Autoload is the flash mirror mechanism that copies the content from the external SPI flash to the eflash. Actually, I never figured out what it is really useful for, since setting it to `on` causes the freshly flashed eFlash to be overwritten on the next EC reset.

Mirroring depends on the mirror enable bit and mirror size in both the internal's and the external`s flash. Thus, the code sets these in the image to be flashed to the eFlash.

IIRC verification does not cover the header (where these settings are located)
