* 4BA: Add spi_exit_4ba function to switch SPI flash to 3-byte addressingEd Swierk2017-10-151-0/+2

* 4BA: Support for new direct-4BA instructions + W25Q256.V updateBoris Baykov2017-10-151-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Large flash chips usually support special instructions to work with 4-bytes address directly from 3-bytes addressing mode and without do switching to 4-bytes mode. There are 13h (4BA Read), 12h (4BA Program) and 21h,5Ch,DCh (4BA Erase), correspondingly. However not all these instructions are supported by all large flash chips. Some chips support 13h only, some 13h,12h,21h and DCh, but not 5Ch. This depends on the manufacturer of the chip. This patch provides code to use direct 4-bytes addressing instructions. This code should work but it tested partially only. My W25Q256FV has support for 4BA_Read (13h), but doesn't have support 4BA_Program (12h) and 4BA_Erase instructions. So, direct 4BA program and erase should be tested after.

* 4BA: Support for 4-bytes addressing via Extended Address RegisterBoris Baykov2017-10-151-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some flash chips data with addresses more than 24-bit field can address may be accessed by using Extended Address Register. The register has 1-byte size and stores high byte of 32-bit address. Then flash can be read from 3-bytes addressing mode with writing high byte of address to this Register. By using this way we have access to full memory of a chip. Some chips may support this method only. This patch provides code use Extended Address Register.

* 4BA: Basic support for 4-bytes addressing mode extensionsBoris Baykov2017-10-141-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If flash chip is switched to 4-bytes addressing mode then all read/erase/program instructions will be switched from 3-bytes mode to 4-bytes mode. Then well known instructions like 03h (Read), 02h (Program) and 20h,52h,D8h (Erase) will become one byte longer and accept 4-bytes address instead of 3-bytes. This patch provides support for well known instructions in 4-bytes addressing mode. Also here is the code to enter 4-bytes addressing mode by execute the instruction B7h (Enter 4-bytes mode).

* Unify non-shifted and shifted JEDEC accessCarl-Daniel Hailfinger2014-08-081-6/+0
| | | | | | | | | | | | | | | | | | Some Parallel bus chips have a 16-bit mode and an 8-bit mode. They use normal JEDEC addresses for 16-bit mode and shifted addresses (by 1 bit) for 8-bit mode. Some programmers can access them in 16-bit mode, but on all flashrom-supported programmers so far, we access them in 8-bit mode. This means we have to shift the addresses but apart from the addresses we can share the code. This patch makes this possible by checking the chip's FEATURE_ADDR_SHIFTED flag in common JEDEC functions and applying the right addresses respectively. Corresponding to flashrom svn r1840.

* Fix unlocking function for most Atmel AT2[56]D* chipsStefan Tauner2013-06-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | I broke unlocking them correctly in r1635 while refactoring (NB: the commit log including the overly selfconfident statement about the "bug in spi_disable_blockprotect_at25df()"). Affected chips have per sector protection bits and the write protection bits in the status register do indicate if none, some or all sectors are protected. It is possible to globally (un)lock all sectors at once but in a way that was not anticipated when refactoring the spi25 unlocking functions into spi_disable_blockprotect_generic(). To globally unprotect not only the protection bits (2 and 3) have 0 to be written to them but also bits 4 and 5 which normally would not be touched by spi_disable_blockprotect_generic(). Some of the chips also support a permanent lockdown with fuses which we do not handle yet. To fix this without copying the whole method I introduce another mask parameter to spi_disable_blockprotect_generic() namely unprotect_mask. See verbose comments inline for details. Also, prettyprint the status register after trying to disable the block protection fails. Corresponding to flashrom svn r1679.

* 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.

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

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