From: Xu Ziyuan <xzy.xu@rock-chips.com>

If we would like to boot from SD card, we have to implement mmc driver
in SPL stage, and get a slightly large spl binrary. RK3288's bootrom code
has the ability to load spl and u-boot, then boot.

If CONFIG_ROCKCHIP_RK3288_SPL_BACKTO_BROM is enabled, the spl will
return to bootrom in board_init_f(), then bootrom load u-boot binrary.

This patch does that.

Loading sequence after rework:
bootrom ==> spl ==> bootrom ==> u-boot

Changes in v3:
- Add CONFIG_ROCKCHIP_RK3288_SPL_BACKTO_BROM for enabling this feature
- Update doc/README.rockchip to instruct how to use it
- Detailed commit message

Changes in v2:
- Add sdcard iomux initlization in board_init() to fix sdmmc command
sending timeout issue when booting from eMMC

I'm going to apply this, but please can you send a follow-up patch (to
u-boot-rockchip/testing) to fix the nits below?

How about CONFIG_ROCKCHIP_SPL_BACK_TO_BROM?

I think this could be implemented for any SoC.

Also please add this to Kconfig as we should not be adding new CONFIG
options that are not in Kconfig.

If you make this a generic Rockchip option then it should be enabled
for RK3036 by default.

Can you flip that to an ifdef?

Also please add a comment as to why it needs to be 0.

This patch had already apply to u-boot/rockchip, I can't revise commit' 
nits.
I had revise the glitches according to your opinion. May I send patch 
V4, and you revert the former commit?
