Since removing reset_cpu() in mach-snapdragon, all Qualcomm platforms
now depend on CONFIG_SYSRESET and will fail to build without it.
Move the dependency from qcom_defconfig to kconfig so that we use
SYSRESET for all platforms.

Sughosh Ganu <[email protected]> says:
The patch series contains some fixes and improvements in the lmb
code, along with addition of corresponding test cases for the changes
made.
The lmb_reserve() function currently does not check if the requested
reservation would overlap with existing reserved regions. While some
scenarios are being handled, some corner cases still exist. These are
being handled by patch 1, along with adding test cases for these
scenarios.
Patch 2 is handling the case of reserving a new region of memory, but
that region overlaps with an existing region. The current code only
handles one particular scenario, but prints a message for the other
scenario of an encompassing overlap and returns back. The patch
handles the encompassing overlap.
Patch 3 is an improvement whereby we allow coalescing a newly reserved
region with an existing region. The current code exits this check
prematurely.
Patch 4 is removing a now superfluous check for overlapping regions
with flag other than LMB_NONE. This now gets handled at an earlier
point in lmb_reserve().
Patch 5 is clubbing the functionality to check if two regions are
adjacent, or overlap, allowing some code re-use.
Patch 6 is optimising the lmb_alloc() function by having it call
_lmb_alloc_base() directly.

The actual logic to allocate a region of memory is in the
_lmb_alloc_base() function. The lmb_alloc() API function calls
lmb_alloc_base(), which then calls _lmb_alloc_base() to do the
allocation. Instead, call the _lmb_alloc_base() directly from both the
allocation API's, and move the error message to the _lmb_alloc_base().

The functions to check if the two said regions are adjacent or overlap
are pretty similar in nature. Club the functionality into a single
function lmb_regions_check() and return the appropriate return value
to signify this aspect.

U-Boot allows re-use of already reserved memory through the
lmb_reserve() and lmb_alloc_addr() API's. This memory re-use is
allowed only when the flag of the existing reserved region and that of
the requested region is LMB_NONE. A check was put in the
lmb_add_region_flags() in commit 8b8b35a4f5e to handle the scenario
where an already reserved region was re-requested with region flag
other than LMB_NONE -- the function then returns -EEXIST in such a
scenario.
The lmb_reserve() function now does a check for a reservation request
with existing reserved regions, and returns -EEXIST in case of an
overlap but when the flag check fails. Remove this now redundant check
from lmb_add_region_flags().

The lmb_add_region_flags() first checks if the new region to be added
can be coalesced with existing regions. The check stops if the two
regions are adjecent but their flags do not match. However, it is
possible that the newly added region might be adjacent with the next
existing region and with matching flags. Check for this possibility by
not breaking out of the loop.

The lmb_fix_over_lap_regions() function is called if the added region
overlaps with an existing region. The function then fixes the overlap
and removes the redundant region. However, it makes certain
assumptions. One assumption is that the overlap would not encompass
the existing region. Another assumption is that the overlap only
occurs between two regions -- the scenario of the added region
overlapping multiple existing regions is not being handled. Handle
these cases by instead calling lmb_resize_regions(). Also remove the
now superfluous lmb_fix_over_lap_regions().

The logic used in lmb_alloc() takes into consideration the existing
reserved regions, and ensures that the allocated region does not
overlap with any existing allocated regions. The lmb_reserve()
function is not doing any such checks -- the requested region might
overlap with an existing region. This also shows up with
lmb_alloc_addr() as this function ends up calling lmb_reserve().
Add a function which checks if the region requested is overlapping
with an existing reserved region, and allow for the reservation to
happen only if both the regions have LMB_NONE flag, which allows
re-requesting of the region. In any other scenario of an overlap, have
lmb_reserve() return -EEXIST, implying that the requested region is
already reserved.
Add corresponding test cases which check for overlapping reservation
requests made through lmb_reserve() and lmb_alloc_addr(). And while
here, fix some of the comments in the test function being touched.

