Add default configuration for the AArch64 Foundation V8 simulator 



Note that this configuration doesn't build entirely: the user must
manually run "make busybox-menuconfig" and disable the "Mount NFS
filesystems" option, because the toolchain does not have RPC support.

This issue will be fixed once the support for toolchain without RPC
will be integrated.

This is the support for the ARM Foundation v8 machine emulated by the

ARM software simulator of the AArch64 architecture.



First, one has to download the AArch64 software simulator from:



  https://silver.arm.com/download/download.tm?pv=1317469



Then, use the arm_foundationv8_defconfig configuration to build your

Buildroot system.



Note that the Busybox build will fail due to the lack of rpc/rpc.h

(the AArch64 toolchain does not have RPC support). Run 'make

busybox-menuconfig', and in 'Linux System Utilities', disable the

option 'Support mounting NFS file systems on Linux < 2.6.23' and

restart the build. This problem will be fix in upcomins versions of

Buildroot.



Finally, boot your system with:



 ${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/Foundation_v8 \

    --image output/images/linux-system.axf \

    --block-device output/images/rootfs.ext2 \

    --network=nat



You can get network access from within the simulated environment

by requesting an IP address using DHCP (run the command 'udhcpc').
