- * Traditional Malta Board Memory Map for EVA
- *
- * 0x00000000 - 0x0fffffff: 1st RAM region, 256MB
- * 0x10000000 - 0x1bffffff: GIC and CPC Control Registers
- * 0x1c000000 - 0x1fffffff: I/O And Flash
- * 0x20000000 - 0x7fffffff: 2nd RAM region, 1.5GB
- * 0x80000000 - 0xffffffff: Physical memory aliases to 0x0 (2GB)
- *
- * The kernel is still located in 0x80000000(kseg0). However,
- * the physical mask has been shifted to 0x80000000 which exploits the alias
- * on the Malta board. As a result of which, we override the __pa_symbol
- * to peform direct mapping from virtual to physical addresses. In other
- * words, the 0x80000000 virtual address maps to 0x80000000 physical address
- * which in turn aliases to 0x0. We do this in order to be able to use a flat
- * 2GB of memory (0x80000000 - 0xffffffff) so we can avoid the I/O hole in
- * 0x10000000 - 0x1fffffff.
- * The last 64KB of physical memory are reserved for correct HIGHMEM
- * macros arithmetics.
