Hi Phillipe,

I needed to test some Xen things on a model I could debug so I took
the liberty of re-basing you patches from a 2 years ago. Most of the
changes involve dropping patches since merged and dealing with the
resultant merging fallout. The fix I posted on Friday for the
calculation of the ram base for kernel loading is included. Other
tweaks involve moving the location of peri_base to what is indicated
by the DTBs (I'm still not sure where the Linux addresses come from,
does it re-map the physical address space somewhere?).

My testing ended at getting Xen to boot up and at least echo some
stuff to the console:

  ./qemu-system-aarch64 -machine raspi4b -serial mon:stdio -kernel ~/lsrc/xen/xen-only.cross.arm64/xen/xen -append "dom0_mem=1G,max:1G loglvl=all guest_loglvl=all console=d
  tuart dtuart=serial0 sync_console" -display none -dtb ./bcm2711-rpi-4-b.dtb            
  - UART enabled -

  - Turning on paging -               
  - Zero BSS -

  (XEN) Bad console= option 'dtuart'

My next steps involve debugging Xen so I thought I'd post where I am
for the next person that wants to properly wire up the Pi4.
