I'v been making progress on our port to a custom PPC440GX board. We
want to use the CFI driver for all U-Boot Flash operations.
Our board design uses 2 Intel 16-bit wide StrataFlash chips wired in
"parallel". But with the following defines in place, flash_init()
None of the U-Boot docs or source code describe a parallel chip
configuration, but the flash_cfi.h history entry does suggest its
support: 01/22/2004 - Write performance enhancements for parallel chips
The source also checks the status of info->interface for a value of
FLASH_CFI_X8X16. I have not yet tried setting this "interface" value.
If anyone can suggest any other settings that I should be pay attention
to, please advise.
Thank you, Andy
