originally work by Jate Sujjavanich <jsujjavanich@syntech-fuelmaster.com> ---- The defines in arch/m68k/include/coldfire/flexbus.h are not compatible with the 5235 processor. The registers in struct fbcs are different sizes from those in the 5235. Also, the defines are a little different. This is what I have so far. Comments? ---- Reformat the patch manually by Jason Jin Signed-off-by: Jate Sujjavanich <jsujjavanich@syntech-fuelmaster.com> Signed-off-by: Jason Jin <Jason.jin@freescale.com>
