[U-Boot-Users] [PATCH] Fix AMCC bootstrap option letter label order

[Jeff Mann]

U-boot Users:

Several of the AMCC 440 processors have a stupid 'error' in the user
manual resulting in the logical order of option 'G' and option 'F' being
labeled in reverse. (The logical order of the bootstrap pins represent
settings from 0 through 7, while the letters are ordered A, B, C, D, E,
G, F, H.) In my case, I found this problem affecting the 440EPx and GRx
processors. 

See table 8-2 in the 440EPx Users' Manual.

The option AMCC_PINSTP_F_G_REVERSED has been added to these processors
where they appear in cpu.c where the array bootstrap_str[] is located.
Code to reverse a bootstrap setting of 5 and 6 (corresponding to G and
F) has been added to bootstrap_option(). I know that this problem
affects more processors in this family, so other users should add this
option when they are identified. 

Patch attached.
