38 * The early kernel mapping on ARM currently only maps from the base of DRAM
39 * to the end of the kernel image. The kernel is loaded at DRAM base + 0x8000.
40 * The early kernel pagetable uses DRAM base + 0x4000 to DRAM base + 0x8000,
41 * so that leaves DRAM base to DRAM base + 0x4000 available.
