Hello Anastasia Klimchuk, Nikolai Artemiev, Stefan Reinauer, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/78348?usp=email
to look at the new patch set (#6).
Change subject: flashchips: Split GD25Q127C/GD25Q128C and add GD25Q128E ......................................................................
flashchips: Split GD25Q127C/GD25Q128C and add GD25Q128E
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-00... Q127C: https://www.gigadevice.com.cn/Public/Uploads/uploadfile/files/20220714/DS-00... 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
