Henrik, can you provide us with some memorymap info of the first
32K of SRAM for when booted from FEL vs MMC for all of sun4i, sun5i
and sun7i ?

It would be good to know which bits of SRAM actually get uses by the BROM,
and thus should not be overwritten, and which ones are free to use.

Regards,

Hans
