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
expect.
Fix this by ensuring the state is as expected by explicitly
setting that state.

Rasmus Villemoes <ravi@prevas.dk> says:
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.

This also adds a test of the -a flag, which was previously missing,

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

RFC 3447 says that Typical salt length are either 0 or the length
of the output of the digest algorithm, RFC 4055 also recommends
hash value length as the salt length. Moreover, By convention,
most of the signing infrastructures/libraries use the length of
the digest algorithm (such as google cloud kms:
https://cloud.google.com/kms/docs/algorithms).
If the salt-length parameter is not set, openssl default to the
maximum allowed value, which is a openssl 'specificity', so this
works well for local signing, but restricts compatibility with
other engines (e.g pkcs11/libkmsp11):
```
returning 0x71 from C_SignInit due to status INVALID_ARGUMENT:
at rsassa_pss.cc:53: expected salt length for key XX is 32,
but 478 was supplied in the parameters
Could not obtain signature: error:41000070:PKCS#11 module::Mechanism invalid
```
To improve compatibility, we set the default RSA-PSS salt-length
value to the conventional one. A further improvement could consist
in making it configurable as signature FIT node attribute.
