Hello everyone. Sorry for the quietness lately, I have been out straight at work implimenting a new tape library project (BRMS for those of you that know AS400's). Kind of cool working with LTO4's (1 1/2 terabites) and a tape library that can hold 110 LTO4's (IBM TS3310).
Anyways, I am going to start a project based on a very simple and CHEAP LPC flasher originally designed for the xbox. http://rex.xbox-scene.com/LPC2/LPC2.html I have a friend that has already tested this on fwh hubs (SST49LF008A to be exact) and it worked great. I have placed an order so the parts should be arriving soon. The downside is the software is only for dos/win, but the software source code is also available on the site. I think it would be pretty easy to convert it to Linux. I am trying to get a hold of the original author for permission to release it under a GPL.
My question to the coreboot community is….. I have no problem hosting this project on my site, but would everyone like me to incorporate this project into coreboot? If so is anyone interested in helping?
By the way Stefan great work on the i945!! Those Intel doors are starting to slowly creep open...

Do we want to add support for this flasher to flashrom? In theory, reusing the abstraction model present since SPI could work well.

I would be really happy to see this project associated with coreboot.
yes, stefan's work on the i945 was really groundbreaking.

flashrom support would be very very cool :-) The ability of flashrom flashing over LPC would greatly broaden it horizons. After I get it up and working, I also am going to do some testing with USB to LPC adapters for those of you that don't have a LPC port. These adapters can be found on eBay for pennies on the dollar (very cheap). I also plan on powering the LPC flasher from USB.

You mean LPT?

AFAIK most USB-LPT adaptors have timing problems (timing is important for many LPC chips) and you may not be able to control all pins manually. If it works, more power to you!

Hmm, that maybe a problem. That is off in the future anyways. But I am going to at least give it a shot :-|

By the way, there's also a homemade SPI flasher which should be way easier to support from flashrom: http://rayer.ic.cz/elektro/spipgm.htm
IIRC Rudolf mentioned it some time ago.

That's really cool for SPI but I am more interested in PLCC32 fwh chips....

FWH is virtually obsolete. At least, no one is using it for new designs. Have you seen any _new_ designs with LPC/FHW lately?
SPI NOR flash support in flashrom would be far more important for coreboot to be relevant in the future.

Yes, most Via C7-based Mini/Nano/Pico-ITX boards use LPC flash.

I'm not saying it couldn't support SPI, in fact I'm sure it probibly could. I'm just telling why I am interested in persuing this project, am what I am going to use it for. Along the lines if a modification for SPI happens, great :-)
