The most important part is setting up the stack, which is basically
configuration of CONFIG_SYS_INIT_RAM_* and CONFIG_SYS_INIT_SP_*
This part is needed for the code that is going to end up being called
from board_init_f function, which includes dram_init and early serial
console init.

You will also need

#define CONFIG_SYS_INIT_SP_OFFSET  (GENERATED_GBL_DATA_SIZE)

or just leave CONFIG_SYS_INIT_SP_ADDR defined as it is, but I guess
that's less idiomatic.

This is just a difference between plain text mode & "Rich Text" mode.
This one should be wrapped normally (that is, if you trust the
documentation).
