* Allow the registration of functions to be called at programmer shutdownCarl-Daniel Hailfinger2010-02-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some programmers want to run certain functions during programmer shutdown, but the function choice depends on the code path taken during programmer init. Rather than rebuilding the whole init logic in the shutdown function, it is now possible to register functions for execution on programmer shutdown. The behaviour is similar to atexit(), but the registered functions will be run on programmer shutdown instead of on exit and the functions will be called with a void * argument that is specified on registration. Registered functions must have the prototype void function(void *); and will be executed in reverse registration order directly before calling the programmer-specific shutdown() function. It is recommended to have shutdown() only disable programmer/hardware access and leave all code path sensitive shutdown to functions registered with register_shutdown(). The most prominent use case is resetting the EC after flashing on laptops. Note: There are quite a few code paths in flashrom which proceed to terminate flashrom without any programmer shutdown. Those code paths will not get the benefit of register_shutdown() and they should be changed wherever possible. Corresponding to flashrom svn r904.

* Create a physical memory mapping function which requests cached readonly memoryCarl-Daniel Hailfinger2010-02-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | This should take care of picky Linux kernels which do not allow uncached mappings to cached areas. Handle mapping failure gracefully (no forced exit()) if the caller specifies it. Such cached areas which can handle mapping failure are DMI tables and coreboot tables. On failure we just ignore those tables. That is not perfect, but a lot better than aborting flashrom due to an error in nonessential functionality. This should fix flashrom on a sizable number of machines where it currently aborts early. Yes, I could have exploited a Linux kernel bug to "solve" this, but relying on such bugs is not exactly the best idea. Corresponding to flashrom svn r889.

* Matching board via DMIMichael Karcher2010-01-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a board is not uniquely identifiable by PCI device/subsystem IDs, a string can be specified to be looked for (case-sensitive, substring or anchored) for now in one of the following DMI items in addition to matching the PCI IDs: - System Manufacturer - System Product Name - System Version - Baseboard Manufacturer - Baseboard Product Name - Baseboard Version Strings are anchored re-like (^ at the beginning, $ at the end), but there are no plans to support full regular expressions and matched to any of the mentioned fields. The match is only made if DMI info is available and the string matches. If no DMI info is available and the PCI IDs match, a warning is printed as the board can not be autodetected. It's still open to discussion whether we add an DMI override switch to specify a string that will definitely match, and whether this switch is only used if no DMI is available or whether it overrides or augments DMI data. DMI data is currently read using dmidecode. This tool is available for all major platforms except MacOS X. I heard that there also is a MacOS X version of dmidecode, but didn't investigate that.

Note: Either internal or dummy programmer needs to be compiled in due to the current behaviour of always picking a default programmer if -p is not specified. Picking an arbitrary external programmer as default wouldn't make sense. Build and runtime tested in all 1024 possible build combinations. The only failures are by design as mentioned above.

* Use common jedec functionality where appropriateMichael Karcher2009-11-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The deleted function in en29f002a.c is reintroduced as write_by_byte_jedec in jedec.c as it contains no chip-specific instructions. It is not yet used in other chip drivers, as key addresses (0x2AAA/0x5555) are often specified with less bits. After crosschecking datasheets, most of the fixmes can probably be resolved as indicated in them, causing significant code reduction. The common JEDEC code for bytewise programming does not program 0xFF at all. The chips that had a dedicated bytewise flash function which has been changed to write_jedec_1 thus changed flashing behaviour and the "write" test flag has been removed. This applies to: AMD Am29F002BB/Am29F002NBB AMD Am29F002BT/Am29F002NBT (TEST_OK_PREW before) AMIC A29002B AMIC A29002T (TEST_OK_PREW before) EON EN29F002(A)(N)B EON EN29F002(A)(N)T (TEST_OK_PREW before) Macronix MX29F001B (TEST_OK_PREW before) Macronix MX29F001T (TEST_OK_PREW before) Macronix MX29F002B Macronix MX29F002T (TEST_OK_PREW before) Macronix MX29LV040 Similar analysis should be performed for the read id stuff.

