yes. 

I have changed ERAM_SIZE to 0x00200000 on my board to see whether
microblaze linux works with 2MiB of ram or not. the boot log i got is
some like this:

well, kmem_cache_estimate() is not for icache/dcache.  it's for slab
cache.

can you put printk in kmem_cache_estimate() to see exactly where the
kernel stoped?
