Boards can skip display interface init using board_video_skip().
If display interface was not initialized (e.g. no ipuv3 framebuffer
registered or IPU clock disabled), booting Linux stops due to the
crash in IPU shutdown function, when accessing IPU registers.
Check IPU clock and skip shutdown if clock is not enabled.

Before reading entire FIT image, add sanity check by testing image

When using ISO partitions with a DMA enabled block device driver
reading the ISO partition leads to unaligned DMA operations:
  CACHE: Misaligned operation at range [bffb7da8, bffb85a8]

Align the buffer to make sure we pass a buffer which works for
DMA operations.

If the kernel is configured to be built with debug symbols, or
has bug tables, comparing files may not work if line numbers
change. This makes comparing object files with these options
harder to do. Let's strip out the debug info and drop the
__bug_table here so that we don't see false positives. There may
be other things to drop later, and it may be architecture
specific, but this works for me with my ARM64 build.

As part of fixing the previously reported issues, it was missed that in
the case of mtdparts_init() we need to make sure that tmp_ep is long
enough to contain PARTITION_MAXLEN and a NULL termination.  Then, to be
sure the buffer is NULL terminated, zero the entire buffer rather than
just ensuring the first character is NULL.

The code in board/spear/common/ is not board-specific but

Since this code really is SoC-specific, this commit moves it to

The overflow calculation was incorrect. Adding the start block of the
partition is not needed because the sectors are already relative to the
beginning of the partition. If you attempted to write a file smaller
than cur_part_info.start blocks on a full partition the old calculation
fails to catch the overflow. This would cause an infinite loop in the
determine_fatent function.

Old, incorrect calculation:

ending sector of new file = start sector + file size (in sectors)
last sector = partition start + total sectors on the partition

Adding the partition start block number is not needed because sectors
are already relative to the start of the partition.

New calculation:

ending sector of new file = start sector + file size (in sectors)
last sector = total sectors on the partition

The linker script for SuperH brings the .ppcenv and .ppcenvr section
of common/env_embedded.o into the .text section. However, the .ppcenv
section is only ever filled in by env_embedded.o when
CONFIG_SYS_USE_PPCENV is defined, but no platforms in mainline U-Boot
use this.

In addition, common/env_embedded.o is not always built (when you use
CONFIG_ENV_IS_NOWHERE for example), which causes the following build
failure:

Fixes:

  LD      u-boot
/home/thomas/sh4aeb-linux-musl/bin/sh4aeb-linux-ld.bfd: cannot find common/env_embedded.o

The SuperH architecture allows to be run in either little or big
endian mode. Some SuperH SoCs get the little vs. big endian decision
through mode pins sampled at reset, so if big endian has been choosen
by HW designers, it cannot be easily changed.

Therefore, it makes sense to allow building U-Boot for SuperH in big
endian mode. To allow this, the only change needed is to adjust the
OUTPUT_FORMAT() in the linker script.
