Cache translations for pages rather than by exact address. This shows
a large improvement in efficiency for some specific cases:

Latest kernel introduces KIMAGE_VADDR which allows the
virtual base of the kernel region to be below PAGE_OFFSET.

For calculating the non-LPAE ARMv7 TTBR0 offset, use swapper_pg_dir_addr
obtained from an address lookup instead of hardcoded value.

To generate proper simulator launching scripts, the TTBR needs
to be set in the MMU object. This was missing for LPAE page tables.
Set it.

We don't support python3 at all and python2.6 can only be used if the
user installs an extra package (OrderedDict [1]). Ask for python2
explicitly in the shebang line to resolve the python3 issues and print
some instructions to the user regarding python2.6 when that is used.

If the user insists on using python2.6, provide a command line
switch (--force-26) to skip the version check. To reduce clutter, don't
document this switch in the --help text but inform the user about its
existence when we error out due to the python2.6 check.

In order to even print an error message in python3 we have to first
ensure that our code is valid in python3, otherwise the interpreter
fails to even start executing our code (so we can't print any
messages). Use 2to3 to patch up some print statements, etc. Also fix
inconsistent whitespace, which is a syntax error on python3.

The IOMMU parser currently only supports short-descriptor format page
tables but hardware supports long-descriptor format page tables. Add
support for the long-descriptor format. Most of the existing LPAE MMU
code can be re-used for this, although it must be refactored a bit.

The LPAE MMU code can be re-used for other modules that need page table
parsing (like the LPAE IOMMU page tables). Refactor the code a bit so
that it can be easily re-used later.

do_fl_sl_level_lookup is a class method, so it needs to be called on a
class object. Add some missing `self' class objects.

MMU.virt_to_phys currently lacks a docstring. They're useful, so add
one.

Ram dumps are now being generated for 64-bit ramdumps. Update the
parser to account for this.

When adding a new board, it can be non-obvious what went wrong if the
board is not immediately detected. Add an option to trace through
socinfo addresses for a specific board to print out useful addresses
as a debugging aid. Also clean up some error handling, mostly among
the tracing code.

After a crash, ramdumps may be collected for analysis. The ram
parser is a tool to aid in analysis of these dumps. The script
extracts useful information from the dumps to help with debugging.
Please see the README for full details.
