This adapts the sama5d3 first stage patch set I sent around a few times
for use on the sama5d2. Unlike the original patch set, we now do the
chainloading in the PBL, so integrators can still use multi-image and
don't have to build barebox more than once.
With the FAT PBL implementation in place, first stages of the OMAP and
SoCFPGA could also be migrated to multi-image.
Much code has been adapted from at91bootstrap v3.8.12. Key changes:
- We detect bootsource automatically, so we don't need to hardcode
which MCI instance to use
- We pass along the bootsource, so it's available to second stage
bootloaders
- We don't reset the SD card, so we can avoid having a complete
SD/MMC core implementation in PBL
- We don't disable the watchdog in first stage. We leave the decision
on how to deal with it to second stage.
There's no defconfig for this yet, it will follow along with a generic
at91_multi_defconfig, when support for the sama5d3 is posted.
Cheers,
