Hi,

Imho you must copy the data from CAR, because when it is OFF, no writeback is
done to memory: (from BKDG)

Temporary data stored in the cache during boot cannot be written back to DRAM
after enabling the
DRAM controller using a CLFLUSH or WBINVB instruction. The cache should be
invalidated after the DRAM controller is initialized with an INVD instruction.

The later is imho not done in LB I think. Maybe needs fix?

Btw please design it to be suspend-to-ram friendly ;)
