* spi25_statusreg.c: restore SR contents at flashrom exitNikolai Artemiev2021-01-131-0/+9
| | | | | | | | | | | | | | register_chip_restore() provides a general mechanism for restoring a chip's state at flashrom exit; it can be used whenever the SR needs to be changed temporarily to perform some operation and changed back after the operation is complete. The only current current use case is in s25f.c, which changes the SR's sector layout bits so that entire flash accessible. This patch uses the chip restore functionality to reset changes to the status register made by spi_disable_blockprotect_generic(). This should help to ensure consistency across multiple runs of flashrom and make it easier to predict how a specific operation will change the flash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hardware write protect is applied, flashrom crashed and generate coredump. spi_disable_blockprotect_generic() calls flash->chip->printlock() method when disable was failed, but this method is optional, can be NULL depends on type of flashrom chip. NULL pointer check before call is added to avoid crash.

* Revert "flashchips: port S25FS(128S) chip from chromiumos"Nico Huber2020-05-011-86/+0
| | | | | | | | | | | | | | | | | | | | | This reverts commit a3519561bd0fb44153bb376322b799000657576f. Breaks support for most SPI flash chips. It's too big and too invasive to be reviewed as a single commit. The changes to `spi_poll_wip():spi25.c` were not noticed in the original review that were from the similarly named function and file `s25f_poll_status():s25f.c` in the downstream Chromium fork. V.2: Rebase and rephrase commit msg to reflect how the issue slipped in.

* const'ify flashctx to align signatures with cros flashromEdward O'Callaghan2020-04-301-3/+3
| | | | | | | | | | | | | | | | The ChromiumOS flashrom fork has since const'ify flashctx in a few places. This aligns the function signatures to match with downstream to ease forward porting patches out of downstream back into mainline flashrom. This patch is minimum viable alignment and so feedback is welcome.

* flashchips: port S25FS(128S) chip from chromiumossibradzic2020-04-221-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This may seem too big just to support yet another flash chip, but in reality it brings support for whole new family of S25FS Spansion/Cypress flash chips. These chips require handling of some special status registers for erasing or writing, with very specific timing checks in place. For example, WIP status bit will remain being set to 1 if erase or programming errors occur, and in that case chip 'software reset' has to be performed otherwise the chip will remain unresponsive to all further commands. Also, special CR3NV register (Configuration Register 3 Nonvolatile) status bits needs to be read and set by using RDAR (ReaD Any Register) and WRAR (WRite Any Register) OP commands, and these states are needed to determine which type of reset feature is enabled at the time (legacy or S25FS type) in the first place, determine whether Uniform or Hybrid sector architecture is used at the time, or set programming buffer address wrap point (256 or 512 bytes). Furthermore, S25FS chip status register has to be restored to its original state (hence that ugly CHIP_RESTORE_CALLBACK) following erasing or writing, failing to do so may result in host being unable to access data on the chip at all. Finally, although this brings support for the whole family of chips, I only have one such chip to do the actual testing, S25FS128S (Small Sectors), which I had fully tested on ch341a and FT4232H programmers, with confirmed working probe, read, erase and write. Full summary of changes are here: flashchips: add new flashchip sctructure property: .reset add chip definitions: S25FS128S Large Sectors S25FS128S Small Sectors flash: add macro (chip_restore_func_data call-back): CHIP_RESTORE_CALLBACK flashrom: add struct: chip_restore_func_data add call-back function: register_chip_restore spi: add OP codes: CMD_RDAR, CMD_WRAR, CMD_WRAR_LEN, CMD_RSTEN, CMD_RST add register bit function definitions: CR3NV_ADDR, CR3NV_20H_NV add timers: T_W, T_RPH, T_SE spi25: refactor (based on chromiumos implementation) function: spi_poll_wip port these functions from chromiumos: probe_spi_big_spansion s25fs_software_reset s25f_legacy_software_reset s25fs_block_erase_d8 spi25_statusreg: port these functions from chromiumos: spi_restore_status s25fs_read_cr s25fs_write_cr s25fs_restore_cr3nv Most of the ported functions are originally from s25f.c found at https://chromium.googlesource.com/chromiumos/third_party/flashrom with exception of spi_restore_status which is defined in spi25_statusreg.c. The rest of macros and OP codes are defined in same files as in this commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch seems to have originally been from https://patchwork.coreboot.org/patch/4126/ . The most recent version seems to be in OpenEmbedded (commit 503a572) which added support for 16Mbit and 32Mbit variants. The OpenEmbedded patch also makes changes to linux_spi.c to add some debug prints which are omitted in this version. From the original commit message: Differences between SST26 and SST25: 1. The WREN instruction must be executed prior to WRSR [Section 5.31]. There is no EWSR. 2. Block protection bits are no longer in the status register. There is a dedicated 144-bit register [Table 5-6]. The device is write-protected by default. A Global Block-Protection Unlock command unlocks the entire memory [Section 4.1].

