[U-Boot-Users] supported flashes?
Hi to all,
It's the first time I write to this list. I am involved now in a new design based the MPC8272 processor. I have choosen U-boot as my booter am by now I am trying to select the flash memory, so I have to determine which are supported.
And this is not very easy, because I couldn't find any doc related to hardware support. I have looked at the code and I found lots of files about flash support. In particular:
drivers/cfi_flash.c board/mpc8260ads/flash.c common/flash.c common/env_flash.c
I have concluded that cfi_flash.c gives support for all those flashes which implements the JEDEC CFI interface with AMD or Intel command sets, and mpc8260ads/flash.c gives support for the flash in the ADS board (which is not CFI at all). Am I wrong? What about the other files? Is there anywhere a list of supported flashes?
In conclusion, can i suppose that any CFI flash with the appropriate command set will be supported by u-boot.
Thanks to all
Alex Bastos

-> generic flash driver for CFI conformant flash chips
board/mpc8260ads/flash.c
In general: board/<name>/flash.c:
-> board specific (optimized) flash driver suporting only the possible flash chip configurations on a specific board.
common/flash.c
-> common flash handling routines
common/env_flash.c
-> code to deal with saving environment variables in flash memory

See include/flash.h for a list ;-)

Yes. And a lot more.
