Subject: [build] Avoid generating ROMs with "match-any" vendor or device IDs
X-Git-Tag: v1.20.1~2168
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b99d2af0cdcedcaaf9a69a0c758b8a7e644236a;p=thirdparty%2Fipxe.git

[build] Avoid generating ROMs with "match-any" vendor or device IDs

A PCI_ROM() entry containing a vendor or device ID of PCI_ANY_ID
(0xffff) indicates to pci_find_driver() that the entry's vendor or
device ID should be ignored when matching against the device's vendor
or device ID.  It does not represent a PCI ROM that should be built.
