Hello! Here is a big changeset for RK3188 arch and Radxa Rock board. It brings support for updated DTS and booting from SD card as first-stage loader. DRAM setting blob from RK is required to boot (but this is unrelated to barebox). It lacks some unknown (for me) and requred initializations, so: 3.0 kernel from radxa repo boots fine. Mainline kernel gets a race in about 50%, and in another 50% works. It is disgusting, since I'd just wanted to try a newer kernel with this board. For not to spamming a ML with a long patches, it can be pulled from git tree: https://github.com/apxii/barebox/tree/rk/2up (based on next branch) Little howto: 1. Prepare SD card with bootfs and rootfs as usually. 2. Compile barebox make ARCH=arm radxa_rock_defconfig make ARCH=arm 3. Checkout and compile https://github.com/apxii/rkboottools 4. Get some RK3188 bootloader from https://github.com/neo-technologies/rockchip-bootloader 5. Run "rk-splitboot RK3188Loader(L)_V2.13.bin" command. (for example) You will get "FlashData" file with others. Otherwise it can be borrowed from RK U-boot sources from https://github.com/linux-rockchip/u-boot-rockchip/blob/u-boot-rk3188/tools/rk_tools/3188_LPDDR2_300MHz_DDR3_300MHz_20130830.bin 6. Run "rk-makebootable FlashData barebox-radxa-rock.bin rrboot.bin" 7. Insert SD card and run "dd if=rrboot.bin of=</dev/sdcard> bs=$((0x200)) seek=$((0x40))" 8.
