Use local variables for ref, cpu, ddr and ahb rates in SoC specific clock init functions. The patch has no functional changes, it is an interim change in preparation of the next patch.

Instead of accessing the rate field of the static clock devices directly, use the recently introduced helper function to get the rate of the basic clocks. The static ath79_{ahb,cpu,ddr,ref}_clk variables will be removed by a subsequent patch. The actual change is in preparation of that. Also move the clock frequency printing code into the plat_time_init function. We are getting the cpu clock rate there already so we can save an extra call of the helper.

The watchdog device on the AR933x is connected to the AHB clock, however the current code uses the reference clock. Due to the wrong rate, the watchdog driver can't calculate correct register values for a given timeout value and the watchdog unexpectedly restarts the system. The code uses the wrong value since the initial commit 04225e1d (MIPS: ath79: add AR933X specific clock init) The patch fixes the code to use the correct clock rate to avoid the problem.

The ath79 code supports various SoCs which are using either a 24Kc or a 74Kc core. The 74Kc core has DSP support, so don't hardwire the values to zero. Commit 00dc5ce2 (MIPS: ath79: don't hardcode the unavailability of the DSP ASE) has fixed this already, but that change got reverted by 47503256 (MIPS: Hardwire detection of DSP ASE Rev 2 for systems, as required.)

Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot image of vmlinux.bin.gz), and then symlinks it to uImage. This allows for the use of other compression algorithms in future, and is how a few other architectures do it. It's enabled conditionally on load-y >= 0xffffffff80000000 which hopefully allows 64bit kernels to also work as long as the load and entry address can be represented by the 32bit addresses in the U-Boot image format.

The vmlinux load address and entry address is calculated in multiple places: - arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or defined by the platform) and passes it to arch/mips/boot/compressed/Makefile. - arch/mips/boot/compressed/Makefile calculates kernel entry using nm. - arch/mips/lasat/image/Makefile calculates both load and entry address using nm. Lets combine these in the main Makefile and then pass them as Make parameters to each of the three boot image Makefiles (in boot/, boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use them, but will soon need to for U-Boot image targets. The existing load-y definition is used in preference to calculating the load address using nm.

Add symlink to include/dt-bindings from arch/mips/boot/dts/include/ to match the ones in ARM and Meta architectures so that preprocessed device tree files can include various useful constant definitions. See commit c58299aa (kbuild: create an "include chroot" for DT bindings) merged in v3.10-rc1 for details. MIPS structures it's dts files a little differently to other architectures, having a separate dts directory for each SoC/platform, but most of the definitions in the dt-bindings/ directory are common so for now lets just have a single "include chroot" for all MIPS platforms.

A lot of 64-bit systems supported by Linux/MIPS have boot firmware or bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32 target exists to support these systems. Therefore, it'd be nice if the tar-pkg target recognised this, and included the right version when packaging up a binary of the kernel. This updates buildtar to support MIPS targets. MIPS may use 'vmlinux' or 'vmlinux.32' depending on the target system. This uses 'vmlinux.32' in preference to 'vmlinux' where present (although I should check which is newer), including either file as /boot/vmlinux-${version}.

Fix I/O space setup, so that on non-PCI systems using inb()/outb() won't crash the system. Some drivers may try to probe I/O space and for that purpose we can just allocate some normal memory initially. Drivers trying to reserve a region will fail early as we set the size to 0. If a real I/O space is present, the PCI/PCIe support code will re-adjust the values accordingly. Tested with EdgeRouter Lite by enabling CONFIG_SERIO_I8042 that caused the originally reported crash.
