Currently, per-board defines use mixed case (BOARD_pit). This causes
the presubmit script to complain because that's a style violation.
Using --no-verify to bypass that also allows other style violations to
creep in.
This change adds uppercase variants (BOARD_PIT). It also adds a CORE_
define with '-' changed to '_', since CORE_cortex-m isn't a valid
symbol but CORE_CORTEX_M is (so now we can #ifdef CORE_CORTEX_M).
This does not remove the old mixed-case defines yet, nor does it
find/replace them in the C source files. This is intentional, so this
change can be cherry-picked into branches without needing to change
files in the branch that may have picked up new #ifdefs.
I will rename the constants in the C source files and remove the old
mixed-case defines in a follow-on CL, which should not need to get
picked into existing branches.

BRANCH=none (but might need it if you later cherry-pick something with
an uppercase #ifdef BOARD_FOO
TEST=Build each board with V=1 option: 'make V=1 BOARD=foo all tests'.
Check that the compile command line has both mixed-case and
uppercase defines. Check that per-board tests from test/build.mk
were built (for example, BOARD_PIT should compile kb_scan and
stress, and BOARD_SAMUS should build none of them).

In the most general case, the flash layout looks something like this: +---------------------+ | Reserved for EC use | +---------------------+ +---------------------+ | Vblock B | +---------------------+ | RW firmware B | +---------------------+ +---------------------+ | Vblock A | +---------------------+ | RW firmware A | +---------------------+ +---------------------+ | FMAP | +---------------------+ | Public root key | +---------------------+ | Read-only firmware | +---------------------+ BIOS firmware (and kernel) put the vblock info at the start of each image where it's easy to find. The Blizzard EC expects the firmware vector table to come first, so we have to put the vblock at the end. This means we have to know where to look for it, but that's built into the FMAP and the RO firmware anyway, so that's not an issue. The RO firmware doesn't need a vblock of course, but it does need some reserved space for vboot-related things. Using SHA256/RSA4096, the vblock is 2468 bytes (0x9a4), while the public root key is 1064 bytes (0x428) and the current FMAP is 644 bytes (0x284). If we reserve 4K at the top of each FW image, that should give us plenty of room for vboot-related stuff.
