Hi,

I'm porting u-boot to a Moxa UC7420 box. This device uses two 16Bit Intel CFI 28F128 (16MB) flashes on CS0 and CS1. Both devices have adjected address space and used as a single logical unit of 32MB from linux.

In u-boot the CFI driver detects them as two banks each 16MB.

The root partition is starting on the first flash and ends somewhere on the second being about 30MB in size.

The mtdparts command doesn't like this setup.

I tried disabling the common CFI driver, and fake-aranged a single flash bank setup. Now mtdparts works perfect, but I have to use the board supplied flash stubs and add special handling for the baseaddress selection of some CFI commands. Right now this is really unsatisfying.

Is there some proposed and recommended way to configure u-boot for such a setup? Is there a way to map two adjected flash chips to a single mtd-dev name?

Regards Carsten
