Vexpress mtdparts question

I am trying to map the nor flash on the Versatile Express platform to an mtd partition. I have tried a bunch of variations with the kernel command line "mtdparts" directive, without success.

Here is the last one I tried: mtdparts=armflash-1.0:1M(uboot),9M(linux),16M(uInitrd)

The kernel seems to detect the flash parts correctly: ... armflash-0: Found 2 x16 devices at 0x0 in 32-bit bank Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Using buffer write method Using auto-unlock on power-up/resume cfi_cmdset_0001: Erase suspend on write enabled armflash-1: Found 2 x16 devices at 0x0 in 32-bit bank Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Intel/Sharp Extended Query Table at 0x010A Using buffer write method Using auto-unlock on power-up/resume cfi_cmdset_0001: Erase suspend on write enabled Concatenating MTD devices: (0): "armflash-0" (1): "armflash-1" into device "armflash" RedBoot partition parsing not available ...

$ cat /proc/mtd dev: size erasesize name <nothing listed>

Any ideas?

Thanks, Matt
