Subject: board: xilinx: zynqmp: Register alternate FPGA device for zu63dr_SE
X-Git-Tag: v2026.07-rc1~20^2~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=106a7f7d7fd2ff5529e6899d1856430f5140bc08;p=thirdparty%2Fu-boot.git

board: xilinx: zynqmp: Register alternate FPGA device for zu63dr_SE

The zu63dr_SE and zu67dr_SE devices share the same silicon ID code
0x046D7093 and cannot be distinguished at runtime. The SOC driver
reports zu67dr_SE for this ID, which causes fpga loadb to reject
zu63dr_SE bitstreams.

Register zu63dr_SE as an alternate FPGA device when zu67dr_SE is
detected. This allows users to load either bitstream by selecting
the appropriate device number:
  - Device 0 (zu67dr_SE): fpga loadb 0 ${loadaddr} ${filesize}
  - Device 1 (zu63dr_SE): fpga loadb 1 ${loadaddr} ${filesize}
