[ Upstream commit 6cb345939b8cc4be79909875276aa9dc87d16757 ]

PCI device 0x1134 shares same register features as PCI device 0x17E0.
Hence reuse same data for the new PCI device ID 0x1134.

commit 8006aff15516a170640239c5a8e6696c0ba18d8e upstream.

According to the review by Bill Cox [1], the Atmel SHA204A random number
generator produces random numbers with very low entropy.

Set the lowest possible entropy for this chip just to be safe.

<title>crypto: ccp - Fix check for the primary ASP device</title>

<content type='text'>
commit 07bb097b92b987db518e72525b515d77904e966e upstream.

Currently, the ASP primary device check does not have support for PCI
domains, and, as a result, when the system is configured with PCI domains
(PCI segments) the wrong device can be selected as primary. This results
in commands submitted to the device timing out and failing. The device
check also relies on specific device and function assignments that may
not hold in the future.

Fix the primary ASP device check to include support for PCI domains and
to perform proper checking of the Bus/Device/Function positions.

can be 0 bytes, and the hardware can handle this
scenario. Therefore, remove the incorrect validation
for this case.

The compiler correctly warns that hv_nxc may be used uninitialised
as that will occur when NX-GZIP is unavailable.

Fix it by rearranging the code and delay setting caps_feat until
the final query succeeds.

commit e80cf84b608725303113d6fe98bb727bf7b7a40d upstream.

If we encounter an error when registering alorithms with the crypto
framework, we just bail out and don't unregister the ones we
successfully registered in prior iterations of the loop.

Add code that goes back over the algos and unregisters them before
returning an error from qce_register_algs().
