Hi all,
It looks like we can cache now the whole ROM while in CAR (i showed that in the analysis posted earlier, it works too ;)
The attached patch does that. Comments?
Marc and I thinks we can add some safeguard to check if any L2 data was evicted during CAR to RAM. This is just few instructions to enable the PerfCounter and then read it in the post_cache_as_ram. I will post this as separate patch.

I did not test this particular patch however it does work with similar changes already. I take this patch as think for RFC, if it is enough to change it like this.
Does this fix the slowness of copying coreboot_ram to ram?
I don't expect this to fix the slow lzma decomress. The disable_car code still changes the MTRR settings. That needs to be sorted as well.
