Hi Avik,

Even after using ioremapped addresses in omap_writel() I'm getting the oops.
Can you please point me to the location in mainline, where these l3 clocks
are enabled?
I guess you can find here:
l3_main_3_ick&& l3_instr_ick: arch/arm/mach-omap2/clock44xx_data.c
the clocks are set as ENABLE_ON_INIT.
Those clocks are also set ENABLE_ON_INIT in the linaro kernel. But still
it's hanging at "val = __raw_readl(base + LOCKSTATUS);" in cti_unlock(),
even after explicitly enabling it using:
omap_writel(1, CM_L3INSTR_L3_3_CLKCTRL);
omap_writel(1, CM_L3INSTR_L3_INSTR_CLKCTRL);
omap_writel(2, CM_EMU_CLKSTCTRL);
while ((omap_readl(CM_EMU_CLKSTCTRL) & 0x300) != 0x300);
BTW, the oops were fixed by replacing omap_writel with __raw_writel.

Avik
thanks,
