Access to the SEC4 DECOs (DEscriptor COntrollers) (for debug purposes) isn't supported or used, and its register access initialization code erroneously makes illegal i/o accesses that show up as errors when run under simulation.

Some later SEC v3.x are equipped with a second IRQ line. By correctly assigning IRQ affinity, this feature can be used to increase performance on dual core parts, like the MPC8572E and P2020E. The existence of the 2nd IRQ is determined from the device node's interrupt property. If present, the driver remaps two of four channels, which in turn makes those channels trigger their interrupts on the 2nd line instead of the first. To handle single- and dual-IRQ combinations efficiently, talitos gets two new interrupt handlers and back-half workers.

Add these hmac algorithms to talitos: hmac(md5), hmac(sha1), hmac(sha224), hmac(sha256), hmac(sha384), hmac(sha512). These are all type ahash. Signed-off-by: NLee Nipper <lee.nipper@gmail.com> Fixed up to not register HMAC algorithms on sec2.0 devices. Rationale (from Lee): on an 8349E Rev1.1, there's a problem with hmac for any talitos hmac sequence requiring an intermediate hash context (Pointer DWORD 1); the result is an incorrect hmac. An intermediate hash context is required for something longer than (65536-blocksize), and for other cases when update/finup/final are used inefficiently. Interestingly, a normal hash (without hmac) works perfectly when using an intermediate context.

Apparently, NIST is tightening up its requirements for FIPS validation with respect to RNGs. Its always been required that in fips mode, the ansi cprng not be fed key and seed material that was identical, but they're now interpreting FIPS 140-2, section AS07.09 as requiring that the implementation itself must enforce the requirement. Easy fix, we just do a memcmp of key and seed in fips_cprng_reset and call it a day. v2: Per Neil's advice, ensure slen is sufficiently long before we compare key and seed to avoid looking at potentially unallocated mem.
