powerpc: tqm834x: Fix build warnings in initdram()
With gcc 4.9, it produces the following warnings:
CC board/tqc/tqm834x/tqm834x.o
board/tqc/tqm834x/tqm834x.c: In function 'initdram':
board/tqc/tqm834x/tqm834x.c:325:12: warning: iteration 3u invokes undefined behavior [-Waggressive-loop-optimizations]
(((base + size - 1) >> CSBNDS_EA_SHIFT) &
^
board/tqc/tqm834x/tqm834x.c:80:2: note: containing loop
for(cs = 0; cs < 4; ++cs) {
^
There is an integer overflow when cs = 3. To fix it, change
parameters of set_cs_bounds() to ulong.
