* Add support for Atmel's AT25F series of SPI flash chipsStefan Tauner2012-12-291-0/+7
| | | | | | | | | | | | | | | | | | This adds support for the following chips: - AT25F512, AT25F512A, AT25F512B - AT25F1024, AT25F1024A - AT25F2048 - AT25F4096 Besides the definitions of the the chips in flashchips.c this includes - a dedicated probing method (probe_spi_at25f) - pretty printing methods (spi_prettyprint_status_register_at25f*), and - unlocking methods (spi_disable_blockprotect_at25f*) Corresponding to flashrom svn r1637.

* Add support for Intel S33 series flash chipsStefan Tauner2012-12-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This includes: Bottom boot block: * 16Mb/2MB: QB25F160S33B8, QB25F016S33B8, QH25F160S33B8, QH25F016S33B8 * 32Mb/4MB: QB25F320S33B8, QH25F320S33B8 * 64Mb/8MB: QB25F640S33B8, QH25F640S33B8 Top boot block: * 16Mb/2MB: QB25F160S33T8, QB25F016S33T8, QH25F160S33T8, QH25F016S33T8 * 32Mb/4MB: QB25F320S33T8, QH25F320S33T8 * 64Mb/8MB: QB25F640S33T8, QH25F640S33T8 At least some seem to be marketed by other vendors (too?) but also with Intel's vendor ID. Besides a 0xC7 chip erase and a 0xD8 uniform 64kB block erase they support also erasing the top/bottom 8 8kB blocks with opcode 0x40. But since this command fails for all addresses outside those ranges, it is not easily implemented with flashrom's current code base and hence left out. Corresponding to flashrom svn r1636.

* Improve SPI status register pretty printingStefan Tauner2012-12-291-24/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move all functions related to SPI status registers to a new file spi25_statusreg.c. This includes the generic as well as the SST-specific functions from spi25.c and the chip-specific functions from a25.c and at25.c. - introduce helper functions * spi_prettyprint_status_register_hex() * spi_prettyprint_status_register_bpl() * spi_prettyprint_status_register_plain() Use the latter on every compatible flash chip that has no better printlock function set and get rid of the implicit pretty printing in the SPI probing functions. - remove * spi_prettyprint_status_register_common() * spi_prettyprint_status_register_amic_a25lq032() because it can be fully substituted with spi_prettyprint_status_register_amic_a25l032(). * spi_prettyprint_status_register() (old switch, no longer needed) - promote and export * spi_prettyprint_status_register_amic_a25l05p() as spi_prettyprint_status_register_default_bp1(). * spi_prettyprint_status_register_amic_a25l40p() as spi_prettyprint_status_register_default_bp2(). * spi_prettyprint_status_register_st_m25p() as spi_prettyprint_status_register_default_bp3(). - add #define TEST_BAD_REW and use it for a number of Atmel chips which had only TEST_BAD_READ set even though they dont have erasers or a write function set.

* Add support for Atmel AT26DF041Stefan Tauner2012-10-271-0/+2
| | | | | | | | | | | | | | | | | | Wicked chip: No WRSR, no write enable command (but swallows our default one without a problem), supports an auto-erasing page write (but even without that page writes are recommended to write the whole page i.e. operate on a completely erased page), mad requirements on block refreshments if only partly written. Found on my Intel D946GZIS and tested with my serprog in situ. Using the page write by setting JEDEC_BYTE_PROGRAM to 0x11 and using the spi_chip_write_256 command greatly improves performance and works flawlessly. Corresponding to flashrom svn r1616.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-84/+84
| | | | | | | | | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r1316.

* Move implicit erase out of chip driversCarl-Daniel Hailfinger2010-10-081-5/+0
| | | | | | | | | | | | | | | | | | Flashrom had an implicit erase-on-write for most flash chip and programmer drivers, but it was not entirely consistent. 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. Corresponding to flashrom svn r1206.

* The SPI opcode 0xd8 is not a chip erase opcode on any chip out thereCarl-Daniel Hailfinger2010-06-201-2/+0
| | | | | | | | | | | | Besides that, the function as implemented just walks the chip and ignores sector sizes. Sector erase with SPI opcode 0xd8 is of course still supported.

| | | | | | | | | | | | Some chips implement the RES (0xab) opcode, but they use a non-standard two byte response instead of the usual one byte response. A two-byte response has the accuracy of REMS and RDID, so don't check for REMS/RDID availability before running a two-byte RES. Corresponding to flashrom svn r1017.

Create spi_write_chunked as a copy of spi_read_chunked and convert all SPI programmers to use it.
