Why is it not always CFI_HOST_ENDIAN?

The default is CFI_HOST_ENDIAN now. That's probably good enough for almost
everyone, so it shouldn't be necessary to make it configurable.

I just tested a board today (SH proc) that if put in big endian mode
needs CFI_BIG_ENDIAN enabled. The hardware guys didn't swap the
bytes for us this time :-)

heh, ok. But to keep the complexity down for new users, let's hide them all
behind 'CFI Advanced configuration options' choice, and probably stick the
interleave/buswidth optimisation options behind it too.

Done. I created "CFI Advanced configuration options" under CFI, moved the
geometry
selection under it and added the endianness selection under it as well.
So, a new Config.in and cfi_endian.h

Hi,
What do you think of the idea of making the choice
of CFI_LITTLE_ENDIAN, CFI_HOST_ENDIAN,
CFI_BIG_ENDIAN and CFI_LART_ENDIAN configurable so
that different boards can setup the driver via configuring physmap
and not have to touch the code at all (if they don't need to set vpp
and
just want a single device)?

Has anyone actually needed to use anything other than HOST_ENDIAN yet?
