[PATCH v2 5/5] board: rockchip: Add Radxa ZERO 3W/3E

Sat Aug 3 00:12:23 CEST 2024
The Radxa ZERO 3W/3E is an ultra-small, high-performance single board
computer based on the Rockchip RK3566, with a compact form factor and
rich interfaces.
Implement rk_board_late_init() to set correct fdtfile env var and
board_fit_config_name_match() to load correct FIT config based on what
board is detected at runtime so a single board target can be used for
both board models.
Features tested on a ZERO 3W 8GB v1.11:
- SD-card boot
- eMMC boot
- USB gadget
- USB host
Features tested on a ZERO 3E 4GB v1.2:
- SD-card boot
- Ethernet
- USB gadget
- USB host
