How to select board config

DDR:

We use opensource idbloader(See Boot_option)  on some chips (rk3036, rk3288) and its dmc driver can't support ddr-type autodetct, so the wrong ddr dts settings will make the board failed to enter u-boot.

PMIC:

PMIC setting in u-boot don't have much matter. Just for the board using rk818, USB input current should be configured during boot stage.

Boot:

Please note some board have disable emmc in u-boot though the hardware actually have emmc. (firefly-rk3288)

 

Board config

defconfig and dts

Every Board has its device tree file and config file required by the kernel and uboot. Therefore, you will need to choose the correct dts and config to build the source.Below list various Boards and the matching file.
