How to select board config
Build environment
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）
