When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

The get_codeseg32() wants to know if a passed in descriptor has
flag GDT_NOTSYS set (desc & GDT_NOTSYS), not whether desc and
GDT_NOTSYS are not != 0 (desk && GDT_NOTSYS).
This is an obvious typo. Fix it up.

Commit f5a2a93892 ("efi_loader: consistently use efi_uintn_t in boot
services") changed the internal EFI API header without adapting its existing
EFI stub users. Let's adapt the EFI stub as well.

Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.
Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

At present we use a CONFIG option in efi.h to determine whether we are
building the EFI stub or not. This means that the same header cannot be
used for EFI_LOADER support. The CONFIG option will be enabled for the
whole build, even when not building the stub.
Use a different define instead, set up just for the files that make up the
stub.

We want to be able to add other common code to this function. So change the
driver's version to have an underscore before it, just like
_debug_uart_putc(). Define debug_uart_init() to call this version.
Update all drivers to this new method.

Most EFI implementations use 64-bit. Add a way to build U-Boot as a 64-bit
EFI payload. The payload unpacks a (32-bit) U-Boot and starts it. This can
be enabled for x86 boards at present.

It is useful to be able to load U-Boot onto a board even if is it already
running EFI. This can allow access to the U-Boot command interface, flexible
booting options and easier development.
The easiest way to do this is to build U-Boot as a binary blob and have an
EFI stub copy it into RAM. Add support for this feature, targeting 32-bit
initially.
Also add a way to detect when U-Boot has been loaded via a stub. This goes
in common.h since it needs to be widely available so that we avoid redoing
initialisation that should be skipped.

When running as an EFI application, U-Boot must request memory from EFI,
and provide access to the boot services U-Boot needs.
Add library code to perform these tasks. This includes efi_main() which is
the entry point from EFI. U-Boot is built as a shared library.
