- * Because of the wide memory address space between physical RAM
- * banks, it's convenient to use Linux's NUMA support to represent our
- * memory map. Assuming all memory nodes have equal access
- * characteristics, we then have a generic discontiguous memory setup.
- *
- * Of course, all this isn't mandatory for implementations with only
- * one used memory bank. For those, simply undefine
- * CONFIG_DISCONTIGMEM. However, keep in mind that a featurefull
- * system will need more than 4MiB of RAM.
- *
- * The contiguous memory blocks are small enough that it pays to
- * aggregate two banks into one node. Setting BANKS_PER_NODE to 2
- * puts pairs of banks into a node.
- *
- * A typical layout would start like this:
- *
- * node 0: 0xc0000000
- * 0xc1000000
- * node 1: 0xc4000000
- * 0xc5000000
- * node 2: 0xc8000000
- * 0xc9000000
- *
- * The proximity of the pairs of blocks makes it feasible to combine them.
