[Qemu-devel] [PATCH v2 00/11] aspeed: misc fixes and enhancements (SMC)

[Cédric Le Goater]

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
