Pull request overview
Updates rpi-eeprom-update to make the “minimum bootloader version required by hardware” (from DT/OTP) check configurable, and documents the new knob in the default config template.
Changes:
- Add
STRICT_MIN_VER_CHECK(defaulting via env/config) to control whether a min-version mismatch is fatal. - Move the MFG_VER vs board minimum version check into the common update path (
applyRecoveryUpdate), emitting a warning and optionally exiting. - Document
STRICT_MIN_VER_CHECKinrpi-eeprom-update-default.
