The test doesn't pass, it might require more backport work before passing (likely culprit is 27041 but to be confirmed) |

1. Make the ROM_EXT detect the `secver_write` extension in the manifest. If present and the manifest security version is greater than the current boot_data minimum security version, update the value and write boot_data. 2. Add a string flag to the build system that allows the `secver_write` value to be set at build time. 3. Add a test which sequences firmware through a series of ROM_EXTs which advance the security version. Confirm each update and confirm that an older ROM_EXT will no longer execute. Signed-off-by: Chris Frantz <[email protected]> (cherry picked from commit 86dce8a)
