EFI applications like GRUB issue ANSI sequences for setting colors
and for positioning. So if the EFI subsystem is enabled, we should
also enable ANSI control sequences by default.

We have almost all pieces needed to support RISC-V UEFI binaries in place already.
The only missing piece are ELF relocations for runtime code and
data.
This patch adds respective support in the linker script and the runtime
relocation code. It also allows users to enable the EFI_LOADER configuration
switch on RISC-V platforms.

config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
based on a list of enabled options. Moving HAVE_BLOCK_DEVICE to
Kconfig allows us to drastically shrink the logic in
config_fallbacks.h

config_fallback.h has some logic that checks a variety of options
and selects LIB_UUID if it hasn't already been selected. This

We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
always expects that the bitness of the definitions it uses is identical to
the execution.
The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
way around, so it allows for different bitness of EFI definitions and U-Boot
environment.
This patch explicitly requests via Kconfig that efi_loader can only be enabled
if the bitness is identical. Because we can run efi_loader on x86_64 without
EFI stub enabled, it also ensures that this case propagates the correct ABI
constraints.

Enable this so that EFI applications (notably grub) can be run under U-Boot
on x86 platforms.
At present the 'hello world' EFI application is not supported for the
qemu-x86_efi_payload64 board. That board builds a payload consisting of a
64-bit header and a 32-bit U-Boot, which is incompatible with the way the
EFI loader builds its EFI application. The following error is obtained:
x86_64-linux-ld.bfd: i386 architecture of input file
`lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output
This could be corrected with additional Makefile rules. For now, this
feature is disabled for that board.

Assuming it is (ARM64 || ARM), remove the redundancy.
Unlike Linux, CONFIG_ARM includes CONFIG_ARM64 in U-Boot.

Some hardware that is supported by U-Boot can not handle DMA above 32bits.
For these systems, we need to come up with a way to expose the disk interface
in a safe way.
This patch implements EFI specific bounce buffers. For non-EFI cases, this
apparently was no issue so far, since we can just define our environment
variables conveniently.

support, hook them up in Makefiles and KConfigs so that we can build.
