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 usually is just important in kernel,  but 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)
