I am porting the board/ppmc8260/strataflash.c to my custom board, which is based on a MPC8245 with Intel 28F640J3A in 8-bit mode. The 28F640J3A can be configured as 8 bit or 16 bit wide. flash_detect_cfi() returns 16 bit portwidth (FLASH_CFI_16BIT) and 8 bit chipwidth (FLASH_CFI_BY8),

mode? Has anyone used this device in 8 bit mode and already solved the problems that I experience?
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?
Best regards,
