The original assembly code of deep sleep bypass will cause build error
if both CONFIG_LOW_POWER_IDLE and CONFIG_LTO are defined when buildiing
board glkrvp/zoombini. This CL fixed it by change the bypass assembly code
from:
asm ("push {r0-r5}\n"
"ldr r0, =0x100A8000\n"
"wfi\n"
"ldm r0, {r0-r5}\n"
"pop {r0-r5}\n"
"isb\n"
);
to:
asm ("push {r0-r5}\n"
"wfi\n"
"ldm %0, {r0-r5}\n"
"pop {r0-r5}\n"
"isb\n" :: "r" (0x100A8000)
);
BRANCH=none
BUG=none
TEST=No build errors for "make buildall".
TEST=build zoombini/glkrvp with CONFIG_LOW_POWER_IDLE and CONFIG_LTO,
no build errors.
TEST=build npcx7_evb/npcx_evb and do stress test for deep idle->wakeup
on EVB, no symptom observed.
