U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.

The current code, if there's both an eMMC and an MMC slot available on the
board, will swap the MMC indices based on whether we booted from the eMMC
or the MMC. This way, the MMC we're supposed to boot on will always have
the index 0.
However, this causes various issues, for example when using other
components that base their behaviour on the MMC index, such as fastboot.
Let's remove that hack, and take the opposite approach. The MMC will always
have the same index, but the bootcmd will pick the same device than the one
we booted from. This is done through the introduction of the mmc_bootdev
environment variable that will be filled by the board code based on the
boot device informations we can get from the SoC.
In order to not introduce regressions, we also need to adjust the fastboot
MMC device and the environment device in order to set it to the eMMC, over
the MMC, like it used to be the case.

Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load
and boot. This is added as a sub-command of bootefi.
The idea is that the distro bootcmd would first try loading a payload
via the bootmgr, and then if that fails (ie. first boot or corrupted
EFI variables) it would fallback to loading bootaa64.efi. (Which
would then load fallback.efi which would look for \EFI\*\boot.csv and
populate BootOrder and BootXXXX based on what it found.)

Add EFI variable support, mapping to u-boot environment variables.
Variables are pretty important for setting up boot order, among other
things. If the board supports saveenv, then it will be called in
ExitBootServices() to persist variables set by the efi payload. (For
example, fallback.efi configuring BootOrder and BootXXXX load-option
variables.)
Variables are *not* currently exposed at runtime, post ExitBootServices.
On boards without a dedicated device for storage, which the loaded OS
is not trying to also use, this is rather tricky. One idea, at least
for boards that can persist RAM across reboot, is to keep a "journal"
of modified variables in RAM, and then turn halt into a reboot into
u-boot, plus store variables, plus halt. Whatever the solution, it
likely involves some per-board support.
Mapping between EFI variables and u-boot variables:
efi_$guid_$varname = {attributes}(type)value
For example:
efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_OsIndicationsSupported=
"{ro,boot,run}(blob)0000000000000000"
efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_BootOrder=
"(blob)00010000"
The attributes are a comma separated list of these possible
attributes:
+ ro - read-only
+ boot - boot-services access
+ run - runtime access
NOTE: with current implementation, no variables are available after
ExitBootServices, and all are persisted (if possible).
If not specified, the attributes default to "{boot}".
The required type is one of:
+ utf8 - raw utf8 string
+ blob - arbitrary length hex string

Instead convert over to use efi_device_path helpers to construct

Also, extract out a helper to plug things in properly to the

fdt_getprop(...) returnes a len with -1 for a non-existing property, but
a memcpy with len -1 isn't a good idea and things went wrong (crash).

Some times later Tom did repair this
with commit 99bb38e2cc

This repairs the crash but the behaviour of the command isn't like
