This series provides an alternative solution to the previously posted series titled "System Firmware Loader for TI K3 family SoCs" [1] using the existing FS loader driver rather than extending the SPL loader framework like the original patch series. Unlike the original series, it does not support eMMC/SD partition/sector based RAW loading, and it is larger in size.
It is only provided to support the discussion around to the initial series posted as "System Firmware Loader for TI K3 family SoCs" and is not intended to supersede this series, hence it is labeled as "RFC".
The interesting pieces are really in patches 04/11 (extension of FS loader to allow using platform data so one does not have to use either ENV or DTS), and 05/11 which implementes the usage of FS loader, including the required sequence of MMC initialization steps inspired by how SPL does it.
