v3: -DT maintainers - please ack patch 8/8 "arm64: dts: ls1043a: add crypto node" (to go into kernel 4.8 via crypto tree) -Fixed typo in pdb.h: s/be32/__be32 -Appended Acks (from v2) into commit messages -Tested that current patch set works on top of RSA support being added by Tudor Ambarus: [PATCH v6 0/3] crypto: caam - add support for RSA algorithm https://www.mail-archive.com/linux-crypto@xxxxxxxxxxxxxxx/msg19085.html v2: As suggested by Arnd, patch 1 fixes io{read,write}{16,32}be accessors to prevent the case when {read,write}{w,l} are overriden by arch-specific ones having barriers, while the BE accessors previously mentioned are not (thus behaving differently, having no barriers). Hi, [Patches 2-4 add io{read,write}64[be] accessors (generic, arm64, ppc64), such that CAAM's accessors in regs.h are simplified a bit. Patch 8 adds crypto node for LS1043A platform. Let me know if it's ok to go with these through the cryptodev-2.6 tree.] This is a follow-up on the following RFC patch set: crypto: caam - Revamp I/O accessors https://www.mail-archive.com/linux-crypto@xxxxxxxxxxxxxxx/msg15878.html There are platforms such as LS1043A (or LS1012A) where core endianness does not match CAAM/SEC endianness (LE vs. BE). Add support in caam driver for these cases. Current patch set detects device endianness at runtime (as opposed to compile-time endianness), in order to support multiplatform kernels. Detection of device endianness is not device-tree based. Instead, SSTA ("SEC STAtus") register has a property such that reading it in any endianness and masking it properly, it's possible to deduce device endianness. The performance drop due to the runtime detection is < 1.0%. (An alternative implementation using function pointers has been tried, but lead to a bigger performance drop.)
