The architecture code does not need to access the internals of the FDT
blob directly, so make the pointers to it void * and use char arrays
for section variables.

The existing code is buggy because built-in DTBs are in init memory.
Fix this by using the unflatten_and_copy_device_tree function.

This removes all accesses to FDT header data by the arch code.

'compatible' is used by strlen() in __of_device_is_compatible().

Ensure strings are always '\0' terminated.

'of_ids is not a structure in "include/uapi/*", so no need to initialize
it completly; using strlcpy() instead of strncpy() will do.

The bootmem was incorrectly freed resulting in lots of dangling pointers.
Additionally we should use of_platform_populate() as the Documentaion tells us
to do so.

Add initial support for Mips based SoCs made by Lantiq. This series will add
support for the XWAY family.

The series allows booting a minimal system using a initramfs or NOR. Missing
drivers and support for Amazon and GPON family will be provided in a later
series.
