Dear Ricardo Ribalda Delgado,

I guess you mean "do *not* need gap fill" ?

This is not correct. The U-Boot image does not occupy any low memory
- low memory is reserved for RAM, while the U-Boot image is stored in
ROM. ROM is typically mapped in high memory, often close to the end
of the physical address space.

Incorrect again. The U-Boot image never exceeds the physical size of
the ROM. Typically the U-Boot image size is well below 256 KiB, with
few systems (which include graphics support and other complex stuff)
going up to 512 KiB.

I think your patch makes sense and could be applied, but the commit
message is too incorrect. Please fix this and resubmit.
Best regards,
Wolfgang Denk
