2008-11-28Flashrom already has the following probe functions:Carl-Daniel Hailfinger
- probe_spi_rdid with opcode 0x9f, usually 3 bytes ID - probe_spi_res with opcode 0xab, usually 1 byte ID We are missing the following probe function: - probe_spi_rems with opcode 0x90, usually 2 bytes ID RDID provides best specifity (manufacturer, device class and device) and RES is supported by quite a few old chips. However, RES only returns one byte and there are multiple flash chips with different sizes on the market and all of them have the same RES ID. REMS is from the same age as RES, but it provides a manufacturer and a device ID. It is therefore on par with the probing for parallel flash chips and specific enough. The order in which chips should be detected is as follows: 1. RDID 2. REMS 3.

2008-11-27The existing check in probe_spi_res() was right for SPI controllersCarl-Daniel Hailfinger
which support all commands, but may not exist. For controllers which support only a subset of commands, it will fail in unexpected ways. Even if a command is supported by the controller, it may be unavailable if the controller is locked down. The new logic checks if RDID could be issued and its return values made sense (not 0xff 0xff 0xff). In that case, RES probing is not performed. Otherwise, we try RES. There is one drawback: If RDID returned unexpected values, we don't issue a RES probe. However, in that case we should try to match RDID anyway.

2008-11-22msrtool: Release Candidate 1Peter Stuge
msrtool can decode MSRs and print the value of every field in human readable form. It can also be used to save a set of MSRs to a file, and at a later time compare the saved values with current values in hardware.

2008-11-18Currently flashrom assumes every vendor BIOS shares our view about whichCarl-Daniel Hailfinger
SPI opcodes should be placed in which location. Move to a less optimistic implementation and actually use the generic SPI read functions. They're useful for abstracting exactly this stuff and that makes them the preferred choice.

2008-11-18Check for failed SPI command execution in flashrom. Although SPI itselfCarl-Daniel Hailfinger
does not have a mechanism to signal command failure, the SPI host may be unable to send a given command over the wire due to security or hardware limitations. The current code ignores these mechanisms completely and simply assumes almost every command succeeds. Complain if SPI command execution fails. Since locked down Intel chipsets (like the one we had problems with earlier) only allow a small subset of commands, find the common subset of commands between the chipset and the ROM in the chip erase case. That is accomplished by the new spi_chip_erase_60_c7() which can be used for chips supporting both 0x60 and 0xc7 chip erase commands. Both parts of the patch address problems seen in the real world. The increased verbosity for the error case will help us diagnose and address problems better.
