mapping of boot loader offset

mapping of boot loader offset

[Tino Keitel]

Hi folks,

I wonder what to do if a processor looks for its BIOS/loader at a specified
address that is somewhere in the middle of a flash chip. The same chip will
contain one JFFS2. The boot loader area will have to be mapped out of the
file system. Is there already something that MTD can do for me?

Regards,
Tino

Have a look at the dilnetpc.c map driver. It has to deal with 
exactly this situation and it does so by using the mtd concat layer.
