionals have been
adjusted to match.

Add support for Renesas R-Car Gen5 R8A78000 SoC into RT-VRAM
initialization driver. The changes are only a slight adjustment
to the register programming, therefore reuse the existing RT-VRAM
driver and parametrize those changes using driver data.

Loading EFI parts like a Debian-Installer on Rockchip SoCs creates
interesting results, in that on some boards the Grub bootloader can't
find any partitions on a USB-Stick, or loading a kernel from Grub spews
EHCI fail timeout STS_IAA set
messages before failing and on others the loading something like efivars
from an eMMC creates read errors and making the MMC vanish from U-Boot.
This only affected boards with at least 4GB of RAM.
These boards have at least 256MB of memory placed above the actual 4GB
address space (due to the iomem being in between) and while kernel,
initramfs, dt are generally loaded to predefined addresses, additional
EFI parts (efivars, etc) are likely just loaded "somewhere" and it seems
this always landed in that higher up memory part.
Also in the Linux-kernel peripherals like EMMC, USB, etc already run
with a 32bit dma-mask set.
So far, I've seen this on RK3568 and RK3588, but as the same peripherals
are used on most Rockchip SoCs, it makes sense to limit this on all.
So add ARCH_ROCKCHIP to the default-y list of LMB_LIMIT_DMA_BELOW_RAM_TOP.

Commit bd3f9ee679b4 added FORCE to several if_changed rules whose

Commit bd3f9ee679b4 ("kbuild: Bump the build system to 6.1") adds FORCE
as a prerequisite to the if_changed rules here, but the commands use $^
so FORCE leaks in as a stray operand. The dd in cmd_mkalign_mxs fails
(silently, since its stderr is discarded) and the binary is never
aligned, stat in cmd_mkivt_mxs emits an error and cst receives a bogus
argument.
Use $< and $(real-prereqs) instead, which exclude FORCE.

Commit bd3f9ee679b4 ("kbuild: Bump the build system to 6.1") adds FORCE
as a prerequisite to the u-boot-align.bin rule, but cmd_mkalign_eds
expands $^, so FORCE leaks in as a stray operand. The dd then fails
(silently, since its stderr is discarded) and the following mv never
runs, so u-boot.bin never gains its 4096-byte zero prefix. The mask ROM
enters U-Boot 0x1000 (4KB) into the image and the board never starts,
sitting in BootROM download mode (DnX).
Use $< instead of $^, which excludes FORCE and restores the prefix.
