Just to be clear...i tested v2 patches on rc1 (https://github.com/frank-w/u-boot/tree/bpi-r2_v2) they working well.
v3 have additional depencies (swig,python-dev same on rc1&rc3) and bootargs seems not to be passed to kernel (rc1=bpi-r2_v3_old and rc3 = bpi-r2_v3)
That's because I remove 'gd->bd->bi_boot_params' in v3, but it seems you use legacy method (ATAGs) to pass parameters. I will add it back.

Hi Simon, hi Ryder,
i tried Patches so far, they are working well
https://patchwork.ozlabs.org/patch/992398/
here my github-repo with steps to build:
https://github.com/frank-w/u-boot
there is a build.sh, which compiles uboot the common way with some additions like bootmenu and full environment to load a kernel on BPI-R2
here are instructions how to prepare SD-Card for boot-up:
https://www.fw-web.de/dokuwiki/doku.php?id=en:bpi-r2:storage#extended_boot-h...
as you see you need 3 Headers on SD-Card (SDMMC_BOOT, BRLYT, Preloader) and the uboot.bin for SD-Card. on emmc imho preloader in boot0-block and uboot on main-Partition is enough for uboot to boot

btw. @ryder.lee you have a small typo in the readme: Boorom => Bootrom (2 times)
Thanks for catching that.
maybe you can add Infos above from my wiki. Btw. how far is the ethernet-driver? then i can replace my 2014-uboot ;)
OK.
Thanks Ryder
