Hi Ben,
      When i try to boot my MPC8640D based target on 2.6.30 kernel. My
target is having 1GB of RAM and 256 MB of Flash memory. I am passing the
partition information using OF Tree. During MTD subsystem initialization,
the following error message is displayed. "vmap allocation for size
268435456 failed". i found that this is due to ioremap failure which is
happening during the time of MTD initializtion.

Even thoogh HIGH_MEM support was enabled on the kernel, this is failing. 

Any configurations that need to be modified for this. 

I am using ELDK-4.0 for compilation.

Thank you
T.
