* Two definitions are required for sparsemem:
*
* MAX_PHYSMEM_BITS: The number of physical address bits required
* to address the last byte of memory.
*
* SECTION_SIZE_BITS: The number of physical address bits to cover
* the maximum amount of memory in a section.
*
* Eg, if you have 2 banks of up to 64MB at 0x80000000, 0x84000000,
* then MAX_PHYSMEM_BITS is 32, SECTION_SIZE_BITS is 26.
*
* These can be overridden in your mach/memory.h.
