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.

2008-11-18Check 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.

2008-07-07flashrom: Trivial SPI cleanupsPeter Stuge
While writing a new SPI driver I fixed some things in the SPI code: All calls to spi_command() had unneccessary #define duplications, and in some cases the read count define could theoretically become harmful because NULL was passed for the read buffer. Avoid a crash, should someone change the #defines. I also noticed that the only caller of spi_page_program() was the it87 driver, and spi_page_program() could only call back into the it87 driver. Removed the function for easier-to-follow code and made it8716f_spi_page_program() static. The ichspi driver's static page functions are already static.

2008-06-22flashrom: Remove dead M-Systems Disk on Chip codePeter Stuge
DOC support has been disabled by default for many years. The write function does nothing but print text. It has a call to write_page_md2802() commented out, but that function does not exist. This is dead code with ugly #ifdefs. Updates README to reflect that there was a time when there was code, but it didn't work. Removes M-Systems #defines and also includes svn rm msys_doc.* Signed-off-by: Peter Stuge <peter@stuge.se> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3382 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2008-06-18flashrom: Add support for AMIC Technology A49LF040A and do not probe ↵Jens Kuehnel
W29EE011 anymore Jens sent the first patch that added A49LF040A to flash.h and flashchips.c using _jedec and _49lf040 functions. An issue was found with probe_w29ee011() for the Winbond W29EE011, which caused the A49LF040A to no longer respond to any commands. Ward made a patch to disable probing by default for the W29EE011 following some discussion. Using -c W29EE011 will make flashrom probe for the chip. Peter did some more datasheet diving and found that the Pm49FL00x functions suited this chip quite well because of the block locking registers in A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3. Ward confirmed that this works on alix.2c3 too.

2008-06-18flashrom: Force read unknown flash chipsPeter Stuge
When flash chip detection fails, it is still useful and possible to read the flash chip contents. If no flash chip is found in normal probes and the -f -r -c CHIPNAME options are given, a successful probe for the specified chip is forced, and then flashrom reads the flash chip using either the read function for the specified chip, or if there is none, a simple memcpy(). The patch also moves the global variable int force in flashrom.c into main() and passes it as a parameter to layout.c:show_id(), which was the only other function that used the variable. This is needed to avoid confusion with the new parameter int force which is added to flashrom.c:probe_flash() and used to force probe success for the chip named in char *chip_to_probe.

2008-05-17flashrom: Support Pm49FL004/2 Block Locking RegistersNikolay Petukhov
The PMC chips understand both LPC and FWH flash commands. When in FWH mode (MSR_DIVIL_BALL_OPT(0x51400015) = 0x00000f7d on 5536 boards) the Block Locking Registers by default lock the flash chip for write and erase - in addition to any chipset write protection. This patch adds unlock operations before Pm49FL004/2 write and erase, and it includes an svn mv pm49fl004.c pm49fl00x.c Thanks go to Nikolay for this patch.
