I wonder if it doesn't make more sense to use the Linux MTD framework. I have begun porting devbios to it. I have refactored devbios into two halves, devbios and a flash library/map library. The MTD chip driver which uses the library is about half done.
Perhaps then the LinuxBIOS flash tool can be split into a map driver (the shadow control stuff) and a chip driver for the individual flash chips, then included into MTD.
Regards,
Jeremy
PS - I've used Uniflash, it's very old code with lots of nice global variables and such, but it did help me get an Atmel flash chip working.

Hello guys!
Yesterday I spent the day fighting the flash_rom on my pcchips m787cl+ board (SiS630). It just won't work. It mmaps correctly and I can read the BIOS (i created a flash_save tool based on the flash_rom.c code), but the chip identification just doesn't work. My assumption is that it doesn't disable Shadow memory before sending the SoftID sequence to the flash. Btw, the 'flash_and_burn' thing simply doesn't compile complaining on the absence of the 'pci/pci.h' file. So I use flash_rom.c from the 'sis630' directory.
But that was just a preface. What I was going to say here is after I gave up fighting with the flash_rom.c, I started searching the Internet for universal flash writers. And you know what? I found a marvelous tool - Uniflash! It can flash almost any flash part on almost any motherboard with any file you say. The tool is written in Pascal for DOS and is open source. I think those of you here who are into the development of the flash_rom.c can use that source to make flash_rom.c way more compatible than it is now.
For now I prefer using Uniflash from DOS. It made my m787cl+ boot LinixBIOS in less than a minute after I spent the day fighting the flash_rom.c :))))
