[microblaze-uclinux] DeviceTree build questions

[steve@xxxxxxxxxxxxxxx]

Hello list,

I've been looking into making the leap to a DeviceTree / Open Firmware 
2.6.30 kernel and have ended up in a maze of twisty passages, all alike.

Some questions to aid my escape:

* Are there plans to support compilation of a DT blob into the kernel, as 
  powerpc does?  

* I can't get my DTS file to build without the following changes.
  Can you confirm that these are cut-and-paste errors?

* I also can't build if the u-boot BSP is present:

    Calling uboot_v4_00_c ::generate
    #--------------------------------------
    # uboot BSP generate...
    #--------------------------------------
    System bus for instruction and data 
    ERROR main_memory not specified. Please specific main_memory
    FLASH doesn't exists
    ERROR:MDT - top () - can't read "eram_base": no such variable
           while executing
       "llength $eram_base"
           (procedure "uboot_intc" line 343)
    ...

  I don't need to do this if I can get the DT blob into the kernel,
  so I'm less worried about it.

Thanks in advance for any help.
