The CONFIG_FLASH_NVMEM option implements persistent, reliable storage
regions in flash. This adds CONFIG_FLASH_NVMEM_VARS, which uses one of
those storage regions for free-form variables.
Refer to the comments in include/nvmem_vars.h and common/nvmem_vars.c
for usage and implementation details.
BUG=chrome-os-partner:61107
BRANCH=none
TEST=make runtests
This CL includes a number of new tests, specifically for this feature.
No target boards use this feature yet so there's nothing to test on
actual hardware, but the test/nvmem_vars executable includes console
commands ("get", "set", "print") to try it out.
