[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.  :)

Paul Mackerras [Mon, 8 Oct 2007 23:59:17 +0000 (09:59 +1000)]
[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.

Paul Mackerras [Thu, 4 Oct 2007 04:18:01 +0000 (14:18 +1000)]
[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.

cascaded IRQ. This situation hangs MPIC on MPC8568E.

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()

[POWERPC] 85xx: Failure with odd memory sizes and CONFIG_HIGHMEM

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().

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.
