SysMMU v7 has a bit different registers for getting the fault info:
- there is one single register (MMU_FAULT_VA) to get the fault address
- fault access type (R/W) can be read from MMU_FAULT_TRANS_INFO
register now
- interrupt status register has different bits w.r.t. previous SysMMU
versions
- VM and non-VM layouts have different register addresses
Add correct fault handling implementation for SysMMU v7, according to
all mentioned differences. Only VID #0 (default) is handled, as VM
domains support is not implemented yet.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
