Command line partition support in 2.6
Greetings
I'm just moving from a 2.4 to 2.6 kernel and am trying to make sense of the command line partition support. In 2.4 I added a definition in maps/physmap.c
struct map_info physmap_map = {
.name = "asif",
.size = CONFIG_MTD_PHYSMAP_LEN,
.buswidth = CONFIG_MTD_PHYSMAP_BUSWIDTH,
.phys = CONFIG_MTD_PHYSMAP_START,
};
and used a kernel command line of the form:
mtdparts=asif:64K(param),3008K(jffs),256K(u-boot),-(kernel)
to partition the flash.
What is the equivalent procedure now? All the documentation seems to skim over NOR straight into NAND and all the example maps I've looked at use a fixed partition map rather than a command line one.
I'm sure its really simple but it beats me at the moment!!
Cheers

Took me a day but at last I found the '.0' that was being stuck on the end of the physmap-flash string as the mtd-id. Duh.
Is there a way of creating an id without the '.<num>' extention so I can keep some bootloader compatability twixt 2.4 & 2.6 kernels?
