The CONFIG_FSL_BOOKE mmu setup code fails when CONFIG_HIGHMEM=y and the 3 fixed TLB entries cannot exactly map the lowmem size. Each TLB entry can map 4MB, 16MB, 64MB or 256MB, so the failure is observed when the kernel lowmem size is not equal to the sum of up to 3 of those values. Normally, memory is sized in nice numbers, but I observed this problem while testing a crash dump kernel. The failure can also be observed by artificially reducing the kernel's main memory via the mem= kernel command line parameter. This commit fixes the problem by setting __initial_memory_limit in adjust_total_lowmem(). Signed-off-by:

This patch makes numerous miscellaneous code improvements to the QE library. 1. Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type() (every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all callers of ucc_set_type() accordingly. 2. Remove the unused enum ucc_pram_initial_offset. 3. Refactor qe_setbrg(), also implement work-around for errata QE_General4. 4. Several printk() calls were missing the terminating \n. 5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where appropriate. 6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed with the wrong value. 7. Add the protocol type to struct us_info and updated ucc_slow_init() to use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED. 8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx() 9. Add several macros in qe.h (mostly for slow UCC support, but also to standardize some naming convention) and remove several unused macros. 10. Update ucc_geth.c to use the new macros. 11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol to use when initializing the UCC in ucc_slow_init(). 12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since these are the real names of the registers. 13. Use the setbits, clrbits, and clrsetbits where appropriate. 14. Refactor ucc_set_qe_mux_rxtx(). 15. Remove all instances of 'volatile'. 16. Simplify get_cmxucr_reg(); 17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[]. 18. Updated struct ucc_geth because struct ucc_fast is not padded any more. Signed-off-by:Timur Tabi <timur@freescale.com> Signed-off-by:

The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.

Previously, Soft_emulate_8xx was called with no implementation, resulting in build failures whenever building 8xx without math emulation. The implementation is copied from arch/ppc to resolve this issue. However, this sort of minimal emulation is not a very good idea other than for compatibility with existing userspaces, as it's less efficient than soft-float and can mislead users into believing they have soft-float. Thus, it is made a configurable option, off by default. Signed-off-by:

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. Signed-off-by:

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 following change makes it able to run with larger memory. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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:

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).
