This updates the barebox NAND layer and parts of the mtd layer to
Linux-5.9.
This patch is huge, but the barebox NAND layer is so far away from the
Linux NAND layer that a step by step update would have taken ages.
Unlike Linux barebox has functions to mark a block as good. This feature
has been preserved. Also barebox used to make NAND write support
optional, this feature is lost during the update for the sake of better
compatibility to the Linux NAND layer.
This patch has been tested:
- GPMI aka nand_mxs on i.MX6
- nand_imx on i.MX25
- nand_omap_gpmc on AM335x
- atmel_nand on Atmel sama5d3
- nand_denali on SoCFPGA
Currently untested:
- nand_orion
- nand_mrvl_nfc
- nand_s3c24xx
The nand_denali driver is tested with the update of that driver to
Linux-5.9 following in the next patch.
I could only test the drivers with the NAND chips found on my boards, so
there's still enough room for regressions, especially given that the
NAND drivers themselves are mostly not updated. With the NAND layer
being up-to-date with Linux it should hopefully be easy to update
drivers to their Linux counterpart as well if necessary.

This file originates in Linux. Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.
This commit was generated by the following commands:
find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
git mv include/sizes.h include/linux/

This updates the NAND stuff to Linux-3.11-rc1. It is synchronized
as best as we can get:
- locks removed
- The splitting in different files we had to better support different
features has been dropped. Instead this is now done mostly with the
use of __maybe_unused
Some barebox adjustments are forward ported, like:
- Allow partial page writes
- Optionally allow to erase bad blocks
- check for all_ff before writing a page

Some of the newer MLC devices have a 6-byte ID sequence in which
several field definitions differ from older chips in a manner that is
not backward compatible.
This method is already used in the Linux Kernel.
