Subject: [PATCH] mtd: spinand: add work-around to prevent bootloader wiping
mtdparts
ASUS makes use of U-Boot's fdt_fixup_mtdparts() function which applies
the partitions defined in U-Boot's mtdparts and mtdids environment
variables to the devicetree passed over to Linux.
The undesired side-effect is that in this way also all additional
properties and child nodes get wiped, preventing NVMEM cells to be
defined for MTD partitions or UBI volumes.
To work-around this issue, add an additional compatible string
'u-boot-dont-touch-spi-nand' which can be used instead of 'spi-nand' in
case the replacement of the MTD partitions by U-Boot should be skipped
alltogether.
In practise this is mostly relevant for SPI-NAND which anyway comes only
with two partitions nowadays: 'Bootloader' and 'UBI_DEV'. Hence this
work-around is applicable for SPI-NAND only. Similar work-arounds for
other MTD devices can be created as well should they actually be needed.
