[PATCH 0/2] SPI NOR - force 3byte addressing mode

[Marcin Wojtas <mw@xxxxxxxxxxxx>]

Hi,

This very short patchset introduces optional forcing via DT
3byte addressing mode for accessing the SPI flash, whose
size exceeds 16MiB.

It can be used in case the device does not support
SPI_NOR_4B_OPCODES and helps overcome an issue, when
the Boot ROM cannot handle non-default settings
that could be enabled in the kernel and remain after soft reset.

I'm looking forward to any comments or remarks.

Best regards,
Marcin
