1. PCI and reset are factored out into pq2.c. I renamed them from m82xx to pq2 because they won't work on the Integrated Host Processor line of 82xx chips (i.e. 8240, 8245, and such). 2. The PCI PIC, which is nominally board-specific, is used on multiple boards, and thus is used into pq2ads-pci-pic.c. 3. The new CPM binding is used. 4. General cleanup.

The localbus node is used to describe devices that are connected via a chip select or similar mechanism. The advantages over placing the devices under the root node are that it can be probed without probing other random things under the root, and that the description of which chip select a given device uses can be used to set up mappings if the firmware failed to do so in a useful manner. cuboot-pq2 is updated to match the binding; previously, it called itself chipselect rather than localbus, and used phandle linkage between the actual bus node and the control node (the current agreement is to simply use the fully-qualified address of the control registers, and ignore the overlap with the IMMR node).

The 8xx can only support a max of 8M during early boot (it seems a lot of 8xx boards only have 8M so the bug was never triggered), but the early allocator isn't aware of this.

The CPU15 erratum on MPC8xx chips can cause incorrect code execution under certain circumstances, where there is a conditional or indirect branch in the last word of a page, with a target in the last cache line of the next page. This patch implements one of the suggested workarounds, by forcing a TLB miss whenever execution crosses a page boundary. This is done by invalidating the pages before and after the one being loaded into the TLB in the ITLB miss handler.

These let board code set up pins and clocks without having to put magic numbers directly into the registers. The clock function is mostly duplicated from the cpm2 version; hopefully this stuff can be merged at some point.

1. Keep a global mpc8xx_immr mapping, rather than constantly creating temporary mappings. 2. Look for new fsl,cpm1 and fsl,cpm1-pic names. 3. Always reset the CPM when not using the udbg console; this is required in case the firmware initialized a device that is incompatible with one that the kernel is about to use. 4. Remove some superfluous casts and header includes. 5. Change a usage of IMAP_ADDR to get_immrbase(). 6. Use phys_addr_t, not uint, for dpram_pbase. 7. Various sparse-related fixes, such as __iomem annotations. 8. Remove mpc8xx_show_cpuinfo, which doesn't provide anything useful beyond the generic cpuinfo handler. 9. Move prototypes for 8xx support functions from board files to sysdev/commproc.h. Signed-off-by: NScott Wood <scottwood@freescale.com> Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

The existing OF glue code was crufty and broken. Rather than fix it, it has been removed, and the serial driver now talks to the device tree directly. The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).

fsl_get_immr() uses /soc/ranges to determine the immr. mpc885_get_clock() transforms a crystal frequency into a system frequency according to the PLL register settings. pq2_get_clocks() does the same as the above for the PowerQUICC II, except that it produces several different clocks. The mpc8xx/pq2 set_clocks() functions modify common properties in the device tree based on the given clock data. The mpc885/pq2 fixup_clocks() functions call get_clocks(), and pass the results to set_clocks().

Consensus was reached to put PCI nodes at the root of the tree (and not under /soc), but the phandle to a control node was rejected in favor of simply not worrying about /pci/reg overlapping /soc/ranges.

This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

As suggested by David Gibson, now that we have a separate node for the baud rate generators, it's better to use the standard clock-frequency property than a cpm-node-level fsl,brg-frequency property.

Commit 8112753b made 44x in ARCH=powerpc builds use cpu setup routines in cpu_setup_44x.S, but didn't make a similar change for ARCH=ppc, and consequently the ARCH=ppc builds fail with undefined symbols (since both use the same cputable.c). This fixes it by including cpu_setup_44x.S in the ARCH=ppc builds, and by taking out the now-redundant FPU initialization in arch/ppc/kernel/head_44x.S.
