s390/zcrypt: remove CEX2 and CEX3 device drivers

2023-07-24T10:12:22Z

Remove the legacy device driver code for CEX2 and CEX3 cards. The last machines which are able to handle CEX2 crypto cards are z10 EC first available 2008 and z10 BC first available 2009. The last machines able to handle a CEX3 crypto card are z196 first available 2010 and z114 first available 2011. Please note that this does not imply to drop CEX2 and CEX3 support in general. With older kernels on hardware up to the aforementioned machine models these crypto cards will get support by IBM. The removal of the CEX2 and CEX3 device drivers code opens up some simplifications, for example support for crypto cards without rng support can be removed also.

s390/zcrypt: zcrypt device driver cleanup

2018-10-09T09:21:35Z

Some cleanup in the s390 zcrypt device driver: - Removed fragments of pcixx crypto card code. This code can't be reached anymore because the hardware detection function does not recognize crypto cards < CEX2 since commit f56545430736 ("s390/zcrypt: Introduce QACT support for AP bus devices.") - Rename of some files and driver names which where still reflecting pcixx support to cex2a/cex2c. - Removed all the zcrypt version strings in the file headers. There is only one place left - the zcrypt.h header file is now the only place for zcrypt device driver version info. - Zcrypt version pump up from 2.2.0 to 2.2.1.
