* MIPS: lantiq: Use of_platform_default_populate instead of __dt_register_busesMartin Blumenstingl2017-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | This allows populating syscon devices which are using "simple-mfd" instead of "simple-bus".

* MIPS: lantiq: Set physical_memsizeHauke Mehrtens2017-02-151-0/+6
| | | | | | | | | | | | | | | | | physical_memsize is needed by the vpe loader code and the platform specific code has to define it. This value will be given to the firmware loaded with the VPE loader. I am not aware of any standard interface or better value to provide here.

* MIPS: store the appended dtb address in a variableJonas Gorski2016-08-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Instead of rewriting the arguments to match the UHI spec, store the address of a appended or UHI supplied dtb in fw_supplied_dtb. That way the original bootloader arugments are kept intact while still making the use of an appended dtb invisible for mach code. Mach code can still find out if it is an appended dtb by comparing fw_arg1 with fw_supplied_dtb.

* MIPS: Lantiq: Add support for device tree file from boot loaderHauke Mehrtens2016-05-131-2/+11
| | | | | | | | | | | | | This fetches the device tree file like it is specified in the MIPS UHI interface if one was found. This is also used when the device tree file was appended to the kernel image with cat. This code is copied from arch/mips/bmips/setup.c.

* MIPS: Make MIPS_CMDLINE_DTB defaultJonas Gorski2015-11-111-2/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | 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: convert fdt pointers to opaque pointersRob Herring2014-04-301-1/+1
| | | | | | | | | | 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: lantiq: copy built-in DTB out of init sectionRob Herring2014-04-301-12/+1Star
| | | | | | | | | | | | The existing code is buggy because built-in DTBs are in init memory. Fix this by using the unflatten_and_copy_device_tree function.
