Leif Lindholm	74bcc24992	arm64: efi: only attempt efi map setup if booting via EFI ... Booting a kernel with CONFIG_EFI enabled on a non-EFI system caused an oops with the current UEFI support code. Add the required test to prevent this.

Mark Salter	f84d02755f	arm64: add EFI runtime services ... This patch adds EFI runtime support for arm64. This runtime support allows the kernel to access various EFI runtime services provided by EFI firmware. Things like reboot, real time clock, EFI boot variables, and others. This functionality is supported for little endian kernels only. The UEFI firmware standard specifies that the firmware be little endian. A future patch is expected to add support for big endian kernels running with little endian firmware.
