This allows u-boot to load different OS or Bare Metal application on
different cores of the i.MX6 SoC.
For example: running Android on cpu0 and a RT OS like QNX/FreeRTOS on cpu1.

I didn't notice this patch until it got merged. Why dropping CONFIG_MP here?
This change breaks these boards

Sorry, I didn't see the break for these boards.
'asm/mp.h' is used only for the powerpc board and using CONFIG_MP force
the other architecture (or board) to create an empty header.
As this header was here to use only specific features (not generic), I
removed it and put the include guards only for the boards needed.
Can't we add these boards to the board_f.c?
Regards,
Gabriel
