r3774 build service

[coreboot information]

Dear coreboot readers!

This is the automated build check service of coreboot.

The developer "hailfinger" checked in revision 3774 to
the coreboot source repository and caused the following 
changes:

Change Log:
The existing check in probe_spi_res() was right for SPI controllers
which support all commands, but may not exist.
For controllers which support only a subset of commands, it will fail in
unexpected ways. Even if a command is supported by the controller, it
may be unavailable if the controller is locked down.

The new logic checks if RDID could be issued and its return values made
sense (not 0xff 0xff 0xff). In that case, RES probing is not performed.
Otherwise, we try RES.
There is one drawback: If RDID returned unexpected values, we don't
issue a RES probe. However, in that case we should try to match RDID
anyway.

Build Log:
Compilation of tyan:s2891 has been fixed

If something broke during this checkin please be a pain 
in hailfinger's neck until the issue is fixed.

If this issue is not fixed within 24h the revision should 
be backed out.

Best regards,
