arm/versatile: Add device tree support For testing the dt work, define a dt-enabled versatile platform. This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.

ARM: versatile: merge mach code into a single file With DT-only support now in place and most of the legacy code removed, the separation of core.c and versatile_dt.c makes little sense. The headers in mach include directory also have to move for multi-platform support, but with a single .c file the remaining definitions needed can also be moved into the versatile_dt.c. In the move, the system registers and IB2 registers are converted to run-time mappings and all register accesses converted to use readl/writel.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

ARM: make arrays containing machine compatible strings const The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.
