Preserve hardened firmware verification result

This bootloader patch changes how the result of a security check on the currently-running firmware is stored. Previously, the code immediately converted the secure verification result into a plain true/false boolean. Now it keeps the speci…

Harden firmware update validation

This commit changes how Passport's bootloader checks firmware updates. Previously, if the currently-running firmware failed validation, the bootloader would skip verifying the new update's signature and could install it anyway. Now the new…