* Refine support for the JEDEC Software Data ProtectionMichael Karcher2009-11-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the extremely dangerous unprotect_jedec function which is not used at all within flashrom code, and renames the misleadingly named protect_jedec function to start_program_jedec. Calls to protect_jedec after flashing are removed, because a) on LPC chips, the command sent by protoct_jedec is not even in the datasheet and b) on parallel chips, the block write command issued before already contained the software protection sequence, so software protection is definitely enabled. This patch also removes two clones of protect_jedec Background: JEDEC Software Data Protection started as an optional feature, which was disabled on the first single-voltage-flash chips. The software data protection is the need to prefix a write with a magic "write enable" command, while without write protection every write access into the chip's address space modifies flash content. This magic write enable command also tells the flash chip that the programmer obviously support sending write-enable commands and turns off the "any write modifies flash content" mode. There also exist a two-command (6 writes) sequence that disables Software Data Protection completey, which should only ever be used to prepare updating with a device that can't handle software data protection.

* Add infrastructure to check the maximum supported flash size of chipsets and ↵Carl-Daniel Hailfinger2009-10-311-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mainboards The rationale is to warn users when they, for example, try to flash a 512KB parallel flash chip but their chipset only supports 256KB, or they try to flash 512KB and the chipset _does_ theoretically support 512KB but their special board doesn't wire all address lines and thus supports only 256 KB ROM chips at maximum. This has cost Uwe hours of debugging on some board already, until he figured out what was going on. We should try warn our users where possible about this. The chipset and the chip may have more than one bus in common (e.g. SB600 and Pm49* can both speak LPC+FWH) and on SB600/SB7x0/SB8x0 there are different limits for LPC and FWH. The only way to tell the user about the exact circumstances is to spew error messages per bus. The code will issue a warning during probe (which does fail for some chips if the size is too big) and abort before the first real read/write/erase action. If no action is specified, the warning is printed anyway. That way, a user can find out why probe might not have worked, and will be stopped before he/she gets incorrect results.

In addition to the NVIDIA handling code it was required to call programmer_shutdown() in a lot more places, otherwise the graphics card will be disabled in the init function, but never enabled again as the shutdown function is not called. The shutdown handling may be changed to use atexit() later. Corresponding to flashrom svn r737. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Luc Verhaegen <libv@skynet.be>

* The current ICH SPI preop handling is a hack which spews lots of warnings, ↵Carl-Daniel Hailfinger2009-09-181-4/+4
| | | | | | | | | | | | | | | | | | but still yields correct results With the multicommand infrastructure I introduced in r645, it became possible to integrate ICH SPI preopcodes cleanly into the flashrom design. The new code checks for every opcode in a multicommand array if it is a preopcode. If yes, it checks if the next opcode is associated with that preopcode and in that case it simply runs the opcode because the correct preopcode will be run automatically before the opcode.

* Store block sizes and corresponding erase functions in struct flashchipCarl-Daniel Hailfinger2009-09-051-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I decided to fill in the info for a few chips to illustrate how this works both for uniform and non-uniform sector sizes. struct eraseblock{ int size; /* Eraseblock size */ int count; /* Number of contiguous blocks with that size */ }; struct eraseblock doesn't correspond with a single erase block, but with a group of contiguous erase blocks having the same size. Given a (top boot block) flash chip with the following weird, but real-life structure: top 16384 8192 8192 32768 65536 65536 65536 65536 65536 65536 65536 bottom we get the following encoding: {65536,7},{32768,1},{8192,2},{16384,1} Although the number of blocks is bigger than 4, the number of block groups is only 4. If you ever add some flash chips with more than 4 contiguous block groups, the definition will not fit into the 4-member array anymore and gcc will recognize that and error out. No undetected overflow possible. In that case, you simply increase array size a bit. For modern flash chips with uniform erase block size, you only need one array member anyway. Of course data types will need to be changed if you ever get flash chips with more than 2^30 erase blocks, but even with the lowest known erase granularity of 256 bytes, these flash chips will have to have a size of a quarter Terabyte. I'm pretty confident we won't see such big EEPROMs in the near future (or at least not attached in a way that makes flashrom usable). For SPI chips, we even have a guaranteed safety factor of 4096 over the maximum SPI chip size (which is 2^24). And if such a big flash chip has uniform erase block size, you could even split it among the 4 array members. If you change int count to unsigned int count, the storable size doubles. So with a split and a slight change of data type, the maximum ROM chip size is 2 Terabytes. Since many chips have multiple block erase functions where the eraseblock layout depends on the block erase function, this patch couples the block erase functions with their eraseblock layouts. struct block_eraser { struct eraseblock{ unsigned int size; /* Eraseblock size */ unsigned int count; /* Number of contiguous blocks with that size */ } eraseblocks[NUM_ERASEREGIONS]; int (*block_erase) (struct flashchip *flash, unsigned int blockaddr, unsigned int blocklen); } block_erasers[NUM_ERASEFUNCTIONS]; Corresponding to flashrom svn r719.
