Hi all, this patchset introduces crypto acceleration support for the crypto engine available in S3C64XX and S5PC100 SoC's. I only have access to a S3C6410 board so it would be nice if people could test these patches on S5PC100. The driver currently only supports AES and (T)DES in PIO mode, but even then it doesn't always succeed the DES self-tests so the driver part of this patch is more an RFC than an actual patch. AES seems to work better than (T)DES, but it hangs on 64-bytes transfers (DES hangs on a 24-byte transfer). There is support for DMA in the driver, but that has its own set of problems (it can't even finish a single transfer). I've tagged the patches I think are worthy for upstreaming with [PATCH], the others are tagged with [RFC] (reviews are welcome!). I'm not completely sure about my approach of handling the subsystems' register offsets currently as this limits the driver to S3C64XX- or S5PC100-only. Mapping these to virtual space could solve this and would have the benefit of reducing the ~11MB IO space on S3C64XX SoC's.
