As of this commit the following variables are supported:
* @BOARD_BUILD_DIR@ - absolute path under build/

EC signatures requires that the digest has the corresponding length. Removing the hardcoded sha2-256 hash function and adding support of sha2-384 and sha2-512 should allow using EC crypto.
Testing point:
- All board configs not explicitely stating export CONFIG_USB_KEYBOARD=y should not have any impact
- librem_l1um, kgpe-d16_workstation-usb_keyboard, librem_mini_v2 and librem_mini will loose USB Keyboard input with this commit alone.
This reduces the amount of noise in the Linux kernel config files
by only storing the differences from the stock configuration.
It adds a new makefile target 'linux.saveconfig' to convert the
build tree's .config file into config/linux-linuxboot.config.
