Merge tag 'spi-nor/for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into mtd/next
SPI NOR introduces byte swap support for 8D-8D-8D mode and a user for
it: macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary
when configured in Octal DTR mode. For such cases the byte order is
propagated through SPI MEM to the SPI controllers so that the controllers
swap the bytes back at runtime. This avoids breaking the boot sequence
because of the endianness problems that appear when the bootloaders use
1-1-1 and the kernel uses 8D-8D-8D with byte swap support. Along with the
SPI MEM byte swap support we queue a patch for the SPI MXIC controller
that swaps the bytes back at runtime.
