* Rename programmer registration functionsCarl-Daniel Hailfinger2014-07-191-2/+2
| | | | | | | | | | | | Register_programmer suggests that we register a programmer. However, that function registers a master for a given bus type, and a programmer may support multiple masters (e.g. SPI, FWH). Rename a few other functions to be more consistent.

| | | | | | | | | | | | | | | | Currently spi_aai_write() is implemented without an abstraction mechanism for the programmer driver. This adds another function pointer 'write_aai' to struct spi_programmer, which is set to default_spi_write_aai (renamed spi_aai_write) for all programmers for now.

* Fix parallel-style programmer access from ITE IT87/Winbond W83627 SPICarl-Daniel Hailfinger2012-03-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The ITE IT87 SPI driver uses a trick to speed up reading and writing: If a flash chip is 512 kByte or less, the flash chip can be completely mapped in memory and both read and write accesses are faster that way. The current IT87 SPI code did use the parallel programmer interface for memory mapped reads and writes, but that's the wrong abstraction. It has been fixed to use mmio_read*/mmio_write* for that purpose. The Winbond W83627 SPI driver uses the same trick in its read path for all supported chip sizes. Fix it the same way. Switch internal_chip_readn to use mmio_readn as proper abstraction. Kudos to Michael Karcher for spotting the bugs.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | Struct flashchip is used only for the flashchips array and for operations which do not access hardware, e.g. printing a list of supported flash chips. struct flashctx (flash context) contains all data available in struct flashchip, but it also contains runtime information like mapping addresses. struct flashctx is expected to grow additional members over time, a prime candidate being programmer info. struct flashctx contains all of struct flashchip with identical member layout, but struct flashctx has additional members at the end. The separation between struct flashchip/flashctx shrinks the memory requirement of the big flashchips array and allows future extension of flashctx without having to worry about bloat.

Also initially start with no busses supported, and switch to the default non-SPI only for the internal programmer. Also this patch changes the initialization for the buses_supported variable from "everything-except-SPI" to "nothing". All programmers have to set the bus type on their own, and this enables register_spi_programmer to just add the SPI both for on-board SPI interfaces (where the internal programmer already detected the other bus types), as well as for external programmers (where we have the default "none").

* Add support for more than one Super I/O or EC per machineCarl-Daniel Hailfinger2011-04-271-55/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | Flashrom currently only supports exactly one Super I/O or Embedded Controller, and this means quite a few notebooks and a small subset of desktop/server boards cannot be handled reliably and easily. Allow detection and initialization of up to 3 Super I/O and/or EC chips. WARNING! If a Super I/O or EC responds on multiple ports (0x2e and 0x4e), the code will do the wrong thing (namely, initialize the hardware twice). I have no idea if we should handle such situations, and whether we should ignore the second chip with identical ID or not. Initializing the hardware twice for the IT87* family is _not_ a problem, but I don't know how well IT85* can handle it (and whether IT85* would listen at more than one port anyway).

This means any drivers with MMIO access will _not_ suddenly start working on big endian systems, but with this patch everything is in place to fix them. Compilation should work on all architectures listed above for all drivers except nic3com and nicrealtek which require PCI Port IO which is x86-only for now. To compile without nic3com and nicrealtek, run make distclean make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no Thanks to Misha Manulis for testing early versions of this patch on PowerPC (big endian) with the satasii programmer. Thanks to Segher Boessenkool for design review and for helping out with compiler tricks and pointing out that we need eieio on PowerPC. Thanks to Vladimir Serbinenko for compile testing on MIPS (little endian) and PowerPC (big endian) and for runtime testing on MIPS (little endian). Thanks to David Daney for compile testing on MIPS (big endian). Thanks to Uwe Hermann for compile and runtime testing on x86_64. DO NOT RUN FLASHROM ON NON-X86 AFTER APPLYING THIS PATCH! This patch only provides the infrastructure, but does not convert any drivers, so flashrom will compile, but it won't do the right thing on non-x86 platforms.

* SuperI/O detection now happens unconditionally and before the chipset enableCarl-Daniel Hailfinger2009-12-221-11/+53
| | | | | | | | | | | | | | | We could run it after chipset enable, but it definitely has to happen before board enable because the board enable usually accesses the SuperI/O. With this patch, it is possible to add a struct superio to the board enable table for more accurate matching in case subsystem IDs are ambiguous.

* This is a patch which stores eraseblock sizes and corresponding block erase ↵Carl-Daniel Hailfinger2009-09-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functions in struct flashchip 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.

* Standardize on using __func__ instead of __FUNCTION__Uwe Hermann2009-09-021-2/+2
| | | | | | | | | | | | | | | The __func__ variant is standardized in C99 and recommended to be used instead of __FUNCTION__ in the gcc info page. Only _very_ old versions of gcc did not know about __func__, but we've been using both __func__ and __FUNCTION__ for a long while now, and nobody complained about this, so all our users seem to use recent enough compilers.

* Add SPI multicommand infrastructureCarl-Daniel Hailfinger2009-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some SPI opcodes need to be sent in direct succession after each other without any chip deselect happening in between. A prominent example is WREN (Write Enable) directly before PP (Page Program). Intel calls the first opcode in such a row "preopcode". Right now, we ignore the direct succession requirement completely and it works pretty well because most onboard SPI masters have a timing or heuristics which make the problem disappear. The FT2232 SPI flasher is different. Since it is an external flasher, timing is very different to what we can expect from onboard flashers and this leads to failure at slow speeds. This patch allows any function to submit multiple SPI commands in a stream to any flasher. Support in the individual flashers isn't implemented yet, so there is one generic function which passes the each command in the stream one-by-one to the command functions of the selected SPI flash driver.
