+ *
+ * The GSP only understands 4K pages (GSP_PAGE_SIZE), so even if the kernel is

+ * the GSP an array of 4K pages. Fortunately, since the buffer is

+ *
+ * The buffers must be a multiple of GSP_PAGE_SIZE. GSP-RM also currently

+ * Level 1, since it's also only one page in size, contains up to 512 entries,

+ *
+ * Level 2 can be up to 512 pages in size, and each of those entries points to
+ * the next page of the firmware image. Since there can be up to 512*512

+ *
+ * Internally, the GSP has its window into system memory, but the base

+ * physical addresses. All this should happen transparently.
