Introduce a "generic" platform, which aims to be board-agnostic by making use of device trees passed by the boot protocol defined in the MIPS UHI (Universal Hosting Interface) specification. Provision is made for supporting boards which use a legacy boot protocol that can't be changed, but adding support for such boards or any others is left to followon patches. Right now the built kernels expect to be loaded to 0x80100000, ie. in kseg0. This is fine for the vast majority of MIPS platforms, but nevertheless it would be good to remove this limitation in the future by mapping the kernel via the TLB such that it can be loaded anywhere & map itself appropriately. Configuration is handled by dynamically generating configs using scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc makes use of it. This allows for variations upon the configuration, eg. differing architecture revisions or subsets of driver support for differing boards, to be handled without having a large number of defconfig files.

Add support for generating kernel images in the Flattened Image Tree (.itb) format as supported by U-Boot. This format is essentially a Flattened Device Tree binary containing images (kernels, DTBs, ramdisks) and configurations which link those images together. The big advantages of FIT images over the uImage format are: - We can include FDTs in the kernel image in a way that the bootloader can extract it & manipulate it before providing it to the kernel. Thus we can ship FDTs as part of the kernel giving us the advantages of being able to develop & maintain the DT within the kernel tree, but also have the benefits of the bootloader being able to manipulate the FDT. Example uses for this would be to inject the kernel command line into the chosen node, or to fill in the correct memory size. - We can include multiple configurations in a single kernel image. This means that a single FIT image can, given appropriate bootloaders, be booted on different boards with the bootloader selecting an appropriate configuration & providing the correct FDT to the kernel. - We can support a multitude of hashes over the data.

On MIPS64 we define the default CAC_BASE as one of the xkphys regions of the virtual address space. Since the CCA is encoded in bits 61:59 of xkphys addresses, fixing CAC_BASE to any particular one prevents us from dynamically changing the CCA as we do for MIPS32 where CAC_BASE is placed within kseg0. In order to make the kernel more generic, drop the current kludge that gives CAC_BASE CCA=3 if CONFIG_DMA_NONCOHERENT is selected (disregarding CONFIG_DMA_MAYBE_COHERENT) & CCA=5 (which is not standardised by the architecture) otherwise. Instead read Config.K0 and generate the appropriate offset into xkphys, presuming that either the bootloader or early kernel code will have configured Config.K0 appropriately. This seems like the best option for a generic implementation. The ip27 spaces.h is adjusted to set its former value of CAC_BASE, since it's the only user of CAC_BASE from assembly (in its smp_slave_setup macro). This allows the generic case to focus solely on C code without breaking ip27.

If a bus error occurs on a system with a MIPS Coherence Manager (CM) then the CM may hold useful diagnostic information. Printing this out has so far been left up to boards, with the requirement that they register a board_be_handler function & call mips_cm_error_decode() from there. In order to avoid boards other than Malta needing to duplicate this code, call mips_cm_error_decode() automatically if the board registers no board_be_handler, and remove the Malta implementation of that. This patch results in no functional change, but removes a further piece of platform-specific code.

On some MIPS systems, a subset of devices may have DMA coherent with CPU caches. For example in systems including a MIPS I/O Coherence Unit (IOCU), some devices may be connected to that IOCU whilst others are not. Prior to this patch, we have a plat_device_is_coherent() function but no implementation which does anything besides return a global true or false, optionally chosen at runtime. For devices such as those described above this is insufficient. Fix this by tracking DMA coherence on a per-device basis with a dma_coherent field in struct dev_archdata. Setting this from arch_setup_dma_ops() takes care of devices which set the dma-coherent property via device tree, and any PCI devices beneath a bridge described in DT, automatically.

There are no cases where plat_device_is_coherent() will return zero whilst hw_coherentio is non-zero, and acting any differently in such a case doesn't make much sense - if a device is non-coherent with the CPU caches then access to memory "coherent" with DMA must be uncached.

The coherentio variable has previously been used as a boolean value, indicating whether the user specified that coherent I/O should be enabled or disabled. It failed to take into account the case where the user does not specify any preference, in which case it makes sense that we should default to coherent I/O if the hardware supports it (hw_coherentio is non-zero). Introduce an enum to clarify the 3 different values of coherentio & use it throughout the code, modifying plat_device_is_coherent() & r4k_cache_init() to take into account the default case.

The Kconfig entries are created such that platforms have to select CONFIG_PCI_DRIVERS_GENERIC if they wish to use it - that is, the default is CONFIG_PCI_DRIVERS_LEGACY so that existing platforms need no modification. The functions declared in pci.h are rearranged with those provided only by pci-legacy.c being guarded by an #ifdef CONFIG_PCI_DRIVERS_LEGACY to ensure they are only used in configurations where they are implemented.

Current instruction decoder for uprobe/kprobe handler only handles branches with delay slots. For compact branches the behaviour is rather unpredictable - and depending on the encoding of a compact branch instruction may result in one (or more) of: - executing an instruction that follows a branch which wasn't in a delay slot and shouldn't have been executed - incorrectly emulating a branch leading to a jump to a wrong location - unexpected branching out of the single-stepped code and never reaching the breakpoint that should terminate the probe handler Results of these actions are generally unpredictable, but can end up with a probed application or kernel crash, so disable placing probes on compact branches until they are handled properly.

Malta boards can have more than 256MB DDR available, but we have previously only made use of up to 256MB (ie. the DDR accessible via kseg0) by default, without the user manually specifying mem= kernel parameters. This patch causes all available DDR, as reported by the bootloader via the ememsize or memsize environment variables or optionally on the command line, to be used when possible without the user needing to manually provide the memory ranges. Malta now has 2 subtly different memory maps which have to be taken into account when setting this up. The original memory map (referred to by the code as v1) has up to 2GB of DDR aliased in both the upper & lower halves of the 32 bit physical address space, with a 256MB I/O region obscuring 0x10000000-0x1fffffff only in the lower alias. The revised v2 memory map is flat with up to 4GB DDR starting from 0x0, and the I/O region obscures 256MB of DDR which becomes inacessible. The memory map in use is indicated by a register provided by the rocit2 system controller, which is checked in order to set up the kernels memory ranges accordingly.
