[PATCH] board: rockchip: add ArmSoM Sige5 RK3576 board

Fri Jun 27 04:53:48 CEST 2025

ArmSoM Sige5 is a Rockchip RK3576 based SBC (Single Board Computer) by
ArmSoM.

This is the second board of ArmSoM supported by u-boot, so I change the
dir in MAINTAINERS to board/armsom/.

Booting from emmc is tested.
