- Remove leading tabs from ifeq variable assignments (Make parse error)
- Move post-build steps (cp, dd, touch) out of dasharo-ec_target into
a proper Make rule; _target is now only make arguments
- Set dasharo-ec_output to ec.rom (the actual artifact, not .built)
- Add -$(BOARD) suffix to dasharo-ec_base_dir and dasharo-ec_dir so
v540tu and v560tu maintain independent build trees and ec.rom files
- Add explicit rule to copy and zero-pad ec.rom to 128 KB
- Fix coreboot copy rule: use FORCE + cmp so the recipe always runs
but only updates the destination (and its mtime) when content differs,
preventing the mtime race between boards sharing coreboot_base_dir
