blk_dwrite/blk_derase returns the number of blocks
written/erased. The existing check allowed partial
writes or partial erase to be considered successful.
Fix error handling of blk_dwrite/blk_derase by checking
that return value corresponds to the number of blocks
written/erased.

The variable `pend_tab_total_sz` is calculated using the macro
`LPI_PENDBASE_SZ`, which depends on the global variable `lpi_id_bits`.
However, `lpi_id_bits` is initialized later in the function based on
the GICD_TYPER register. This results in `pend_tab_total_sz` being
calculated with an uninitialized `lpi_id_bits` value (0), This leads
to the LPI pending tables being mapped with an incorrect size.

Replace hardcoded WDOG_BASE_ADDR with driver model based dynamic address
lookup from device tree, allowing reset_cpu() to dynamically locate
watchdog devices from device tree.
This change also enables CONFIG_WDT for relevant boards and ensures the
watchdog nodes are available for driver model usage.
- Remove hardcoded WDOG_BASE_ADDR from hw_watchdog_* functions
- Reimplement reset_cpu() using UCLASS_WDT device iteration
- Add ulp_wdt_expire_now() callback for standard WDT interface
- Pass wdog register pointer to hw_watchdog_set_timeout()
- Enable CONFIG_WDT for boards using ULP watchdog
- Remove wdog3 status = "disabled" overrides from U-Boot device tree
overlays, as the watchdog device needs to be accessible for driver
model based reset functionality.

Caleb Ethridge <[email protected]> says:
This series performs a general cleanup of the default U-boot environment
for sc5xx boards, stemming from the decision to no longer store the
environment in the SPI flash. The environments for each board have been
edited to contain the minimum number of commands needed for all supported
boot modes to avoid confusion, and the default boot command synced to spi
for all boards that support it. The filesystem for the SPI flash has also
been changed from jffs2 to ubifs.
A bug with the Ethernet reset line on the sc594 has been fixed, and the
sc573 has been renamed from the EZKIT to the EZLITE to match the name of the
publically available board. EZKIT was only used internally before release.
Preliminary binman support for sc5xx boards has been removed as it was unused
and full support never added.

On hardware architectures, we need to treat start.o (generated from
start.S) very special due to the constraints of being a program running
on hardware in an unknown state. These objects are treated a little
different than the rest by the linker and linker scripts on various
architectures.
Sandbox is different, and doesn't need to do that. In fact, it can lead
to hard to diagnose problems because of just how subtly different the
treatment is. For example, the comment about LTO in include/event.h
introduced with commit 87a5d1b5d012 ("event: Add basic support for
events") was only a sandbox issue because of the event in start.c and
in turn linking start.o isn't treated the same way as an archive with
all its sections considered.
Correct all of this by removing the "head-" lines for cpu.o and sdl.o
from arch/sandbox/Makefile (and unused cmd_cc_sdl.o lines) and change
arch/sandbox/cpu/Makefile to treating them both with "obj-" and not
"extra-".

This series updates the Resource Management configuration for Toradex
K3-based boards and makes sure the TIFS-specific RM configuration is

For Verdin AM62P, the tifs-rm-cfg.yaml file is refreshed with
k3-resource-partition V12.00.00 so that it stays in sync with the
existing rm-cfg.yaml update for the v11.02.09 and v12.00.00 TIFS

For Verdin AM62, the missing tifs-rm-cfg.yaml file is added. The file
matches the TI AM62x configuration, and rm-cfg.yaml was verified to
remain unchanged when regenerated with the same tool version.
For Aquila AM69, both rm-cfg.yaml and tifs-rm-cfg.yaml are updated to
match the resource allocation changes already present in the TI J784S4
configuration files.
Finally, the Verdin AM62 and Verdin AM62P binman descriptions are

