[U-Boot] mt7623 bootup example

[Frank Wunderlich]

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-headers
 
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)

maybe you can add Infos above from my wiki. Btw. how far is the ethernet-driver? then i can replace my 2014-uboot ;)
 
regards Frank
