Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sh
This is a DRAM controller driver for the R-Car X5H and its enablement.
This makes the U-Boot on RSIP usable beyond U-Boot shell running on
Cortex-M33, as the U-Boot on RSIP can now load not only SCP firmware
into the SCP core STCM, but also TFA BL31, OPTEE-OS and U-Boot into DRAM
and start them on the Cortex-A720AE core. This is self-contained and
affects only the R-Car X5H and a bit of R-Car V4H, besides it went
through rounds of testing until now, therefore it is safe to include it
this late in the release cycle. I know this will make rc5 massive, sorry
about that.
