+ * ROGUE Device Virtual Address Space Definitions
+ *
+ * This file defines the ROGUE virtual address heaps that are used in
+ * application memory contexts. It also shows where the Firmware memory heap
+ * fits into this, but the firmware heap is only ever created in the
+ * kernel driver and never exposed to userspace.
+ *
+ * ROGUE_PDSCODEDATA_HEAP_BASE and ROGUE_USCCODE_HEAP_BASE will be programmed,
+ * on a global basis, into ROGUE_CR_PDS_EXEC_BASE and ROGUE_CR_USC_CODE_BASE_*
+ * respectively. Therefore if client drivers use multiple configs they must
+ * still be consistent with their definitions for these heaps.
+ *
+ * Base addresses have to be a multiple of 4MiB.
+ * Heaps must not start at 0x0000000000, as this is reserved for internal
+ * use within the driver.
+ * Range comments, those starting in column 0 below are a section heading of
+ * sorts and are above the heaps in that range. Often this is the reserved
+ * size of the heap within the range.
