Added Files:
src/sys/arch/aarch64/aarch64: pmapboot.c
Log Message:
cleanup locore, and changed the way to map memories during boot.
- add functions bootpage_enter() and bootpage_alloc() to adapt various layout
of physical memory map. especially for 64bit physical memory layout.
pmapboot_alloc() allocates pagetable pages from _end[].
- changed to map only the required amount for PA=VA identity mapping
(kernel image, UART device, and FDT blob) with L2_BLOCK(2Mbyte).
- changing page permission for kernel image, and making KSEG mapping are done
at cpu_kernel_vm_init() instead of at locore.
- optimize PTE entries with PTE Contiguous bit. it is enabled on devmap only
for now.
