2009-04-25The flashrom makefile wants to redirect both stdout and stderr toStephan Guilloux
/dev/null for one compile test. The old variant of using &>/dev/null works on bash and zsh, but not on dash and tcsh. dash and tcsh interpret it as "background command and truncate /dev/null" which is not what we want. >& works on tcsh and bash, but it is not POSIX compliant. Since make uses /bin/sh and /bin/sh has to be POSIX compliant, we can use the POSIX variant of stderr and stdout redirection. >/dev/null 2>&1 is POSIX compliant. This is specified in SuSv3, Shell Command Language, sections 2.7.2 and 2.7.6.

2009-04-22All "unknown xy SPI chip" entries claim to have status UNTESTED forCarl-Daniel Hailfinger
probe/read/erase/write. That is incorrect. A bit of confusion comes from how the #defines are named. We call them TEST_BAD_*, but the message printed by flashrom says: "This flash part has status NOT WORKING for operations:" Something that is unimplemented is definitely not working. Neither of the chip entries mentioned above has erase or write functions implemented, so erase and write are not working. Since their size is unknown, we can't read them in. That means read is not working as well. Probing is a different matter. If a chip-specific probe function had matched, we wouldn't have to handle the chip with the "unknown xy SPI chip" fallback. I'm tempted to call that "not working" as well, but I'm open to discussion on this point.

2009-04-20flashrom: board_enables: reconstruct table.Luc Verhaegen
This patch restores the pciid based board matching table. It makes this table readable and hackable again, and the only disadvantage is that the right margin is way beyond the rather dogmatic 80. All 0x0000 pci ids have been string replaced by 0 to more easily spot missing ids, and extra comments have been added to explain how the various entries are used.

2009-03-17This patch adds "high coreboot table support" to coreboot version 2.Stefan Reinauer
Some bootloaders seem to overwrite memory starting at 0x600, thus destroying the coreboot table integrity, rendering the table useless. By moving the table to the high tables area (if it's activated), this problem is fixed. In order to move the table, a 40 bytes mini coreboot table with a single sub table is placed at 0x500/0x530 that points to the real coreboot table. This is comparable to the ACPI RSDT or the MP floating table. This patch also adds "table forward" support to flashrom and nvramtool.

2009-03-05flashrom: Use helper functions to access flash chips.Carl-Daniel Hailfinger
Right now we perform direct pointer manipulation without any abstraction to read from and write to memory mapped flash chips. That makes it impossible to drive any flasher which does not mmap the whole chip. Using helper functions readb() and writeb() allows a driver for external flash programmers like Paraflasher to replace readb and writeb with calls to its own chip access routines. This patch has the additional advantage of removing lots of unnecessary casts to volatile uint8_t * and now-superfluous parentheses which caused poor readability. I used the semantic patcher Coccinelle to create this patch. The semantic patch follows: @@ expression a; typedef uint8_t; volatile uint8_t *b; @@ - *(b) = (a); + writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + readb(b) @@ type T; T b; @@ ( readb | writeb ) (..., - (T) - (b) + b ) In contrast to a sed script, the semantic patch performs type checking before converting anything.

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.

2008-11-18Currently 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.
