[util] Add support for EFI ROM images

2019-01-21T11:58:02+00:00

The Option::ROM module recognizes and checks EFI header of image. The disrom.pl utility dumps this header if is present. Signed-off-by: Michael Brown

[util] Improve processing of ROM images in Option::ROM

2019-01-21T11:56:35+00:00

The Option::ROM module now compares the Code Type in the PCIR header to 0x00 (PC-AT) in order to check the presence of other header types (PnP, UNDI, iPXE, etc). The validity of these headers are checked not only by offset, but by range and signature checks also. The image checksum and initial size also depends on Code Type. Signed-off-by: Michael Brown

[pci] Correct invalid base-class/sub-class/prog-if order in PCIR

2019-01-15T13:08:44+00:00

PCI Configuration Space contains fields prog-if at the offset 0x09, sub-class at the offset 0x0a and base-class at the offset 0x0b (it respects little endian). PCIR structure uses these fields in the same order. Signed-off-by: Michael Brown

[util] Use PCI length field to obtain length of individual images

2014-08-26T14:17:56+00:00

Option::ROM currently uses the initialisation length field (single byte at offset 0x02) to determine the length of a ROM image within a multi-image ROM file. For PCI ROM images with a code type other than 0, the initialisation length field may not be present. Fix by using the PCI header's image length field instead. Note that this does not prevent us from correctly handling ISA ROMs, since ISA ROMs do not support multiple images within a single ROM BAR anyway.

[util] Display UNDI ROM header in disrom.pl

[util] Allow for CALL NEAR in the option ROM initialisation entry point

2012-08-15T11:51:47+00:00

Option::ROM currently understands only JMP NEAR and JMP SHORT instructions in the initialisation entry point. At least one Broadcom option ROM has been observed to use a CALL NEAR instruction. Signed-off-by: Michael Brown

[romprefix] Report a pessimistic runtime size estimate

2012-07-23T16:57:40+00:00

PCI3.0 allows us to report a "runtime size" which can be smaller than the actual ROM size. On systems that support PMM our runtime size will be small (~2.5kB), which helps to conserve the limited option ROM space. However, there is no guarantee that the PMM allocation will succeed, and so we need to report the worst-case runtime size in the PCI header. Move the "shrunk ROM size" field from the PCI header to a new "iPXE ROM header", allowing it to be accessed by ROM-manipulation utilities such as disrom.pl. Reported-by: Anton D.
