Smaug: Add NVDEC and TSEC carveouts
The NV security team requested that coreboot allocate the NVDEC
and TSEC carveouts. Added code to set up NVDEC (1 region, 1MB)
and TSEC (2 regions, splitting 2MB), and set their lock bits.
Kernel/trusted code should be able to use the regions now.
Note that this change sets the UNLOCKED bit in Carveout1Cfg0
and Carveout4Cfg0/5Cfg0 (bit 1) to 0 in the BCT .inc files
(both 3GB and 4GB BCTs) so that the BOMs can be written.
Any future revisions to these BCT files should take this
into account.
BUG=None
BRANCH=None
TEST=Built and booted on my P5 A44. Saw the carveout regions
in the boot spew, and CBMEM living just below the last region
(TSEC). Dumped the MC GeneralizedCarveoutX registers and
verified their values (same as BCT, with only BOM/CFG0 changed).
