The Linux CPU number doesn't necessarily match up with the ID used for a VP by hardware. Convert the CPU number to the HW ID using mips_cm_vp_id when writing to the VP(E)_OTHER_ADDR register in order to ensure that we correctly access registers for the VPs of secondary cores. This most notably affects systems using CM3, such as those based around I6400. Signed-off-by:

Fix mips_cm_max_vp_width for UP kernels where it previously referenced smp_num_siblings, which is not declared for UP kernels. This led to build errors such as the following: drivers/built-in.o: In function `$L446': irq-mips-gic.c:(.text+0x1994): undefined reference to `smp_num_siblings' drivers/built-in.o:irq-mips-gic.c:(.text+0x199c): more undefined references to `smp_num_siblings' follow On UP kernels simply return 1, leaving the reference to smp_num_siblings in place only for SMP kernels.

This is similar to commit 934c7923 ("MIPS: asm: r4kcache: Add MIPS R6 cache unroll functions"). The CACHE instruction has been redefined for MIPSr6 and it reduced its offset field to 8 bits. This leads to micro-assembler field overflow warnings when booting SMP MIPSr6 cores like the following one: Call Trace: [<ffffffff8010af88>] show_stack+0x68/0x88 [<ffffffff8056ddf0>] dump_stack+0x68/0x88 [<ffffffff801305bc>] warn_slowpath_common+0x8c/0xc8 [<ffffffff80130630>] warn_slowpath_fmt+0x38/0x48 [<ffffffff80125814>] build_insn+0x514/0x5c0 [<ffffffff806ee134>] cps_gen_cache_routine.isra.3+0xe0/0x1b8 [<ffffffff806ee570>] cps_pm_init+0x364/0x9ec [<ffffffff80100538>] do_one_initcall+0x90/0x1a8 [<ffffffff806e8c14>] kernel_init_freeable+0x160/0x21c [<ffffffff8056b6a0>] kernel_init+0x10/0xf8 [<ffffffff801059f8>] ret_from_kernel_thread+0x14/0x1c We fix this by incrementing the base register on every loop.

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.

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. Signed-off-by:

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].

Broadcom ARM home routers store SPROM content in NVRAM just like MIPS 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 should fit there as well. 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). Signed-off-by:
