fpga: zynqmp: support loading encrypted bitfiles

2022-07-26T07:34:21Z

Add supporting new compatible string "u-boot,zynqmp-fpga-enc" to handle loading encrypted bitfiles. This feature requires encrypted FSBL, as according to UG1085: "The CSU automatically locks out the AES key, stored in either BBRAM or eFUSEs, as a key source to the AES engine if the FSBL is not encrypted. This prevents using the BBRAM or eFUSE as the key source to the AES engine during run-time applications."

fpga: zynqmp: reduce zynqmppl_load() code

2022-07-26T07:34:21Z

Reduce the function code by calling xilinx_pm_request() once only. Use the same variable bsize_req to store either bstream size in bytes or an address of bstream size according to a type required by the firmware version. Remove obsolete debug().
