Hello,
This series adds a couple of cleanups and two main features to the
SMC controller of the Aspeed machines :
- a 'execute-in-place' 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. It also breaks migration compatibility.
- 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.
Changes since v1:
- fixed #ifdef leading underscore
- changed the name of the property from 'mmio-exec' to 'execute-in-place'
- improved changelogs
- introduced a DMA address space for the SMC controller
