40 * TLB0 and TLB1 Entries
42 * Out of reset, TLB1's Entry 0 maps the highest 4K for CCSRBAR.
43 * However, CCSRBAR is then relocated to CFG_CCSRBAR right after
44 * these TLB entries are established.
46 * The TLB entries for DDR are dynamically setup in spd_sdram()
47 * and use TLB1 Entries 8 through 15 as needed according to the
50 * MAS0: tlbsel, esel, nv
51 * MAS1: valid, iprot, tid, ts, tsize
52 * MAS2: epn, x0, x1, w, i, m, g, e
53 * MAS3: rpn, u0-u3, ux, sx, uw, sw, ur, sr
