Since commit ad1ecd2063 ("fdt: Build a U-Boot binary without device
tree"), u-boot-dtb.img is identical to u-boot.img, so SPL can always

Implement support for saving ARM register R4 early during boot using
save_boot_params . Implement support for decoding the stored register
R4 value in spl_boot_device() to obtain boot device from which the
SoC booted. This way, the SPL will always load U-Boot from the same
device from which the SPL itself booted instead of using hard-coded
boot device.
This functionality is useful for example when booting sama5d2-xplained
from SD card, where by default the SPL would try loading the U-Boot
from eMMC and fail. This is because eMMC is on SDHCI0 (BOOT_DEVICE_MMC1),
while SD slot is on SDHCI1 (BOOT_DEVICE_MMC2) and the SPL was hard-wired
to always boot from BOOT_DEVICE_MMC1.

Commit 4f144a4164 "malloc: work around some memalign fragmentation
issues" enhanced memalign() so that it can succeed in more cases where
heap fragmentation is present. However, it did not solve as many cases
as it could. This patch enhances the code to cover more cases.
The alignment code works by allocating more space than the user requests,
then adjusting the returned pointer to achieve alignment. In general, one
must allocate "alignment" bytes more than the user requested in order to
guarantee that alignment is possible. This is what the original code does.
The previous enhancement attempted a second allocation if the padded
allocation failed, and succeeded if that allocation just happened to be
aligned; a fluke that happened often in practice. There are still cases
where this could fail, yet where it is still possible to honor the user's
allocation request. In particular, if the heap contains a free region that
is large enough for the user's request, and for leading padding to ensure
alignment, but has no or little space for any trailing padding. In this
case, we can make a third(!) allocation attempt after calculating exactly
the size of the leading padding required to achieve alignment, which is
the minimal over-allocation needed for the overall memalign() operation to
succeed if the third and second allocations end up at the same location.
This patch isn't checkpatch-clean, since it conforms to the existing
coding style in dlmalloc.c, which is different to the rest of U-Boot.

Per ACPI spec, during ACPI OS initialization, OSPM can determine
that the ACPI hardware registers are owned by SMI (by way of the
SCI_EN bit in the PM1_CNT register), in which case the ACPI OS
issues the ACPI_ENABLE command to the SMI_CMD port. The SCI_EN bit
effectively tracks the ownership of the ACPI hardware registers.
However since U-Boot does not support SMI, we report all 3 fields
in FADT (SMI_CMD, ACPI_ENABLE, ACPI_DISABLE) as zero, by following
the spec who says: these fields are reserved and must be zero on
system that does not support System Management mode.
U-Boot seems to behave in a correct way that the ACPI spec allows,
at least Linux does not complain, but apparently Windows does not
think so. During Windows bring up debugging, it is observed that
even these 3 fields are zero, Windows are still trying to issue SMI
with hardcoded SMI port address and commands, and expecting SCI_EN
to be changed by the firmware. Eventually Windows gives us a BSOD
(Blue Screen of Death) saying ACPI_BIOS_ERROR and refuses to start.
To fix this, turn on the SCI_EN bit by ourselves. With this patch,
now U-Boot can install and boot Windows 8.1/10 successfully with
the help of SeaBIOS using legacy interface (non-UEFI mode).
