Now that I am using white-space mode in Emacs I can see all of this,
and I don't like it :-)

Adds data offset to PCI expansion ROM Data Structure in resource
describing Expansion ROMs. This allows AHCI OROM scanning function
to identify AHCI OROM by device id 0x2822 and vendor id 0x8086.

This produced lots of warning, some of which pointed to actual bugs.

The PCI-3.0 Firmware specification allows for option-roms to have
512-byte alignment rather than 2048-byte. As there does not appear to
be a reliable method to detect a PCI-3.0 compliant BIOS from userspace
we allow the imsm platform detection code to presume that a system
modern enough to have an Intel AHCI controller does not have
dangerous/legacy ISA regions in the option-ROM memory space.
An environment variable to disable this behaviour, IMSM_SAFE_OROM_SCAN,
is added in case this presumption is ever proven wrong.

This provides at least a kernel bug compatible method of scanning for an
adapter-rom.