Sync include/ec_commands.h from upstream commit 4f3d17aa34
("skywalker: set SLEEP_TIMEOUT_MS to 50 seconds"). The new file makes
two build assumptions that do not hold for U-Boot.
It hides '<stdint.h>' from __KERNEL__ builds, leaving UINT16_MAX
(used by EC_RES_MAX) undefined for U-Boot; widen the gate to
'!defined(__KERNEL__) || defined(__UBOOT__)'
It gates '<linux/limits.h>' on '#ifdef __KERNEL__'; the matching
'#else' branch defines BIT()/BIT_ULL()/GENMASK()/GENMASK_ULL()
locally, assuming kernel headers provide those macros otherwise.
U-Boot defines __KERNEL__ too but has no <linux/limits.h>. Nest a
'!defined(__UBOOT__)' check around the include so the __UBOOT__ path
stays in the __KERNEL__ branch (no local BIT/GENMASK defines), which
avoids redefinition warnings against U-Boot's linux/bitops.h. Pull
in linux/bitops.h up front for U-Boot so the file's own BIT() and
GENMASK() uses still resolve.
Adapt callers to two interface changes. The 'ec_current_image' enum
tag is now 'ec_image' (EC_IMAGE_* constants unchanged); rename it in
affected files to match. The VBNV-context interface was dropped
upstream, but it still used in lab Chromebooks; keep those constants and
structs in cros_ec.h
Likewise, MEC_EMI_BASE and MEC_EMI_SIZE are a U-Boot-local addition to
ec_commands.h that the upstream sync removes; preserve them in cros_ec.h
next to the VBNV block, and switch the only consumer
(arch/x86/cpu/apollolake/cpu_spl.c) to include cros_ec.h

This patch series fixes firewall exceptions observed on AM62 family of

regions.
Link: https://lore.kernel.org/r/[email protected]
|

Currently the sequence to enable caches for the A53/A72 core on K3
devices looks as follows:
1. Map entire DDR banks
2. Setup page tables (done by mmu_setup)
3. Enable MMU
4. Unmap reserved-memory regions
5. Enable caches
However there is a brief period of execution between #3 and #4 where the
core can issue speculative accesses to the entire DDR space (including
the reserved-memory regions) despite the caches being disabled.
A firewall exception is triggered whenever such speculative access is
made to secure DDR region of TFA or OP-TEE. This patch fixes the issue
by re-ordering the sequence as follows:
1. Map entire DDR banks
2. Setup page tables
3. Unmap reserved-memory regions
4. Enable MMU
5. Enable caches

Currently mmu_setup for ARMv8 performs two functions, first it sets up
the page tables based the memory map provided by the board and then it
enables the MMU.
However for some platforms runtime fixes to the generated page tables
are required before the MMU can be enabled, such as K3 family of SoCs.
Therefore this patch moves the enablement of the MMU out of mmu_setup
and to a standalone mmu_enable function to give more granular control to
the platforms.
Note that no functional changes are intended from this patch.

Add support for building U-Boot for Cortex-M33 RSIP core in Renesas
R-Car Gen5 R8A78000 X5H SoC. The main goal is to start U-Boot on the
Cortex-M33 RSIP core, which initializes the hardware and then starts
the Cortex-M33 SCP and Cortex-A720 cores which run the SCP firmware
and applications software respectively. The SCP is responsible for
platform resource management, and is used to start other CPU cores.
The Cortex-M33 build contains its own r8a78000_ironhide_cm33_defconfig
which configures the build for aarch32 instruction set compatible with
the ARMv8M core. The build also uses -cm33 DT and -u-boot.dtsi which
are derived from their non-CM33 counterparts, and add CM33 specifics.
The arch/arm/mach-renesas/u-boot-rsip.lds is derived from generic
arch/arm/cpu/u-boot.lds with adjustments to cater to the RSIP core,
those are entrypoint before vectors, __data_start/__data_end symbols
for data-only relocation, and placement of BSS into read-write SRAM
area.
