- A general remark : instead of using SPARC_IOMMU_TRANSLATE, you should use
new memory helpers to read or write bytes such as
pcnet_physical_memory_read() and pcnet_physical_memory_write(). The
rationale is that ultimately pci memory accesses will also use PCI specific
I/Os to handle the case where the PCI memory is not mapped directly in the
CPU address space. For the sparc iommu you should define global helpers
such as sparc_iommu_memory_read() and sparc_iommu_memory_write().
Something like this?
