This is monstrously verbose when something goes wrong. It should work by
recording the problem and reporting it (once) at the command level. At
present it sometimes outputs hundreds of lines of CRC mismatches.
For now, just silence it all.

At present these files have an #ifdef covering the whole file. Move the

HAVE_BLOCK_DEVICE is only for SPL, but the partition drivers are needed

There's no reason to require an appropriately sized output parameter
for the string, that's error-prone should the table ever grow an
element with a longer string. We can just return the const char*
pointer directly.
Update the only caller accordingly, and get rid of pointless ifdeffery
in the header so that the compiler always sees a declaration and can
thus do type-checking, whether or not PARTITION_TYPE_GUID is enabled

Below is what happens on R-Car H3ULCB-KF using clean U-Boot

In int-ll64.h, we always use the following typedefs:
typedef unsigned int u32;
typedef unsigned long uintptr_t;
typedef unsigned long long u64;
This does not need to match to the compiler's <inttypes.h>.
Do not include it.
The use of PRI* makes the code super-ugly. You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

When building with -pedantic the current definition of EFI_GUID() causes
an error 'initializer element is not constant'.
Currently EFI_GUID() is used both as an anonymous constant and as an
intializer. A conversion to efi_guid_t is not allowable when using
EFI_GUID() as an initializer. But it is needed when using it as an
anonymous constant.
We should not use EFI_GUID() for anything but an initializer. So let's
introduce a variable where needed and remove the conversion.

In commit e163a931af34 ("cmd: gpt: backup boot code before writing MBR")
there was added the procedure for storing old boot code when doing "gpt
write". But instead of storing just backup code, the whole MBR was
stored, and only specific fields were replaced further, keeping
everything else intact. That's obviously not what we want.
Fix the code to actually store only old boot code and zero out
everything else. This fixes next testing case:
=> mmc write $loadaddr 0x0 0x7b
=> gpt write mmc 1 $partitions
In case when $loadaddr address and further memory contains 0xff, the
board was bricked (ROM-code probably didn't like partition entries that
were clobbered with 0xff). With this patch applied, commands above don't
brick the board.

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.

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 checks that no partitions overlap with the GPT partition
table using the offset of the first LBA usable for that partition.
This works fine, unless you have a partition entry that is further away
than it usually is and you want to create partitions in the gap between the
GPT header and the GPT partition entries, for example to reflash a
bootloader that needs to be set there.
Rework the test to something a bit smarter that checks whether a partition
would overlap with either the GPT header or the partition entries, no
matter where it is on the disk.
Partitions that do not have a start LBA specified will still start at the
first LBA usable set in the GPT header, to avoid weird behaviours.

Some architectures require their SPL loader at a fixed address within
the first 16KB of the disk. To avoid an overlap with the partition
entries of the EFI partition table, the first safe offset (in bytes,
from the start of the device) for the entries can be set through
CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig)
When formatting a device with an EFI partition table, we may need to
leave a gap between the GPT header (always in LBA 1) and the partition
entries. The GPT header already contains a field to specify the
on-disk location, which has so far always been set to LBA 2. With this
change, a configurable offset will be translated into a LBA address
indicating where to put the entries.
Now also allows an override via device-tree using a config-node (see
doc/device-tree-bindings/config.txt for documentation).
Tested (exporting an internal MMC formatted with this) against Linux,
MacOS X and Windows.
