Some config symbols are found in *almost* every _defconfig file for
Allwinner boards, because those options are actually a platform choice,
and not a per-board decision.
Some of these options are older, some have recently been added.
Move those options to be set for all Allwinner boards in their
respective Kconfig files.
The rationales are as follows:
- NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of
address space only, starting at 1 GB. So it's always one bank.
- SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC
accesses, we don't care about filesystems or partitions in there, so
there is no need to define those symbols at all.
- USE_PREBOOT: We start USB early when a keyboard is configured, using the
preboot env variable, so we need to set this variable.
- SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this
symbol to be set (according to 8d8ee47e03).
- SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa5,
specifying this reduces the latency of the USB keyboard handling, so
this was formerly enabled in config headers for all Allwinner boards.

The signature 0x55 0xAA in bytes 510 and 511 of the first sector can either
indicate a DOS partition table of the first sector of a FAT file system.
The current code tries to check if the partition table is valid by looking
at the boot indicator of the partition entries. But first of all it does
not count from 0 to 3 but only from 0 to 2. And second it misses to
increment the pointer for the partition entry.
If it is a FAT file system can be discovered by looking for the text 'FAT'
at offset 0x36 or 'FAT32' at offset 0x52. In a DOS PBR there are no
partition entries, so those bytes are undefined. Don't require the byte at
offset 0x1BE to differ from 0x00 and 0x80.
With the patch the logic is changed as follows:
If the partition table has either an invalid boot flag for any partition or
has no partition at all, check if the first sector is a DOS PBR by looking
at the FAT* signature.

Currently EFI_GUID() is used both as an anonymous constant and as an

In commit e163a931af ("cmd: gpt: backup boot code before writing MBR")
there was added the procedure for storing old boot code when doing "gpt

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

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
