Yes, very similar. If you look at the board configs you'll see that
almost everything is common. The only difference is the features that
are enabled in SPL (for code size reasons at present it doesn't
support both SPI and MMC booting).

When you change out the device tree it should boot on any of the
RK3288 platforms. There is nothing hardware-specific in the
implementation or config. Everything uses driver model and device
tree.

Simon
