* vboot2: Scramble the GBB magic numberDaisuke Nojiri2014-06-252-1/+14
| | | | | | | | | | | | | | | | Compiling in the GBB magic number as is causes any tools that search for the number to fail. This patch allows firmware to embed XOR'ed signature. TEST=Booted Nyan in normal mode. FAFT:firmware_DevMode passes.

* vboot2: More specific errors for unimplemented external APIsRandall Spangler2014-06-241-0/+6
| | | | | | | | | | | | | | | When porting vboot2 to a platform, it's common to copy 2stub.c and then start implementing APIs. Adding explicit errors makes it clearer when an unimplemented API is called.

More specific error codes coming to other files next, but I don't want this CL to get too long. This also changes test_common.c so TEST_EQ() reports mismatched values in both decimal and hex, and adds TEST_SUCC() to test for a successful return value.
