ii used to rely on errno for exit status, but this was flawed.

when removing it, i neglected to adjust the actual error exits,
setting errno accordingly. this patch should fix it. this is
important for scripts that use nvmutil, which may rely on its
error status upon exit.

This reverts commit 154c5ff319a5fdc3f55520f483c014f8aeabee16.

this one is still needed, for x2e n150

This reverts commit fedeb6ecd8b5f3ed79dad754e452aecf88cbdde2.

this, along with several other updates, have been reverted.
dell 3050 micro had boot issues, on the update. i therefore
revert the recent revision update, pending further investigation.

thanks to sirlami on irc for pointing this out.

due to lbmk blob policy, we must not distribute
fsp except as the full, concatenated binary, thus
complying with intel's license. it is removed from
builds before release, re-inserted via vendor
inject scripts in the usual way.

a while ago, coreboot updated fsp but i had to keep
it on the earlier version for this board, lest old
releases no longer match vendor insertion; the new
fsp version also wasnet well tested, and didn't seem
to contain any changes reported that pertained to
our use of it.

the fsp headers do not match the fsp binary in use,
causing boot issues for users on topton x2e n150.
this patch should fix the issue, as reported by
sirlami who is the one who found and first tested
this fix; i'm simply changing the configuration,
as per sirlami's guidance.
