Q127C and Q128C are not the same. Q127C doesn't support QPI but Q128C does. So we need to split the existing GD25Q127C/GD25Q128C into two separated entries. We also introduce the new flashchip Q128E and merge it into Q127C. Datasheets: Q128E: https://www.gigadevice.com.cn/Public/Uploads/uploadfile/files/20220714/DS-00480-GD25Q128E-Rev1.2.pdf Q127C: https://www.gigadevice.com.cn/Public/Uploads/uploadfile/files/20220714/DS-00220-GD25Q127C-Rev2.3.pdf Q128C: https://www.endrich.com/sixcms/media.php/2/GD25Q128C-Rev2.pdf Q128E and Q127C/Q128C have compatible main functions, their differences are: * Q128E uses 55 nm process, while Q127C/Q128C use 65nm * Q128E/Q127C does not support QPI * Q128E/Q127C have OTP: 3072B, while Q128C are 1536B * Q128E's fast read clock frequency is 133MHz, while Q127C/Q128C are 104MHZ So we decided to merge Q128E into Q127C. We also tested that Q128E could pass flashrom_tester while probing it as 127C/128C, so the main functionalities are compatible. Change the chip name from GD25Q127C/GD25Q128C to two entries GD25Q127C/GD25Q128E and GD25Q128C to make it more accurate. Chip revision history: - The 'GD25Q127C/GD25Q128C' definition was added in `commit e0c7abf219b81ad049d09a4671ebc9196153d308` as 'GD25Q128C' and later renamed to 'GD25Q127C/GD25Q128C' BUG=b:304863141, b:293545382 BRANCH=none TEST=flashrom_tester with flashrom binary could pass with Q128E, which contains probe, read, write, erase, and write protect Signed-off-by: Hsuan Ting Chen <roccochen@google.com> Change-Id: I3300671b1cf74b3ea0469b9c5a833489ab4914f5 Reviewed-on: https://review.coreboot.org/c/flashrom/+/78348 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Anastasia Klimchuk <aklm@chromium.org>
flashrom README
===============
flashrom is a utility for detecting, reading, writing, verifying and erasing
flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images
in-system using a supported mainboard, but it also supports flashing of network
cards (NICs), SATA controller cards, and other external devices which can
program flash chips.
It supports a wide range of flash chips (most commonly found in SOIC8, DIP8,
SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various
protocols such as LPC, FWH, parallel flash, or SPI.
Do not use flashrom on laptops (yet)! The embedded controller (EC) present in
many laptops might interact badly with any attempts to communicate with the
flash chip and may brick your laptop.
Please make a backup of your flash chip before writing to it.
Please see the flashrom(8) manpage :doc:`classic_cli_manpage`.
