MIPS: traps: Make sure secondary cores have a sane ebase register
...
We shouldn't trust that the secondary cores will have a sane ebase register
(either from the bootloader or during the hardware design phase) so use the
ebase address as calculated by the boot CPU.

MIPS: Detect MIPSr6 Virtual Processor support
...
MIPSr6 introduces support for "Virtual Processors", which are
conceptually similar to VPEs from the now-deprecated MT ASE. Detect
whether the system supports VPs using the VP bit in Config5, adding
cpu_has_vp for use by later patches.

MIPS: ath79: update devicetree clock support for AR9132
...
Current ath79 clock.c code does not read reference clock and
pll setup from devicetree. E.g. you can set any clock rate value
in board DTS but it will have no effect on the real clk calculation.
This patch fixes some AR9132 devicetree clock support defects:
* clk initialization function ath79_clocks_init_dt_ng()
is introduced; it actually gets pll block base register
address and reference clock from devicetree;
* pll register parsing code is moved to the separate
ar724x_clk_init() function; this function
can be called from platform code or from devicetree code.
Also mips_hpt_frequency value is set from dt, so the appropriate
clock parameter is added to the cpu@0 devicetree node.
The same approach can be used for adding AR9331 devicetree support.

MIPS: dts: qca: ar9132: use short references for dt nodes
...
Here are some Sascha Hauer's arguments for using aliases in the dts
files:
- using aliases reduces the number of indentations in dts files;
- dts files become independent of the layout of the dtsi files
(it becomes possible to introduce another bus {} hierarchy between
a toplevel bus and the devices when you have to);
- less chances for typos. if &i2c2 does not exist you get an error.
If instead you duplicate the whole path in the dts file a typo
in the path will just create another node.

The TP-LINK TL-WR1043ND board has only one serial port,
so replacing the default of 0 with 0 does nothing useful.
Moreover, the correct name for aliases node is "aliases" not "alias".
An overview of the "aliases" node usage can be found
on the device tree usage page at devicetree.org [1].
Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

ones. To share SPROM code we need to move it out of arch/mips/ to some
common place. We already have bcm47xx_nvram in firmware path and SPROM

This driver is responsible for parsing SoC configuration data into a
struct shared between ssb and bcma buses.
This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0
(ARCH_BCM_5301X).