If we try to enable a gate clock that doesn't exist, we used to just
fail silently. This may make sense for early bringup of some core
peripherals that we know are already enabled, but it only makes
debugging missing clocks more difficult.
Bubble up errors now that qcom_gate_clk_en() can return an error code to
catch any still-missing clocks and make it easier to find missing ones
as more complicated peripherals are enabled.

current release. There is the long overdue BL31 start V4H board code as
well, that should be in the current release to make the V4H White Hawk

enablement to make sure the board always boots. And finally, there are

Most MSM8916 devices shipped without PSCI support. The history is quite
nuanced (a good overview can be found in [1]), but the end result is
that the upstream DTs for this SoC pretend that PSCI exists, and it's
expected that the bootloader handles the case where it doesn't. This is
codified by the de-facto bootloader for MSM8916 devices, lk2nd [2].
So we handle it here by deleting the /psci node if we detect the absence
of PSCI. We need to do this early to ensure sysreset works correctly,
since the PSCI firmware driver is PRE_RELOC and binds the PSCI sysreset
driver.
Additionally, show_psci_version is updated to check that PSCI exists.
Currently this banner outputs "PSCI: 65535.65535" on devices without
PSCI support, which isn't very useful :)

qcom_parse_memory is updated to return a -ENODATA error if the passed
FDT does not contain a /memory node, or that node is incomplete (size=0)
board_fdt_blob_setup first tries to call qcom_parse_memory with the
internal FDT (if present+valid). If that fails, it tries again with the
external FDT (again, if present+valid).
When booting with an internal FDT from upstream, it's likely that this
change results in a slight performance hit, since virtually all upstream
qcom DTs lack a fully specified memory node. The impact should be
negligible, though.
qcom_parse_memory was given a detailed docstring adapted from Caleb's
original commit message that introduced the function.

msm_rng_enable is supposed to skip writing to LFSR_CFG + CONFIG
registers in the PRNG_ block if PRNG_CONFIG_HW_ENABLE is already set.
The logic to test for this was inverted.
Without this fix, the driver was causing SError aborts on my MSM8916
device. Stephan Gerhold suggested this was probably because TZ has
marked this as a protected register, since it would also be using it for
RNG.

This section is required by .dynamic and llvm-objcopy will exit with a

Signed-off-by: Sam Edwards <[email protected]>

EFI applications need to be relocatable. Ordinarily, this is achieved
through a PE-format .reloc section, but since that requires toolchain
tricks to achieve, U-Boot's EFI applications instead embed ELF-flavored
relocation information and use it for self-relocation; thus, the
.dynamic section needs to be preserved.
Before this patch, it was tacked on to the end of .text, but this was
not proper: A .text section is SHT_PROGBITS, while the .dynamic section
is SHT_DYNAMIC. Attempting to combine them like this creates a section
type mismatch. While GNU ld doesn't seem to complain, LLVM's lld
considers this a fatal linking error.
This patch moves .dynamic out to its own section, so that the output ELF
has the correct types. (They're all mashed together when converting to
binary anyway, so this patch causes no change in the final .efi output.)

While the _start label is only intended for use locally to populate the
(hand-written) PE header, the linker script includes ENTRY(_start) which
designates it as the entry point in the output ELF, resulting in linker
warnings under some linkers (e.g. LLVM's lld) due to _start not being a
globally-visible symbol. Since ELF is only an intermediary build
format, and the aforementioned PE header correctly points to _start, the
ENTRY(_start) directive could easily be removed to silence this warning.
However, since some developers who are debugging EFI by analyzing the
intermediary ELF may appreciate having correct entry-point information,
this patch instead promotes the _start labels to global symbols,
silencing the linker warning and making the intermediary ELF reflect the
true entry point.
This patch doesn't affect the final output binaries in any way.
