Change the prototype of kirkwood_mpp_conf() from void kirkwood_mpp_conf(u32 *mpp_list) to void kirkwood_mpp_conf(const u32 *mpp_list) Now we can declare the kwmpp_config static and const where possible.

Declaring the mpp_config static avoids generating the array on the stack. This was compile tested on all kirkwood boards and tested on the lschlv2. arch/arm/cpu/arm926ejs/kirkwood/mpp.c | 2 +- arch/arm/include/asm/arch-kirkwood/mpp.h | 2 +- board/LaCie/net2big_v2/net2big_v2.c | 2 +- board/LaCie/netspace_v2/netspace_v2.c | 2 +- board/Marvell/dreamplug/dreamplug.c | 2 +- board/Marvell/guruplug/guruplug.c | 2 +- board/Marvell/mv88f6281gtw_ge/mv88f6281gtw_ge.c | 2 +- board/Marvell/openrd/openrd.c | 2 +- board/Marvell/rd6281a/rd6281a.c | 2 +- board/Marvell/sheevaplug/sheevaplug.c | 2 +- board/Seagate/dockstar/dockstar.c | 2 +- board/buffalo/lsxl/lsxl.c | 2 +- board/d-link/dns325/dns325.c | 2 +- board/keymile/km_arm/km_arm.c | 2 +- 14 files changed, 14 insertions(+), 14 deletions(-)
