"/usr/libexec/microcode_ctl/update_ucode" to add it to firmware directory

* "pci_config_val" performs check for specific values in selected parts
of configuration space of specified PCI devices. If "-m" option
is not specified, then the actual check is skipped, and the check returns
result in accordance with the provided "mode" option (se below). Check
arguments are a white-space-separated list of "key=value" pairs.
The following keys are supported:
* "domain" - PCI domain number, or "*" (an asterisk) for any domain.
Default is "*".
* "bus" - PCI bus number, or "*" (an asterisk) for any bus. Default is "*".
* "device" - PCI device number, or "*" (an asterisk) for any device.
Default is "*".
* "function" - PCI function number, or "*" (an asterisk) for any function.
Default is "*".
* "vid" - PCI vendor ID, or empty string for any vendor ID. Default

* "did" - PCI device ID, or empty string for any device ID. Default
is empty string.
* "offset" - offset in device's configuration space where the value resides.
Default is 0.
* "size" - field size. Possible values are 1, 2, 4, or 8. Default is 4.
* "mask" - mask applied to the values during the check. Default is 0.
* "val" - comma-separated list of matching values. Default is 0.
* "mode" - check mode, the way matches are interpreted:
* "success-any" - check succeeds if there was at least one match,

* "success-all" - check succeeds if there was at least one device checked

* "fail-any" - check fails if there was at least one match, otherwise
it succeeds.
* "fail-all" - check fails if there was at least one device checked

It interprets 4 bytes at offset 0x84 of special files "config" under
directories that match glob pattern "/sys/bus/pci/devices/*:*:1e.3"
as an unsigned integer value, applies mask 0x38 (thus selecting bit 5..3
of it) and checks whether it is one of the values 0x38, 0x18, or 0x8 (0b111,
0b011, or 0b001 in bits 5..3, respectively); if there are such files,
and all the checked values in every checked file has matched at least one
of the aforementioned value, then the check is successful, otherwise
it fails (in accordance with "mode=success-all" semantics). This check fails
