Merge patch series "Make LMB memory map global and persistent"
Sughosh Ganu <sughosh.ganu@linaro.org> says:
This is a follow-up from an earlier RFC series [1] for making the LMB
and EFI memory allocations work together. This is a non-rfc version
with only the LMB part of the patches, for making the LMB memory map
global and persistent.
This is part one of a set of patches which aim to have the LMB and EFI
memory allocations work together. This requires making the LMB memory
map global and persistent, instead of having local, caller specific
maps. This is being done keeping in mind the usage of LMB memory by
platforms where the same memory region can be used to load multiple
different images. What is not allowed is to overwrite memory that has
been allocated by the other module, currently the EFI memory
module. This is being achieved by introducing a new flag,
LMB_NOOVERWRITE, which represents memory which cannot be re-requested
once allocated.
The data structures (alloced lists) required for maintaining the LMB
map are initialised during board init. The LMB module is enabled by
default for the main U-Boot image, while it needs to be enabled for
SPL. This version also uses a stack implementation, as suggested by
Simon Glass to temporarily store the lmb structure instance which is
used during normal operation when running lmb tests. This does away
with the need to run the lmb tests separately.
The tests have been tweaked where needed because of these changes.
The second part of the patches, to be sent subsequently, would work on
having the EFI allocations work with the LMB API's.
1) These patches are on next, as the alist patches have been
applied to that branch.
2) I have tested the boot on the ST DK2 board, but it would be good to
get a T-b/R-b from the ST maintainers.
3) It will be good to test these changes on a PowerPC platform
(ideally an 85xx, as I do not have one).

mach-imx: do not use if_changed more than once per target
doc/develop/makefiles.rst has the following note:
if_changed should not be used more than once per target.
It stores the executed command in a corresponding .cmd
file and multiple calls would result in overwrites and
unwanted results when the target is up to date and only the
tests on changed commands trigger execution of commands.
The mach-imx Makefile does not follow this recommandation, so fix it
by implementing a single command that performs both the cpp_cfg
and imx9_check actions.
This change fixes an issue with "tools/buildman/buildman imx8ulp_evk"
failing every other time [1].

bootstage: Fix unstash of records from SPL
The commit b81e31a1e6c5 ("bootstash: Do not provide a default address
for all") changed a bootstage unstash call to bootstage stash, this
has resulted in bootstage records stashed in SPL no longer get unstaged
in U-Boot proper. Fix this by changing back to a unstage call.

mtd: rawnand: meson: read/write access for boot ROM pages
Boot ROM on Meson needs some pages to be read/written in a special mode:
384 byte ECC mode (so called "short" by Amlogic) and with scrambling
enabled. Such pages are located on the chip in the following way (for
example):
pX is page number "X". "^" means "special" page used by boot ROM - e.g.
every 2nd page in the range of [0, 7]. Step (2 here) and last page in
range is read from the device tree.

mtd: rawnand: nand_base: support for 'NAND_IS_BOOT_MEDIUM' flag
Based on Linux kernel:
commit f922bd798bb9 ("mtd: rawnand: add an option to specify NAND chip as a boot device")
Allow to define a NAND chip as a boot device. This can be helpful
for the selection of the ECC algorithm and strength in case the boot
ROM supports only a subset of controller provided options.
mmc: fix signed vs unsigned compare in read check in _spl_load()
Fix signed vs unsigned compare in read check in _spl_load()
Issue: when info->read() returns a negative value because of an error,
the comparison of 'read' (signed) with 'sizeof(*header)'
(unsigned silently converts the negative value into a very
large unsigned value and the check on the error condition
always return false, i.e. the error is not detected
Symptoms: if spl_load_image_fat() is unable to find the file 'uImage',
the SPL phase of the boot process just hangs after displaying
the following line:
Trying to boot from MMC1
Fix: cast 'sizeof(*header)' to int so the compare is now between
signed types

gpio: Add G7 Aspeed gpio controller driver
In the 7th generation of the SoC from Aspeed, the control logic of the
GPIO controller has been updated to support per-pin control. Each pin now
has its own 32-bit register, allowing for individual control of the pin’s
value, direction, interrupt type, and other settings.

lib: move phdr increment to for loop heading
Shifting this pointer in the loop will be more logical when working
with the code later, because you can see at a glance what exactly
changes at each iteration. Moreover, the code remains equivalent
because this variable is not used after the loop.
