Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot. This patch is adding minimal support to get U-Boot boot. U-Boot on R5 runs out of DDR with default configuration that's why DDR needs to be partitioned if there is something else running on arm64. Console is done via Cadence uart driver and the first Cadence Triple Timer Counter is used for time. This configuration with uart1 was tested on zcu100-revC. U-Boot 2018.05-rc2-00021-gd058a08d907d (Apr 18 2018 - 14:11:27 +0200) Model: Xilinx ZynqMP R5 DRAM: 512 MiB WARNING: Caches not enabled MMC: In: serial@ff010000 Out: serial@ff010000 Err: serial@ff010000 Net: Net Initialization Skipped No ethernet found.
