* Enable native 4BA instructions for Spansion 25FL256SNico Huber2018-10-031-1/+4

* flashchips: Add Spansion 25FL256S......0Nico Huber2018-10-031-0/+42
| | | | | | | | | | | | | | | | The Spansion 25SFL256S supports 4BA through an extended address register, a 4BA mode set by bit 7 of that register, or native 4BA instructions. Enable the former only for now. Unfortunately the S25SF256S uses another instruction to write the exten- ded address register. So we add an override for the instruction byte.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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].

| | | | | | | | | | | | | | | | | | | | | | | | The ENE Embedded Debug Interface (EDI) is a SPI-based interface for accessing the memory of ENE embedded controllers. The ENE KB9012 EC is an embedded controller found on various laptops such as the Lenovo G505s. It features a 8051 microcontroller and has 128 KiB of internal storage for program data. EDI can be accessed on the KB9012 through pins 59-62 (CS-CLK-MOSI-MISO) when flash direct access is not in use. Some firmwares disable EDI at runtime so it might be necessary to ground pin 42 to reset the 8051 microcontroller before accessing the KB9012 via EDI. The example of flashing KB9012 at Lenovo G505S laptop could be found here: http://dangerousprototypes.com/docs/Flashing_KB9012_with_Bus_Pirate Change-Id: Ib8b2eb2feeef5c337d725d15ebf994a299897854 Signed-off-by: Mike Banon <mikebdp2@gmail.com> Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-on: https://review.coreboot.org/23259 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>

* spi25: Revise decision when to enter/exit 4BA modeNico Huber2018-01-021-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of arbitrarily deciding whether to enter 4BA mode in the flash chip's declaration, advertise that entering 4BA mode is supported and only enter it if the SPI master supports 4-byte addresses. If not, exit 4BA mode (the chip might be in 4BA mode after reset). If we can't assure the state of 4BA mode, we bail out to simplify the code (we'd have to ensure that we don't run any instructions that can usually be switched to 4BA mode otherwise). Two new feature flags are introduced: * FEATURE_4BA_ENTER: Can enter/exit 4BA mode with instructions 0xb7/0xe9 w/o WREN. * FEATURE_4BA_ENTER_WREN Can enter/exit 4BA mode with instructions 0xb7/0xe9 after WREN. FEATURE_4BA_SUPPORT is dropped, it's completely implicit now. Also, draw the with/without WREN distinction into the enter/exit functions to reduce code redundancy.

* 4BA: Support for new direct-4BA instructions + W25Q256.V updateBoris Baykov2017-10-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
