Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  Support for PowerPC Nest (NX) encryption acceleration. This
	  module supports acceleration for AES and SHA2 algorithms on
	  the pSeries platform.  If you choose 'M' here, this module
	  will be called nx_crypto.

	  Support for PowerPC Nest (NX) compression acceleration. This
	  module supports acceleration for compressing memory with the 842
	  algorithm using the cryptographic API.  One of the platform
	  drivers must be selected also.  If you choose 'M' here, this
	  module will be called nx_compress.
