Summary: Boot arm64 kernel using booti command from U-boot. booti can relocate initrd image into higher ram addresses, therefore align the initrd load address to 1GiB and create VA = PA map for it. Create L2 pagetable entries to copy the initrd image into KVA. (parts of the code in https://reviews.freebsd.org/D13861 was referred and used as appropriate) Submitted by: Siddharth Tuli <siddharthtuli_gmail.com> Reviewed by: manu Sponsored by: Juniper Networks, Inc Differential Revision: https://reviews.freebsd.org/D22255
