Re: [flashrom] [PATCH 3/6] changes macros for SSFS and SSFC bits: - introduce mask macros - add comments - change SSFS_CDS to SSFS_FDONE (abbr. used in datasheet not in SSFS but HSFS) - use those for refactoring and magic number elemination. - following patch uses them for pretty printing

If both are needed. It would be nicer to get rid of either.

I have Asus L1N64WS/B (SST49LF080A) and L1N64WS-Sli (Winbond W39V080APZ) motherboards. It's not supported by flashrom I attached the dmi output and an "lspci -vvnnxxx" output. ---------- Forwarded message ---------- From: Julian Shulika <hercares(a)gmail.com> Date: 2011/3/29 Subject: Re: [flashrom] Asus L1N64WS/B To: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at>

One more student would like to participate in GSoC
by Tadas Slotkus 04 Apr '11

04 Apr '11

Hello, I am a student at Kaunas University of Technology in Lithuania, studying Informatics Engineering second course and I would love to participate in GSoC. I have received some datasheets from VIA for unsupported chipsets, I would like port them. I have good soldering skills and am able to make small printed circuit boards. Some of my homemade art PCBs: http://www.papile.projektas.lt/imgs/usb/ So I have to setup a convenient flashing system for future development which would be brick unaware. I am interested in these ideas: 1) flashrom remote flashing with modified SerialICE - needs to add flashing functionality. With SerialICE we won't need RAM working, so it will help developing chipset code. After reset SerialICE flashing part will be activated with dosens of bytes receiveid through serial port, and communication with HOST system will be initiated (HOST system then will send commands for flashing). If SerialICE won't get any bytes from serial port in a few milliseconds it will let the coreboot to run. We would use flashrom's codebase for flashing protocols... 2) flashrom as payload - for such implementation we should make a config system where we would choose which flash chip(s) are needed to be included in our payload's build. The rom image might be transferred through serial port. But payload needs RAM, so this idea is in discussion list. The first idea would be the primary objective for me. What do you think? Thanks, Tadas Slotkus P.S. I have been around coreboot for some time. My earlier email in mailing-lists: mrtadis(a)gmail.com, current irc nick: mrtadis)
