53a1eb994a arm: dts: k3-am65-iot2050: Fix boot
Since commit 9e644284ab ("dm: core: Report bootph-pre-ram/sram node
as pre-reloc after relocation") A53 u-boot proper is broken. This is
because nodes marked as 'bootph-pre-ram' are not available at u-boot
proper before relocation.

To fix this we mark all nodes in u-boot.dtsi as 'bootph-all'.

538b97dd5d spi: mtk_spim: prevent global pll clock override
With commit 793e623011 ("spi: mtk_spim: get spi clk rate only once") a
new system to calculate the SPI clocks has been added.

Unfortunately, the do_div macro overrides the global priv->pll_clk_rate
field. This will cause to have a reduced clock rate on each subsequent
SPI call.

20535a3369 Makefile: make u-boot-initial-env target depend explicitly on scripts_basic
We're seeing sporadic errors like

  ENVC    include/generated/env.txt
  HOSTCC  scripts/basic/fixdep
  ENVP    include/generated/env.in
  ENVT    include/generated/environment.h
  HOSTCC  tools/printinitialenv
/bin/sh: 1: scripts/basic/fixdep: not found
make[1]: *** [scripts/Makefile.host:95: tools/printinitialenv] Error 127
make[1]: *** Deleting file 'tools/printinitialenv'
make: *** [Makefile:2446: u-boot-initial-env] Error 2
make: *** Waiting for unfinished jobs....

where sometimes the "fixdep: not found" is instead "fixdep: Permission
denied" and the Error 127 becomes 126.

This smells like a race condition, and indeed it is: Currently,
u-boot-initial-env is a prerequisite of the envtools target, which
also lists scripts_basic as a prerequisite:

envtools: u-boot-initial-env scripts_basic $(version_h) $(timestamp_h) tools/version.h
	$(Q)$(MAKE) $(build)=tools/env

However, the u-boot-initial-env rule involves building the
printinitialenv helper, which in turn is built using an if_changed_dep
rule. That means we must ensure scripts/basic/fixdep is built and
ready before trying to build printinitialenv, i.e. the
u-boot-initial-env rule itself must depend on the phony scripts_basic
target.

0501c997a0 board: xen: introduce virtio-blk support
Added new xenguest_arm64_virtio_defconfig which
enables support for virtio-blk using various types
of transport like virtio-pci, vrtio-mmio. Currently
supported: up to 2 PCI host bridges and 10 MMIO devices.
Note: DT parsing code was partly taken from pci-uclass.c
Limitation: All memory regions should be
below 4GB address space.

357f4fb0bd board: synquacer: set actual gd->ram_top and gd->ram_size
Current gd->ram_size and gd->ram_top reflect only the
first DRAM bank even if the SynQuacer Developerbox could
have up to three DRAM banks.
With the commit 06d514d77c ("lmb: consider EFI memory map"),
the first DRAM bank indicates <4GB address, so whole >4GB memory
is marked as EFI_BOOT_SERVICES_DATA and it results that
U-Boot can not access >4GB memory.

Since 64-bits DRAM address is fully available on the SynQuacer
Developerbox, let's set the installed DIMM information to
gd->ram_top and gd->ram_size.

2d307fb9ed input: avoid NULL dereference
Before using the result of env_get("stdin") we must check if it is NULL.

Avoid #if. This resolves the -Wunused-but-set-variable issue and we don't
need a dummy assignment in the else branch. Anyway this warning is
disabled in the Makefile.

For sake of readability use an early return after the configuration check.

Checking CONFIG_SPL_BUILD is incorrect as env_get() is only defined if
CONFIG_$(SPL_TPL)ENV_SUPPORT=y.

4860ee9b09 mkimage: allow internalization of data-position
Make it possible for data that was externalized using a static external
position (-p) to be internalized. Enables the ability to convert
existing FIT images built with -p to be converted to a FIT image where the
data is internal, to be converted to a FIT image where the data is
external relative to the end of the FIT (-E) or change the initial
static external position to a different static external position (-p).

Removing the original external-data-related properties ensures that
they're not present after conversion. Without this, they would still be
present in the resulting FIT even if the FIT has been, for example,
internalized.

be98a786b6 Merge branch '2023-10-10-blk-sandbox-support-binding-a-device-with-a-given-logical-block-size'
To quote the author:
At present on Sandbox when binding to a host backing file, the host
block device is created with a hard-coded 512 bytes block size.

Such assumption works for most cases, but for situation that with a raw
image file dump from a pre-formatted GPT partitioned disk image from a
4KiB block size device, when binding this file to a host device and mapping
this device to a blkmap, "blkmap" command like "blkmap part" won't work
correctly, due to block size mismatch during parsing the partition table.

This series updates Sandbox block driver, as well as the blkmap driver,
to get rid of the hard-coded 512 bytes block size assumption.

This series is available at u-boot-x86/blk for testing.

6826c432e3 spl: Jump to image at end of board_init_r
spl_board_prepare_for_boot() is not called before jumping/invoking atf,
optee, opensbi or linux images.

Jump to image at the end of board_init_r() to fix this.

17deab0edd arm: mach-k3: common: fix compile warnings with PHYS_64BIT on 32bit
Use uintptr_t instead of phys_addr_t where appropriate, so passing the
addresses to writel() doesn't result in compile warnings when PHYS_64BIT
is set for 32bit builds (which is actually a useful configuration, as
the K3 SoC family boots from an R5 SPL, which may pass bank information
based on gd->bd->bi_dram to fdt_fixup_memory_banks() etc., so PHYS_64BIT
is needed for fixing up the upper bank).

edb5824be1 lmb: remove overlapping region with next range
In case of new memory range to be added is coalesced
with any already added non last lmb region.

And there is possibility that, then region in which new memory
range added is not adjacent to next region. But have some
sections are overlapping.

So along with adjacency check with next lmb region,
check for overlap should be done.

In case overlap  is found, adjust and merge these two lmb
region into one.

4f9c7a9f54 exynos: Cleanup exynos_init
- None of the callers perform error checking and based on the non-empty
  versions of this function, there's no checking to be done, so make
  this a void.
- Add a default weak version of the function.
- Remove the empty versions of exynos_init now that we have a weak
  version.

db7516b635 board: Remove essentially empty board files and Makefiles
As part of reviewing a new platform, Daniel Schwierzeck noted that we
can have an empty Makefile in the board directory and don't need an
empty board.c file as well.  Further with further cleanup in the
Makefile we can now omit the Makefile entirely. Remove a number of now
unnecessary board.c and Makefiles.

521ca0fa78 Makefile: Allow for board directories to not have a Makefile
It is entirely possible at this point to have platforms in U-Boot that
do not have board-specific C code (just Kconfig or environment) and so
make it optional to have to descend in to and then build in the board
directory.
