crypto: Add CRYPTO_ALG_KERN_DRIVER_ONLY flag

2012-01-13T05:38:40+00:00

The added CRYPTO_ALG_KERN_DRIVER_ONLY indicates whether a cipher
is only available via a kernel driver. If the cipher implementation
might be available by using an instruction set or by porting the
kernel code, then it must not be set.

crypto: picoxcell - fix boolean and / or confusion

2011-12-20T07:20:05+00:00

The AES engine only supports 128 and 256 bit keys so we should correctly
test for that.

crypto: convert drivers/crypto/* to use module_platform_driver()

2011-11-30T08:12:48+00:00

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

crypto: picoxcell - fix possible invalid pointer dereference

2011-08-10T11:00:27+00:00

The completion callback will free the request so we must remove it from
the completion list before calling the callback.

crypto: picoxcell - add connection ID to the clock name

2011-08-10T11:00:24+00:00

For using the device tree probing we use a connection ID for the
clk_get() operation.

crypto: picoxcell - convert to platform ID table

2011-08-10T11:00:24+00:00

Use a platform ID table and a single platform_driver.  It's neater and
makes the device tree addition easier and more consistent.  Rename the
match values to be inline with what they'll be in the device tree
bindings.  There aren't any current in-tree users of the existing device
names.

crypto: picoxcell - fix possible status FIFO overflow

2011-03-27T02:48:29+00:00

The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status
FIFO.  The command FIFO takes the requests that are to be performed and
the status FIFO reports the results.  It is possible to get into the
situation where there are more free spaces in the command FIFO than the
status FIFO if we don't empty the status FIFO quickly enough resulting
in a possible overflow of the status FIFO.  This can result in incorrect
status being reported in the status FIFO.

Make sure that when we are submitting requests the number of requests
that have been dispatched but not yet popped from the status FIFO does
not exceed the size of a single FIFO.

crypto: picoxcell - add support for the picoxcell crypto engines

2011-02-21T11:42:40+00:00

Picochip picoXcell devices have two crypto engines, one targeted
at IPSEC offload and the other at WCDMA layer 2 ciphering.
