Hello Stefan,

these are another improvements for kwboot, please apply only after series
arm: mvebu: nandpagesize support for kwbimage v1

The main improvement is in patch 5, which changes where we inject the code
for changing baudrate back to 115200 Baud after fast upload. Instead of
injecting it before the main data image, we now inject it after.

This is because there are some kwb images that upload at address 0, and
injecting the code before that doesn't work, since there is no RAM mapped
at 0xfffff000.
