Change subject: [TEST]arch/x86/car.ld: Make the vboot tpm log symbols conditional ......................................................................
Patch Set 1:
Those vboot linker symbols conflicts with the ivybridge mrc.bin heap which is fixed at 0xff7e1000 with CONFIG_DCACHE_RAM_BASE at 0xff7e000. To properly fix that a separate car.ld or a lot of #if's are needed. Another option is to mess with the CAR setup which probably means using more MTRR's . If someone is capable of doing it a rebuild with the heap at a proper location would be nice.
