[Ltib] Re: Enable mtdparts command at u-boot prompt

[Stuart Hughes]

Hi Vijay,

Without a board/BSP it's hard to say.  I can't think why Freescale would 
have disabled this.  Have you sent a report request, they may be able to 
help? if they do can you post a conclusion to this to help out others.

FWIW, you don't need the bootloader to defined this (although it's a 
possibly a convenience).  Make sure your kernel has the right MTD 
options enabled (is it physmap support?).  Anyhow if you have this, you 
can pass your partitioning scheme on the command line using (adjust for 
your case):
 mtdparts=phys_mapped_flash:384k(uboot)ro,2M(kernel)ro,5760(jffs2)

take a look at: config/platform/mpc8349itx/deployment_instructions.txt 
for example.

Regards, Stuart
