On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete
bridges (mpc10x, tsi108) use the new for_each_compatible_node() or
for_each_node_by_type() to provide more exact matching when looking for
PHBs in the device tree.With the previous code it was possible to match on pci bridges since
we were only matching on device_type.Signed-off-by: Kumar Gala

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: Dale Farnsworth

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.

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.Signed-off-by: Scott Wood

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: Scott Wood

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).Signed-off-by: Scott Wood

The 8xx can only support a max of 8M during early boot (it seems a lot of

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: Scott Wood

These let board code set up pins and clocks without having to

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: Scott Wood
