* Add support to get layout from fmap (e.g. coreboot rom)Arthur Heymans2018-10-231-2/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flashmap, or simply fmap, is a binary data format for describing region offsets, sizes, and certain attributes and is widely used by coreboot. This patch adds support for the fmap data format version 1.1 and adds --fmap and --fmap-file arguments. Using --fmap will make flashrom to search the ROM content for fmap data. Using --fmap-file will make flashrom search a supplied file for fmap data. An example of how to update the COREBOOT region of a ROM: flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT The fmap functions are mostly copied from cbfstool. Currently it is made mutually exclusive with other layout options until we are more clever about this input.

* Add support for reading the current flash contents from a filePaul Kocialkowski2018-02-111-3/+17
| | | | | | | | | | | | | | | | | | | When developing software that has to be flashed to a flash chip to be executed, it often takes a long time to read the current flash contents (for flashrom to know what pages to erase and reprogram) each time when writing the new image. However, when the flash was just reprogrammed, its current state is known to be the previous image that was flashed (assuming it was verified). Thus, it makes sense to provide that image as a file for the flash contents instead of wasting valuable time read the whole flash each time.

* Add support for Spansion S25FL127SJernej Škrabec2014-12-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | This flash chip can be configured (one time) to use 64 KiB or 256 KiB sectors. Additionally, in the 64 KiB mode it supports 16 4 KiB sub-sectors that can be (one time) programmed to be on the top or bottom of the device. The sub-sectors can be erased with the 0x20 opcode but because this opcode does not work with the remaining sectors and flashrom can not cope with that the 0x20 opcode is not supported yet. This patch adds two definitions, one for the 64 KiB and 256 KiB configuration respectively. The device also shares the RDID with the various S25FL128 devices so we have to increase the maximum number of successfully probed chips to 8. The 64 KiB mode was tested on real hardware.

| | | | | | | | | | | | | | | | | | - Create distinct functions for mapping and unmapping for flash chips. - Map only when needed: map before probing and unmap immediately after it. Map again when a single chip was probed successfully before taking any actual actions and clean up afterwards. - Map special function chip registers centrally together with flash space instead of within (some) probing methods after successful probes. - Save the used base addresses of the mappings in struct flashctx as well. - Do not try to (un)map the zero-sized chip definitions that are merely hacks. This also fixes the printing of wrong warnings for these chip definitions introduced in r1765. Corresponding to flashrom svn r1847.
