* Generify a25.c's SRWD printing function and move it to spi25.c.stefanct2012-09-221-5/+9

* Add spi_block_erase_62.stefanct2012-09-211-0/+47
| | | | | | | | | | | | This is used by the AT25F series (only?), but is generic enough to reside in spi25.c. The only currently supported chip is the AT25F512B. Other members of that series need some additional infrastructure code, hence this patch adds the erase function to the AT25F512B only.

* Let the programmer driver decide how to do AAI transfershailfinger2012-06-151-2/+1
| | | | | | | | | | | | | | | | | 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. A patch which utilises this abstraction in the dediprog driver will follow.

* spi25.c: Refactor spi_write_status_register helpers.stefanct2012-05-021-58/+14
| | | | | | | | | | | | | | | | | | | | | | | | | In r1115 "Write protection handling for Atmel AT25*" the old spi_write_status_register function was duplicated to send WREN and EWSR commands respectively controlled by a new common wrapper function spi_write_status_register without a reason. Both functions' resulting code is equal apart from the opcode used. The code itself does also differ in the macros used, but their value (apart from the opcode) is equal. This patch adds a new parameter for the opcode to the helper function which allows removal of the other one. This relies on the fact that EWSR and WREN have the same INSIZE and OUTSIZE though. If that is really seen as an issue, the sizes could be made parameters too. This patch also changes the wrapper so that it no longer sets the feature bits of the struct flash(ctx) argument. This may result in changed output, because it no longer implicitly disables the debug message in following executions. Since almost all chips had their feature bits fixed in the previous commit, this is a minor problem. Also, spi_write_status_enable has been dead code since r658 or so. Remove it.

* Add support for SFDP (JESD216).stefanct2012-02-171-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to modules using the opaque programmer framework (e.g. ICH Hardware Sequencing) this uses a template struct flashchip element in flashchips.c with a special probe function that fills the obtained values into that struct. This allows yet unknown SPI chips to be supported (read, erase, write) almost as if it was already added to flashchips.c.

* Have all programmer init functions register bus masters/programmershailfinger2011-12-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 accesshailfinger2011-12-141-24/+24
| | | | | | | | | | | | | | | | | | | | | | | 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.

For SPI chips the lock printing was handled by one common function, but sharing a common function which only is a big switch() statement doesn't make sense, especially if we can define lock printing functions per flash chip anyway. The printlock function pointer in struct flashchip is used to print status register and locking information, and serves as replacement for implicit status register and lock printing during probe. That code will later be changed to store locking info in a machine- accessible data structure so flashrom can handle locked regions correctly.

Some drivers had their own hand-rolled partial update functionality which made handling partial updates from generic code impossible. Move implicit erase out of chip drivers, and kill some dead erase functions at the same time. A full chip erase is now performed in the generic code for all flash chips on write, and after that the whole chip is written.

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.
