fsp_baytrail: Add the FSP version of Intel's Bay Trail-I chip
While similar to the Bay Trail-M/D code based on the MRC, there are many differences as well: - Obviously, uses the FSP instead of the MRC binaries. - FSP does additional hardware setup, so coreboot doesn't need to. - Different microcode & microcode loading method - Uses the cache_as_ram.inc from the FSP Driver - Various other changes in support of the FSP Additional changes that don't have to to with the FSP vs MRC: - Updated IRQ Routing - Different FADT implementation. This was validated with FSP: BAYTRAIL_FSP_GOLD_002_10-JANUARY-2014.fd SHA256: d29eefbb33454bd5314bfaa38fb055d592a757de7b348ed7096cd8c2d65908a5 MD5: 9360cd915f0d3e4116bbc782233d7b91 Change-Id: Iadadf8cd6cf444ba840e0f76d3aed7825cd7aee4 Signed-off-by: Martin Roth <gaumless@gmail.com> Signed-off-by: Martin Roth <martin.roth@se-eng.com> Reviewed-on: http://review.coreboot.org/5791 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
