** Booting bootflow 'mmc@2194000.bootdev.part_1' with extlinux
Ignoring unknown command: �D���D��
Boot failed (err=-14)
The reason is because while allocating buffer to read a file from MMC,
alignment of 1 byte is used. Thus, the buffer doesn't work for performing
DMA, and garbage data is read.
While looking at this issue, I also noticed that if no alignment specified
(align=0) then fs_read_alloc() is documented to use the default. But the
default is no alignment. Therefore, other users of fs_read_alloc() which
specify align=0 may be broken as well.
The first patch changes extlinux_read_bootflow() to use proper buffer
alignment for DMA.
The second patch changes the default alignment of fs_read_alloc() to be
DMA-suitable, to fix other potential bugs.
The comment above fs_read_alloc() explains:
@align: Alignment to use for memory allocation (0 for default)
However, in the actual implementation, there is no alignment when @align is
zero.
This current default is probably fine for most cases. But for some block
devices which transfer data via DMA, ARCH_DMA_MINALIGN is needed.
Change the default alignment to ARCH_DMA_MINALIGN.

Usually ARMv8 platforms allow unaligned access for Normal memory. But
some chips might not allow it by default, having SCTLR.A bit set to 1
before U-Boot execution. One such example is Exynos850 SoC. As
allow_unaligned() is not implemented for ARMv8 at the moment, its __weak
implementation is used, which does nothing. That might lead to unaligned
access abort, for example when running EFI selftest. Fix that by
implementing allow_unaligned() for ARMv8.
The issue was found when running EFI selftest on E850-96 board
(Exynos850 based):
=> bootefi selftest $fdtcontroladdr
...
Executing 'HII database protocols'
"Synchronous Abort" handler, esr 0x96000021, far 0xbaac0991
...
resetting ...
Unaligned abort happens in u16_strnlen(), which is called from
efi_hii_sibt_string_ucs2_block_next():
u16_strlen(blk->string_text)
where 'blk' type is struct efi_hii_sibt_string_ucs2_block. Because this
struct is packed, doing "->string_text" makes 'blk' address incremented
by 1 byte, which makes it unaligned. Although allow_unaligned() was
called in efi_init_early() before EFI selftest execution, it wasn't
implemented for ARMv8 CPUs, so data abort happened.

Some of the bootm tests rely on state that is assumed to be
correct but is changed by the tests. This means that running
'ut bootm' twice will result in failures on the second run
as the state left by the first run is not what the tests

Fix this by ensuring the state is as expected by explicitly

Doing bringup of a board, part of my bootstrap logic is in U-Boot. So
when tweaking that logic, I was bitten by a previous completed
bootstrap having left a copy of the environment on the device, which
was imported and thus overrided the new logic.
So I thought, "ok, I'll just make sure to put 'env default -a' as the
first part of the bootstrap logic so I'm not bitten again". Alas, my
logic also relies on certain variables that are set by C code
(e.g. for detecting board variant), and doing 'env default -a' also
eliminates those.
Looking around, the hashtab code already supports a flag that does
exactly what I need, and exposing that is (morally) a one-liner.

It can be useful to set all variables defined in the default
environment to the value they have there, but without removing
variables that are only defined at runtime. This can sort-of be done
today, by using the "env default var1 var2 ..." variant, but that
requires listing all variables defined in the default
environment. It's much more convenient to be able to say
env default -k -a
The -k flag is also meaningful in the other case: If var1 is not
defined in the default environment, but var2 is,
env default var1 var2
would emit a warning about var1 not being in the default env and thus
being deleted. With -k, there's no warning, and var1 is kept as-is.

Running commands such as 'load mmc 2:1 $addr $path' when path does not
exists will print an error twice if the file does not exist, e.g.:
```
Cannot lookup file boot/boot.scr
Failed to load 'boot/boot.scr'
```
(where the first line is printed by btrfs and the second by common fs
code)
Historically other filesystems such as ext4 or fat have not been
printing a message here, so do the same here to avoid duplicate.
The other error messages in this function are also somewhat redundant,
but bring useful diagnostics if they happen somewhere, so have been left
as printf.
Note that if a user wants no message to be printed for optional file
loads, they have to check for file existence first with other commands
