From 02f6ebe3f176c8abb1f7ff35ca55012fdedb387d Mon Sep 17 00:00:00 2001 From: Dan Crowell Date: Wed, 22 Aug 2018 17:37:38 -0500 Subject: New FAPI2 interfaces to read and write MMIO ranges Adding 2 new fapi2 interfaces for platforms to implement: - getMMIO - putMMIO These functions will read/write a data buffer into a known memory-mapped i/o space based on an address that is relative to the input target.
