Hello,
This series adds a couple of cleanups and two main features to the
Aspeed machines :
- a 'mmio-exec' property to boot directly from a memory region alias
of the FMC flash module using MMIO execution. This is not activated
by default because boot time needs to be improved on recent
firmwares.
- support for DMA to access the flash modules. Our primary need is
the checksum calculation which is used to evaluate the best clock
settings for reads.
Thanks,
C.
