* Rename programmer registration functionshailfinger2014-07-191-19/+19
| | | | | | | | | | | | | 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.

* Have all programmer init functions register bus masters/programmershailfinger2011-12-201-50/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | All programmer types (Parallel, SPI, Opaque) now register themselves into a generic programmer list and probing is now programmer-centric instead of chip-centric. Registering multiple SPI/... masters at the same time is now possible without any problems. Handling multiple flash chips is still unchanged, but now we have the infrastructure to deal with "dual BIOS" and "one flash behind southbridge and one flash behind EC" sanely. A nice side effect is that this patch kills quite a few global variables and improves the situation for libflashrom. Hint for developers: struct {spi,par,opaque}_programmer now have a void *data pointer to store any additional programmer-specific data, e.g. hardware configuration info. Note: flashrom -f -c FOO -r forced_read.bin does not work anymore. We have to find an architecturally clean way to solve this.

* Use struct flashctx instead of struct flashchip for flash chip accesshailfinger2011-12-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Remove the array spi_programmer, replace it by dynamic registration instead. 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").

This can be done with the "select_bbs.sh" script (Install iotools at http://code.google.com/p/iotools/ before using select_bbs). - It is very important to disable power management daemons before running flashrom on this EC. I commented out the brute force method we use in the Chromium OS branch that disables powerd, since IIRC Carl-Daniel has a better approach in the works. - Due to dependencies which may be introduced by the OEM/ODM EC firmware, the code is not guaranteed to work for anything other than the Cr-48.

* Add support for the Open Graphics Project development card, OGD1, as ahailfinger2010-12-031-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPI flash programmer. The project is in the the process of designing and making a complete, open source, graphics card. More info at http://wiki.opengraphics.org. The first development card is a PCI add in card containing a couple of FPGAs and a couple of serial flash chips (amongst other things). The FPGAs are called XP10 and S3 (their part numbers). The XP10 contains its own flash and does not need to be programmed by flashrom - it ensures that the device can enumerate on the PCI bus without needing further configuration. The larger FPGA is the S3. This is configured from a large SPI flash (2 MBytes). The second SPI flash is used to store the VGA BIOS. It is smaller (128 KBytes). This patch adds support for programming either of the two SPI flash chips. The programmer device takes one configuration option which selects which of the two flash chips is accessed. This must be set to either "cprom" or "bprom". (The project refers to the two chips as "cprom" / "bprom", "s3" and "bios" are more readable alternatives). Add support for SST SST25VF010 (REMS).

* Honor ICH SPI address window for reads.hailfinger2010-09-151-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | ICH SPI has the ability to restrict SPI read/write accesses to a given address range. The low end of the range is configurable by the BIOS (and by flashrom if the BIOS didn't lock down the flash interface), the high end of the range is 0xffffff (2^24-1). This patch checks for an address range restriction and uses the low end of the allowed range as base for SPI reads. A similar workaround for REMS/RES opcodes has been committed in r500. This fixes read on the Intel D945GCLF mainboard where the stock BIOS enforces a restricted address range.

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!

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.
