* 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.
