This patch series enable an accelerated AES/GCM stitched implementation for
Power10+ CPU(ppc64le).  This module supports AEAD algorithm.  The stitched
implementation provides 3.5X+ better performance than the baseline.

This patch has been tested with the kernel crypto module tcrypt.ko and has
passed the selftest.

Danny Tsen (7):
  powerpc/crypto: Define new module in Kconfig.
  powerpc/crypto: Create new module driver.
  powerpc/crypto: Functions to set round keys and encrypt data.
  powerpc/crypto: Functions for creating hash table and generate hash.
  powerpc/crypto: Glue code to create AEAD algorithm module.
  powerpc/crypto: Added new stitched AES/GCM implementation.
  powerpc/crypto: Perl script to process PowerPC asember source.

Please make sure you've tested it with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.

Hi Eric,

I will test with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y and provide 
updates.  Please ignore my resend patch that I just sent so it is 
threaded under patch 0.

Thanks.

-Danny
