[PATCH linux dev4.7 v2 0/9] aspeed-smc: add support for AST2500 and DMA transfers

[Cédric Le Goater]

Hello,

This patchset adds to the current aspeed SMC driver the register
settings enabling support for the AST2500. Some initial work is done
on the segment registers to provide a better configuration of the
mapping windows on the flash modules but this area clearly needs more
work to be solid.

Also, a first version of DMA read/write is provided. But the speed
results are not very satisfying so they are disabled by default. You

Thanks,

C.

Changes since v1:

 - included a first revert of the current driver
 - merged all the difference in one patch to be sent to mainline
 - added a pinctrl fix for the witherspoon.
