6fd111bc4e cmd: Drop last reference to CMD_REISERFS
While the code was removed in commit 3766a249a3 ("fs: drop reiserfs")
this reference in the Makefile was missed. Remove it now.

096aa229a9 mach-k3: common_fdt: create a reserved memory node
Some device trees may not have a reserved-memory node. Rather than
exiting early we should create a new reserved-memory node along with
the memory carveout for the firmware we (U-Boot) have placed.

7a765a37b3 tools: add HOSTCFLAGS from openssl pkg-config
HOSTCFLAGS of some tools components (image-host, rsa-sign and
ecdsa-libcrypto) depend on the directory where openssl is installed.
Add them via pkg-config.
This fixes a potential build failure in tools when openssl in installed
in varied directories.

3e73373c37 Merge patch series "xPL-stack cleanup"
Simon Glass <sjg@chromium.org> says:

This series was split from the VBE part H series. It adjusts the logic
for selecting the top of the stack so that it is more consistent across
xPL phases.

ffa98c08e8 spl: Use CONFIG_VAL() to obtain the SPL stack
Now that we have the same option for SPL and TPL, simplify the logic for
determining the initial stack.

Note that this changes behaviour as current SPL_STACK is a fallback for
TPL. However, that was likely unintended and can be handled with Kconfig
defaults if needed.

e7741f1124 tpl: Rename TPL_NEEDS_SEPARATE_STACK to TPL_HAVE_INIT_STACK
The most common word for features that make a platform work is to use
'HAVE_xxx'. Rename this option to match.

Update the help to use the word 'phase' rather than 'stage', since
that is the current terminology. Also clarify that, absent this setting,
the stack pointer generally comes from the value used by U-Boot proper,
rather than SPL.

Move the option just above TPL_STACK which depends on it.

Legacy PCI devices, like qemu's Bochs VGA device, are allowed to have

32-bit prefetchable BARs. Typically prefetchable BARs are 64-bit and
typically the prefetch MMIO window is also 64-bit and placed above
4GiB, as it's the case on qemu sbsa-ref.

Currently the U-Boot code assumes that prefetchable BARs are
64-bit BARs and always tries to assign them into the prefetch
MMIO window.

When a 32-bit BAR is marked as prefetch, but the prefetch area is
not within the first 4GiB of the address space, then downgrade the
BAR and place it in the non-prefetch MMIO window.

For prefetch BARs there's no downside on being placed in non prefetch
MMIO areas, besides the possible slower performance when a driver tries
to map it Write-Combine.

TEST: Fixes pci_auto on QEMU sbsa-ref fails to autoconfigure BAR0.

1a87755ecd serial: stm32: restrict _debug_uart_init() usage
Since commit 948da7773e ("arm: Add new config option ARCH_VERY_EARLY_INIT")
debug_uart_init() is called respectively in crt0.S and crt0_64.S.
That means that _debug_uart_init() is called for all STM32MP platforms
even for those which doesn't support SPL_BUILD.

So restrict _debug_uart_init() execution for platforms which can have
SPL_BUILD enabled (STM32MP1 platform only).

It's more needed to call debug_uart_init() in stm32mp1/cpu.c.

be5523d382 pwm: stm32: add driver to support pwm with timer
Add driver to support pwm on STM32MP1X SoCs. The PWM signal is generated
using a multifuntion timer which provide a pwm feature. Clock rate and
addresses are retrieved from the multifunction timer driver.
