MIPS: Make MIPS_CMDLINE_DTB default

2015-11-11T07:38:37+00:00

Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied
the arguments from dtb to arcs_command_line to prevent the kernel from
overwriting them.

Since there is now an option to keep the dtb arguments, default to the
new option remove the "backup" to arcs_command_line in case of USE_OF is
enabled, except for those platforms that still take the bootloader
arguments or do not use any at all.

MIPS: ralink: allow manual memory override

2014-11-24T06:45:20+00:00

RT5350 relies on the bootloader setting up the memc correctly. On some boards
the setup is incorrect leading to 32 MB being available but only 16 MB being
recognized. Allow these boards to manually override the memory range.

MIPS: Create a helper function for DT setup

2014-11-24T06:45:12+00:00

A couple of platforms register two buses and call of_platform_populate().
Move this into a common function to reduce duplication.

mips: convert fdt pointers to opaque pointers

2014-04-30T05:59:13+00:00

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.

mips: ralink: convert to use unflatten_and_copy_device_tree

2014-04-30T05:56:00+00:00

The ralink FDT code can be simplified by using
unflatten_and_copy_device_tree function. This removes all accesses to
FDT header data by the arch code.

Merge tag 'devicetree-for-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2013-11-12T07:52:17+00:00

Pull devicetree updates from Rob Herring:
"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.

- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for
deferred probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates"

MIPS: Panic messages should not end in \n.

2013-10-29T20:24:19+00:00

Panic() is going to add a \n itself and it's annoying if a panic message rolls
of the screen on a device with no scrollback.