It was reclassified to Host Bridge in the PCI device ID database and there is at least one report suggesting this configuration too: http://www.flashrom.org/pipermail/flashrom/2012-August/009716.html - Added MCP89 which hopefully works with the code for previous versions. Thanks to James Laird for submitting this change. Tested flash chips: - Atmel AT25DF641(A) to PREW (+PREW) http://www.flashrom.org/pipermail/flashrom/2013-June/011113.html - Atmel AT25F512 to PREW (+PREW) http://www.flashrom.org/pipermail/flashrom/2013-April/010904.html Also, change its ID according to Modification of PCN SC040401A: "There has been a change in the returned value of the Product Identification (RDID) command, the AT25F512A RDID code is 65h compared to 60h from the AT25F512 product." It seems to be quite likely that all AT25F512 are fully functional relabeled AT25F1024 chips. There are even some hints in the datasheet: in table 6 they stress that address pin 16 needs to be low under all circum- stances; while continuous reads can wrap around on the AT25F1024 the DS notes "For the AT25F512, the read command must be terminated when the highest address (00FFFF) is reached." OTOH the lock bit semantics are different, but this has not been tested thoroughly - Atmel AT25F512A to PREW (+PREW) http://paste.flashrom.org/view.php?id=1569 - Eon EN25F05 to PREW (+PREW) http://paste.flashrom.org/view.php?id=1571 - Macronix MX25L12805(D) to PREW (+REW) http://www.flashrom.org/pipermail/flashrom/2013-April/010913.html - Spansion S25FL256S......0 and S25FL512S to P/!R!E!W (+P) Tested by Stefan Tauner - Micron/Numonyx/ST M25PX80 to PREW (+PREW) Tested by Stefan Tauner - Micron/Numonyx/ST N25Q032..3E and N25Q128..3E to PREW (+PREW) Tested by Stefan Tauner - Micron/Numonyx/ST N25Q256..3E and N25Q512..3G to P/!R!E!W (+P) Tested by Stefan Tauner - SST SST25VF040B to PREW (+PREW) http://paste.flashrom.org/view.php?id=1574 - SST SST25VF040B.REMS to PREW (+EW) http://paste.flashrom.org/view.php?id=1575 - ST M25P05-A to PREW (+PREW) http://paste.flashrom.org/view.php?id=1576 - ST M29W512B to PREW (+W) http://www.flashrom.org/pipermail/flashrom/2013-March/010635.html - Winbond W25Q64.W to PREW (+PREW) Tested by the chromiumos guys. - Winbond W25Q128.V to PREW (+REW) http://www.flashrom.org/pipermail/flashrom/2013-June/011108.html - Winbond W25X20 to PREW (+PREW) http://www.flashrom.org/pipermail/flashrom/2013-May/010990.html Miscellaneous: - Add Lenovo X201 to the laptop whitelist. - Add chip IDs for the ESMT F25L..QA family. - Add chip IDs for a few Macronix MX25 models. - The list of flashchips is not sorted strictly alphabetically and should not be either. Refine the comment explaining the scheme on top of the list. - Support -L output of chip sizes with up to 6 decimal places (up to 4 Gb). - Use z length modifier in (more) prints for size_t types. - Remove chips >16MB again because our current implementation of memory mapping the flash chip violates common rules by mapping a window as large as the chip. This leads to failing mmaps as can be seen here: http://paste.flashrom.org/view.php?id=1695 - Document spispeed parameter of linux_spi (and fix some leaks). - Rephrase the "multiple chips detected" message because it was confusing. - Skip verification step if the image is equal to the flash contents. - Tiny other stuff.

* Fix unlocking function for most Atmel AT2[56]D* chipsStefan Tauner2013-06-201-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 PMC Pm25LD seriesStefan Tauner2013-04-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | This patch adds support for - Pm25LD256C - Pm25LD512(C) - Pm25LD010(C) - Pm25LD020(C) - Pm25LD040(C) These seem to be the successors of the Pm25LV series. The main difference seems to be the dual I/O and additional erase opcodes. Some support an additional, complex locking register (maybe all of the above, but available datahsheets do not indicate it for all). The Pm25LD512C was tested by Chi Zhang: http://paste.flashrom.org/view.php?id=1579 Corresponding to flashrom svn r1671.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Tauner2012-12-291-0/+591
- 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.
