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. Remove it until proper support (via DECORR) is added. Signed-off-by:

This patch converts the drivers in drivers/crypto/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

Job descriptors only contain header and seq pointers. Other commands are stored in separate shared descriptors for encrypt, decrypt and givencrypt, stored as arrays in caam_ctx. This requires additional macros to create math commands to calculate assoclen and cryptlen. Signed-off-by:

In doing so, sha512 sized keys would not fit with the current descriptor inlining mechanism, so we now calculate whether keys should be referenced instead by pointers in the shared descriptor. also, use symbols for descriptor text lengths, and, ahem, unmap and free key i/o memory in cra_exit.

Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.

during recent descriptor development, an Invalid Sequence Command error triggered a: BUG: recent printk recursion! due to insufficient memory allocated for the error text. The Invalid Sequence Command error text is the longest. The length of the maximum error string is computed as the sum of: "DECO: ": 6 "jump tgt desc idx 255: ": 23 Invalid Sequence Command text: 272 zero termination character: 1 i.e, 302 characters. Define this maximum error string length in error.h and fix caam_jr_strstatus callsites. Signed-off-by:

- add IRQF_SHARED to request_irq flags to support parts such as the p1023 that has one IRQ line per couple of rings. - resetting a job ring triggers an interrupt, so move request_irq prior to jr_reset to avoid 'got IRQ but nobody cared' messages. - disable IRQs in h/w to avoid contention between reset and interrupt status - delete invalid comment - if there were incomplete jobs, module would be in use, preventing an unload.

The SEC4 supercedes the SEC2.x/3.x as Freescale's Integrated Security Engine. Its programming model is incompatible with all prior versions of the SEC (talitos). The SEC4 is also known as the Cryptographic Accelerator and Assurance Module (CAAM); this driver is named caam. This initial submission does not include support for Data Path mode operation - AEAD descriptors are submitted via the job ring interface, while the Queue Interface (QI) is enabled for use by others. Only AEAD algorithms are implemented at this time, for use with IPsec. Many thanks to the Freescale STC team for their contributions to this driver. Signed-off-by:
