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. Boot from SD card
