RE: [U-Boot-Users] Intel Strataflash in 8-bit mode
All the drivers are derived from my original strataflash driver. There is a problem with 8bit wide detection in the flash_cfi_detect routine. The work around is to hardcode the port width after flash_cfi_detect is called. I believe I understand the problem, but I have no access to 8bit hardware. If some one is willing to help debug the problem with 8 bit wide protection, I will take on fixing the strataflash driver and moving it to the drivers directory. This driver does include support for 64 bit wide flash and access to the write once areas. Is anyone willing and able to work with me? Brad

You may notice that there are three (3 !!!) other implementations of the very same driver in the U-Boot source tree:
board/esd/cpci440/strataflash.c board/esd/pmc405/strataflash.c board/ppmc8260/strataflash.c board/zpc1900/flash.c
Maybe we should make an attempt and clean up this mess a bit?
Stefan, two of these files are in your realm - do you have any resources available to take the lead?
Sorry, no time and no hardware at the moment!
Ciao, Stefan.

Dear Brad,

Thanks for volunteering.

I don't have any systems here in 8 bit mode, sorry.
Best regards,

Brad,
Unfortunately, I don't have 8 bit strataflash. I can't help there.
I looked at your driver for Cogent CSB272 board intially but it does not seem to support 2x 16-bit strataflash on a 32bit bus either.
I can help you with the driver to add such support as well. I agree a unified flash driver that is capable of handling various bus and port widths is probably a good thing. Few boards if any have odd ball configurations that need a custom driver. Most newer flash are CFI compliant.
