Why master was not enforcing CONFIG_CBFS_SIZE=0xBE4FFF as all other 12mb opaque flash chips from ivy bridge? (was 8mb). Merged as emergency fix: untested. Unfortunately reason was that anything CBFS bigger then 8mb will make Haswell boot in 50s, thanks to improper MRC blob we depend on.

Solution would be to switch to NRI #1711, which is not merged upstream.
Board owners: time to participate testing/reviewing/commenting upstream your need/appreciation of memory initialization being free under #1711.

OLD
#1826 was merged moving those boars to untested to prevent users from potential bricking without external programmers.

Testing needed from boards testers (BOARDS_TESTERS.md):

• t440p: @fhvyhjriur @ThePlexus @srgrint @akunterkontrolle @rbreslow
• w541 (similar to t440p): @ResendeGHF @gaspar-ilom (Always tested late: Needs more responsive board testers or risk to become unmaintained.)

TESTED: Master roms will boot, but after 50s see #1825 (comment)

Therefore, t440p/w541 boards now build UNTESTED tagged board roms. Be warned.
