Detailed Description

FileName: arch/arm/mach-omap/omap3_clock.c

prcm_init This is the second level clock init for PRCM as defined in clocks.h -- called from SRAM, or Flash (using temp SRAM stack).

During reconfiguring the clocks while in SDRAM/Flash, we can have invalid clock configuration to which ARM instruction/data fetch ops can fail. This critical path is handled by relocating the relevant functions in omap3_clock_core.S to OMAP's ISRAM and executing it there.

Warning:

IMPORTANT: These functions run from ISRAM stack, so no bss sections should be used, functions cannot use global variables/switch constructs.
