This fixes the following: => sf probe SF: Detected mx66lm1g45g with page size 256 Bytes, erase size 4 KiB, total 128 MiB => reset resetting ... RomBOOT
What happened is that in u-boot the mx66lm1g45g NOR flash enters in Octal DTR mode. The user reset calls do_reset() method which does not call any driver's remove method, but merely resets the CPU. The flash remains in Octal DTR mode and RomCode can't recognize it, thus the boot will fail. More details in the commit messages.
Tested after software reset the mx66lm1g45g NOR flash, but also GMAC0/1, all went fine.
