Draft: rockchip: Ramboot and SPL DFU support
This PR is containing work from FUKAUMI Naoki naoki@radxa.com and Jonas Karlman jonas@kwiboo.se to get SPL DFU and ramboot support to u-boot for Rockchip devices. It is also containing some backports to make it apply / build / work.
The Ramboot patches have been sent to u-boot mailing list. The patches here are based on top of the v2 version from https://source.denx.de/u-boot/contributors/kwiboo/u-boot/-/commits/ramboot-v2. The version 2 has a fixup for RK3588, due to RAMboot issues with memory information provided as ATAGS by rockchip TPL.
The SPL DFU patches (which have some common dependencies with the ram boot ones) are from https://patchwork.ozlabs.org/project/uboot/list/?series=443761I've tested them on rk3399 (roc-rk3399-pc) and rk3588 (rock5c).
Note: To test on rock5c, I had to use some local patches compared to u-boot upstream.
