This stuff is pretty ugly - would it not be better to make boards not
define this in the CONFIG_SPL_BUILD case in the first place, rather than
overriding them? As an example, I2C might be useful in SPL, but here it
would be hard (or even uglier) to add.

Just a question: can/should SPL be loaded to the internal SRAM instead of
DRAM?
