The driver provides in kernel support for the Hisilicon SEC accelerator found in the hip06 and hip07 SoCs. There are 4 such units on the D05 board for which an appropriate DT binding has been provided. ACPI also works with an appropriate UEFI build. The hardware does not update the IV in chaining or counting modes. This is done in the drive ron completion of the cipher operation. The driver support AES, DES and 3DES block ciphers in a range of modes (others to follow). Hash and AAED support to follow. Sorry for the delay on this one, other priorities and all that... Changes since V1. 1) DT binding fixes suggested by Rob Herring in patches 1 and 3. 2) Added XTS key check as suggested by Stephan Muller. 3) A trivial use after free found during testing of the above. Changes since RFC. 1) Addition of backlog queuing as needed to support dm-crypt usecases. 2) iommu presence tests now done as Robin Murphy suggested. 3) Hardware limiation to 32MB requests worked aroud in driver so it will now support very large requests (512*32MB). Larger request handling than this would require a longer queue with the associate overheads and is considered unlikely to be necessary. 4) The specific handling related to the inline IV patch set from Stephan has been dropped for now. 5) Interrupt handler was previous more complex than necessary so has been reworked. 6) Use of the bounce buffer for small packeets is dropped for now. This is a performance optimization that made the code harder to review and can be reintroduced as necessary at a later date. 7) Restructuring of some code to simplify hash and aaed (hash implemented but not ready fo upstream at this time) 8) Various minor fixes and reworks of the code * several off by one errors in the cleanup paths * single template for enc and dec * drop dec_key as not used (enc_key was used in both cases) * drop dma pool for IVs as it breaks chaining. * lots of spinlocks changed to mutexes as not taken in atomic context. * nasty memory leak cleaned up.
