Incidentally, with Jarkko's tree the tpm_tis module refuses to
initialize (with or without force=1):

tpm_tis 00:03: can't request region for resource [mem 0xfed40000-0xfed44fff]
tpm_tis: probe of 00:03 failed with error -16

The memory region is not marked reserved by the BIOS:

e820: BIOS-provided physical RAM map:
Xen: [mem 0x0000000000000000-0x000000000005ffff] usable

Xen: [mem 0x0000000100000000-0x0000000505deafff] usable

With force=1, /proc/iomem shows:

fed30000-fedfffff : RAM buffer
  fed40000-fed44fff : tpm_tis

I can work around this problem by passing memmap=0x5000$0xfed40000 on
the kernel command line.
