I am programming ohci driver for my arm7 based on 2.6.38.
td_alloc -> dma_pool_alloc -> dma_alloc_coherent().
In previous uclinux version, there is the consistent.c located in
arch/armnommu/mm to implement
this dma_alloc_coherent, but now this latest version, I did not see
this 'dma_alloc_coherent' function
for armnommu, so I can use this function directly like this arm mmu?
Yes. There is no separate one for the nommu case. It just
uses the standard one in arch/arm/mm/dma-mapping.c.
In addtion, the 'kmalloc' is the same to previous uclinux armnommu
version? I can use it directly?
Oh, yes. There is no changes in how that works.

Greg
