Having this in u-boot-ti/next results in

- All non-SDP3430 boards have

mem.c: In function 'gpmc_init':
mem.c:250: warning: assignment discards qualifiers from pointer target 
type

- Zoom2 fails to build with

zoom2.c:54: error: conflicting types for 'enable_gpmc_cs_config'
/include/asm/arch/sys_proto.h:38: error: previous declaration of 
'enable_gpmc_cs_config' was here

Reverting this patch makes both go away.

Then we get

sdp.c: In function 'board_init':
sdp.c:109: warning: passing argument 1 of 'enable_gpmc_cs_config' 
discards qualifiers from pointer target type
sdp.c:111: warning: passing argument 1 of 'enable_gpmc_cs_config' 
discards qualifiers from pointer target type
sdp.c:113: warning: passing argument 1 of 'enable_gpmc_cs_config' 
discards qualifiers from pointer target type
sdp.c:115: warning: passing argument 1 of 'enable_gpmc_cs_config' 
discards qualifiers from pointer target type

for SDP3430 only, though.

So I'd like to have this patch reverted in u-boot-ti/next and then

a) Fix sdp.c only

or

b) test the other boards, too, before applying this patch.

Best regards

Dirk
