Just do it, then.
Is there a good method of setting up two flash devices at once? As
Yes, U-Boot has always been capable of doing this. Your flash devices will form spearate "banks" of flash memory. Thee is no requirement that all banks must be identical. In fact, several boards use different flash types on different banks.
far as I can tell, all the flash functions (like flash_print_info, for example) can only be defined for one type of flash at a time.
You are wrong.
There are two solutions I have thought of so far. One of them is pick whichever flash device is used the most and set that up normally. For the other flash, I could create different functions for it and in the
This is not accetable, and not necessary.
The other option might be to create my own flash function wrappers that call the appropriate flash function based on, for example, the address passed into the function.
You don't have to create any new interfaces. The existing code which provides a flash_info struncture per bank of flash memory is sufficient.
Has anyone else ran into this problem? Perhaps that is another board
It's not a problem. It's somthiong that is working fine on several boards.
config that already deals with this? I looked around, but there are a lot of configs and I easily could have missed what I was looking for.
See for example "board/cpu86/flash.c"
