It won't, AFAICT. I removed TCM from the mappings in v2. Unfortunately,
the Telechips manual doesn't say much about it, but always calls it
"DTCM" or "Data TCM". I'll try to get more information, and come up
with a patch later. It's not really important ATM.

If I change things in arch/arm/kernel/tcm.c, I'll Cc: you anyway since
you're mentioned in the header. The code itself seems quite clear.

Thanks,
