[PATCH] bootm: change default verification mode from hash to available

[PATCH] bootm: change default verification mode from hash to available

[Ahmad Fatoum]

The default of global.bootm.verify=hash means that barebox will refuse
to boot images without hashes, but won't bother verifying the signature.

For verified boot setups, this parameter needs to be set to signature,
preferably enforced via CONFIG_BOOTM_FORCE_SIGNED_IMAGES.

For everything else, it's better user experience if barebox would just
verify what's available instead of refusing to boot images without hashes,
like the image.fit that Linux can now generate as part of its build.
