The hardware engineer is initializing the DDR memory correctly. Otherwise
we won't be able to read/write to the memory.
As I understand, the GOT table is used for relocating the exception vectors.
I am most likely crashing while copying the fixups or when doing a cache
flush.
In start.S, if I disable the ICACHE & do not run the cache POST test which
Enables the I-cache and never disables it, I should be fine. Unless its
some 852T processor cache bug. We had problem with ICTRL with value of 7.
Value of 3 seems to work better. Processor is at 50MHz and memory is at
100MHz with TA line based handshake ( so atomic).
