[U-Boot] howto spi nand

[Dr. Matthias Schöpfer]

Hi!

I have a bsp with a patched u-boot Version 1.1.4. The board has nor and
nand chip, both via spi. I have been able to access nor, but struggle
with the spi nand. I have admittedly not much experience with nand
device drivers and u-boot in that matter, but some understanding of
linux kernel. I also have a functioning linux kernel driver for the spi
nand.

My question: Since the internal structure of u-boot has changed
significantly from 1.1.4 to today, what would be the best way to
approach this. I read some mails on the mailing list from 2015 where it
was discussed to support spi nand like spi nor within sf functionality.
Can someone point to a spi nand driver implementation or tell me, what
the driver would have to look like?!

Thanks and Regards,

  Matthias
