Subject: [PATCH] ubootRock3C: init at 2026.04

Add U-Boot package for Radxa Rock 3C single-board computer (Rockchip RK3566).

Uses the rock-3c-rk3566_defconfig with armTrustedFirmwareRK3568 BL31 and
rkbin RK3566 TPL. Installs idbloader, u-boot.itb, and rockchip combined
images for both eMMC/SD and SPI flash boot.
