Subject: Update SCCR programming in cpu_init_f() to support all 83xx processors
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=df33f6b4d6d63693dd9200808b242de1b86cb8e8;p=u-boot.git

Update SCCR programming in cpu_init_f() to support all 83xx processors

Update the cpu_init_f() function in cpu/mpc83xx/cpu_init.c to program the
bitfields for all 83xx processors.  The code to update some bitfields was
compiled only on some processors.  Now, the bitfields are programmed as long
as the corresponding CFG_SCCR option is defined in the board header file.
This means that the board header file should not define any CFG_SCCR macros
for bitfields that don't exist on that processor, otherwise the SCCR will be
programmed incorrectly.
