* ARM: zynqmp: zcu104: register update handlerMichael Tretter2021-06-252-0/+19
| | | | | | | | | | | As the zcu104 stores the environment in the same partition as the barebox image, the partition is already mounted in ENV_MNT_DIR ("/boot"). Therefore, the update handler has to use the already existing mount point for the update.

* ARM: zynqmp: add support for Xilinx ZCU104 boardMichael Tretter2018-12-103-0/+35
Add support for the Xilinx Zynq Ultrascale+ MPSoC architecture (ZynqMP) and the Xilinx ZCU104 board. Barebox is booted as BL33 in EL-1 and expects that a BL2 (i.e. the FSBL) already took care of initializing the RAM. Also for debug_ll, the UART is expected to be already setup correctly. Thus, you have to add the Barebox binary to a boot image as described in "Chapter 11: Boot and Configuration" of "Zynq Ultrascale+ Device Technical Reference Manual".
