crypto: ccp - Check for CCP before registering crypto algs

2014-10-05T20:41:09+00:00

commit c9f21cb6388898bfe69886d001316dae7ecc9a4b upstream.

If the ccp is built as a built-in module, then ccp-crypto (whether
built as a module or a built-in module) will be able to load and
it will register its crypto algorithms.  If the system does not have
a CCP this will result in -ENODEV being returned whenever a command
is attempted to be queued by the registered crypto algorithms.

Add an API, ccp_present(), that checks for the presence of a CCP
on the system.  The ccp-crypto module can use this to determine if it
should register it's crypto alogorithms.

crypto: ux500 - make interrupt mode plausible

2014-09-05T23:36:31+00:00

commit e1f8859ee265fc89bd21b4dca79e8e983a044892 upstream.

The interrupt handler in the ux500 crypto driver has an obviously
incorrect way to access the data buffer, which for a while has
caused this build warning:

../ux500/cryp/cryp_core.c: In function 'cryp_interrupt_handler':
../ux500/cryp/cryp_core.c:234:5: warning: passing argument 1 of '__fswab32' makes integer from pointer without a cast [enabled by default]

There are at least two, possibly three problems here:
a) when writing into the FIFO, we copy the pointer rather than the
   actual data we want to give to the hardware
b) the data pointer is an array of 8-bit values, while the FIFO
   is 32-bit wide, so both the read and write access fail to do
   a proper type conversion
c) This seems incorrect for big-endian kernels, on which we need to
   byte-swap any register access, but not normally FIFO accesses,
   at least the DMA case doesn't do it either.

This converts the bogus loop to use the same readsl/writesl pair
that we use for the two other modes (DMA and polling). This is
more efficient and consistent, and probably correct for endianess.

The bug has existed since the driver was first merged, and was
probably never detected because nobody tried to use interrupt mode.
It might make sense to backport this fix to stable kernels, depending
on how the crypto maintainers feel about that.

The checking for the type of algorithm implementation is pretty
strange here. Use regular flags to check for the type instead.
