powerpc/powernv: Create OPAL sglist helper functions and fix endian issues 2014-04-28T03:11:23+00:00 Anton Blanchard anton@samba.org 2014-04-22T05:01:26+00:00 3441f04b4b62758a798f9fbbf2047dfedf0329a5 We have two copies of code that creates an OPAL sg list. Consolidate these into a common set of helpers and fix the endian issues. The flash interface embedded a version number in the num_entries field, whereas the dump interface did did not. Since versioning wasn't added to the flash interface and it is impossible to add this in a backwards compatible way, just remove it.
