* Initialization functions called by the common initarm() function in
* arm/machdep.c (but not necessarily from the custom initarm() functions of
* older code).
*
* - initarm_early_init() is called very early, after parsing the boot params
* and after physical memory has been located and sized.
*
* - initarm_devmap_init() is called as one of the last steps of early virtual
* memory initialization, shortly before the new page tables are installed.
*
* - initarm_lastaddr() is called after initarm_devmap_init(), and must return
* the address of the first byte of unusable KVA space. This allows a
* platform to carve out of the top of the KVA space whatever reserves it
* needs for things like static device mapping, and this is called to get the
* value before calling pmap_bootstrap() which uses the value to size the
* available KVA.
*
* - initarm_gpio_init() is called after the static device mappings are
* established and just before cninit(). The intention is that the routine
* can do any hardware setup (such as gpio or pinmux) necessary to make the
* console functional.
*
* - initarm_late_init() is called just after cninit(). This is the first of
* the init routines that can use printf() and expect the output to appear on
* a standard console.
