+ * arch_mem_init - initialize memory managment subsystem

+ *  o plat_mem_setup() detects the memory configuration and will record detected
+ *    memory areas using add_memory_region.
+ *  o parse_cmdline_early() parses the command line for mem= options which,
+ *    iff detected, will override the results of the automatic detection.
+ *
+ * At this stage the memory configuration of the system is known to the
+ * kernel but generic memory managment system is still entirely uninitialized.

+ *  o bootmem_init()
+ *  o sparse_init()
+ *  o paging_init()
+ *
+ * At this stage the bootmem allocator is ready to use.
+ *
+ * NOTE: historically plat_mem_setup did the entire platform initialization.
+ *       This was rather impractical because it meant plat_mem_setup had to
+ * get away without any kind of memory allocator.  To keep old code from
+ * breaking plat_setup was just renamed to plat_setup and a second platform
+ * initialization hook for anything else was introduced.
