[U-Boot-Users] MTD Concat support

[Luigi 'Comio' Mantellini]

Hi Guys,

I'm a question regarding the MTD Concat support in U-BOOT.
My system has 2 Flash (x16MB) driven by 2 different Chipselects. The
memory layout is the following:

[0xbe000000 -> 0xbeffffff ] Flash#0 CS#0
[0xbf000000 -> 0xbfffffff ] Flash#1 CS#1

I would link to create a JFFS2 partition across the two flash banks with size about 28M. In other hands I should meet the following partition layout:

[0xbe000000 -> 0xbfc00000 ] JFFS2 root 
[0xbfc00000 -> 0xbfe00000 ] U-BOOT code
[0xbfe00000 -> 0xbfffffff ] DATA

Into the JFFS2 filesystem there are the Kernel images and a lot of spare datas.

How I can say to U-boot to consider the two flashes as a single space of
memory (in order to place a big JFFS2 filesystem)? In Linux I can
achieve this using the MTD Concat driver but I don't understand How I
can do in U-boot.

Thanks a lot for any comments.


ciao

luigi
