This tool does one thing only: it modifies the kernel parameters
used in a .axf file that is turn used by the ARM FAST or Foundation
models to run an ARMv8 platform simulation.

The .axf file in this directory is as it says, useless.  It will not
boot.  It is only used as a template to create an axf file (sans
initrd) that _will_ boot.

The ./paxf program takes two parameters: the first is the name to use
for the output axf file; the second is the string to use for the kernel
parameters in the axf file.  It also assumes that linux-system-useless.axf
is in ./.

To build it:

        $ make

To run it:

        $ ./paxf <output-file> <kernel-parameters>

For example, to recreate the axf file I use for an NFS root:
      
        $ ./paxf foo.axf "root=/dev/nfs nfsroot=172.17.100.1:/home/ahs3/armv8-model/nfs-root,tcp,v3 rw ip=172.17.100.2:172.17.100.1:172.17.100.1:255.255.255.0:aarch64:eth0:none console=ttyAMA0 mem=2G earlyprintk debug maxcpus=2"
