[POWERPC] Make clockevents work on PPC601 processors
In testing the new clocksource and clockevent code on a PPC601
processor, I discovered that the clockevent multiplier value for the
decrementer clockevent was overflowing. Because the RTCL register in
the 601 effectively counts at 1GHz (it doesn't actually, but it
increases by 128 every 128ns), and the shift value was 32, that meant
the multiplier value had to be 2^32, which won't fit in an unsigned
long on 32-bit. The same problem would arise on any platform where
the timebase frequency was 1GHz or more (not that we actually have any
such machines today).
This fixes it by reducing the shift value to 16. Doing the
calculations with a resolution of 2^-16 nanoseconds (15 femtoseconds)
should be quite adequate. :)

[POWERPC] Prevent decrementer clockevents from firing early
On old powermacs, we sometimes set the decrementer to 1 in order to
trigger a decrementer interrupt, which we use to handle an interrupt
that was pending at the time when it was re-enabled. This was causing
the decrementer clock event device to call the event function for the
next event early, which was causing problems when high-res timers were
not enabled.
This fixes the problem by recording the timebase value at which the
next event should occur, and checking the current timebase against the
recorded value in timer_interrupt. If it isn't time for the next
event, it just reprograms the decrementer and returns.
This also subtracts 1 from the value stored into the decrementer,
which is appropriate because the decrementer interrupts on the
transition from 0 to -1, not when the decrementer reaches 0.

[POWERPC] Fix performance monitor on machines with logical PVR
Some IBM machines supply a "logical" PVR (processor version register)
value in the device tree in the cpu nodes rather than the real PVR.
This is used for instance to indicate that the processors in a POWER6
partition have been configured by the hypervisor to run in POWER5+
mode rather than POWER6 mode. To cope with this, we call identify_cpu
a second time with the logical PVR value (the first call is with the
real PVR value in the very early setup code).
However, POWER5+ machines can also supply a logical PVR value, and use
the same value (the value that indicates a v2.04 architecture
compliant processor). This causes problems for code that uses the
performance monitor (such as oprofile), because the PMU registers are
different in POWER6 (even in POWER5+ mode) from the real POWER5+.
This change works around this problem by taking out the PMU
information from the cputable entries for the logical PVR values, and
changing identify_cpu so that the second call to it won't overwrite
the PMU information that was established by the first call (the one
with the real PVR), but does update the other fields. Specifically,
if the cputable entry for the logical PVR value has num_pmcs == 0,
none of the PMU-related fields get used.
So that we can create a mixed cputable entry, we now make cur_cpu_spec
point to a single static struct cpu_spec, and copy stuff from
cpu_specs[i] into it. This has the side-effect that we can now make
cpu_specs[] be initdata.
Ultimately it would be good to move the PMU-related fields out to a
separate structure, pointed to by the cputable entries, and change
identify_cpu so that it saves the PMU info pointer, copies the whole
structure, and restores the PMU info pointer, rather than identify_cpu
having to list all the fields that are *not* PMU-related.

[POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascading
set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.
To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.
Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).
qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.

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

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

parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't

[POWERPC] cpm2: Infrastructure code cleanup.
Mostly sparse fixes (__iomem annotations, etc); also, cpm2_immr
is used rather than creating many temporary mappings.

[POWERPC] 8xx: Set initial memory limit.
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.

[POWERPC] 8xx: Work around CPU15 erratum.
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.

[POWERPC] 8xx: Add pin and clock setting functions.
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.

[POWERPC] 8xx: Infrastructure code cleanup.
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.

[POWERPC] 8xx: Fix CONFIG_PIN_TLB.
1. Move CONSISTENT_START on 8xx so that it doesn't overlap the IMMR mapping.
2. The wrong register was being loaded into SPRN_MD_RPN.
