;
; OEMAddressTable defines the mapping from the 4GB physical address space
; to the kernel's 512MB "un-mapped" spaces.  The kernel will create two ranges
; of virtual addresses from this table. One from 0x80000000 to 0x9FFFFFFF which
; has caching & buffering enabled and one from 0xA0000000 to 0xBFFFFFFF which
; has the cache & buffering disabled.
;
; WARNING: The above comments regarding address (0xA0000000) don't match our code.
;
;
; Each entry in the table consists of the Virtual Base Address to map to,
; the Physical Base Address to map from, and the number of megabytes to map.
;
; The order of the entries is arbitrary, but DRAM should be placed first for
; optimal performance. The table is zero-terminated, so the last entry MUST
; be all zeroes.
