version of gcc 4.x much more relaxed?

of a (NOR) flash chip: allow passing "last" as an alias
for the number of the last sector.
Improve several aspects of error checking while we're at it.

This patch modifies an error message which, in its original state,
I find somewhat unhelpful. So a small hint was added.

Erase logic:
- command invocation
+ treat "nand erase N" (no offset/length) as "erase whole chip N"
+ catch a few more bogus parameter cases, like length == 0 (sigh)
- nand_erase() should be static
- on error
+ say which block failed, and if it was a bad block
+ don't give up after the first error; try to erase the rest
- on success, say which nand device was erased (name isn't unique)
Device list ("nand list"):
- say how many blocks there are
- split summary into two lines
- give example in the docs
Doc tweaks:
- Use @option{...} for DaVinci's supported hardware ECC options
For the record, I've observed that _sometimes_ erasing bad blocks causes
failure reports, and that manufacturer bad block markers aren't always
erasable (even when erasing their blocks doesn't trigger an error report).

This patch adds target algorithm support for those flash devices that do not support DQ5 polling. So far they could only be programmed with host algorithm, but this was way too slow.

Optionally shave time off the armv4_5 run_algorithm() code: let
them terminate using software breakpoints, avoiding roundtrips
to manage hardware ones.
Enable this by using BKPT to terminate execution instead of "branch
to here" loops. Then pass zero as the exit address, except when
running on an ARMv4 core. ARM7TDMI, ARM9TDMI, and derived cores
now set a flag saying they're ARMv4.
Use that mechanism in arm_nandwrite(), for about 3% speedup on a
DaVinci ARM926 core; not huge, but it helps. Some other algorithms
could use this too (mostly flavors of flash operation).

Abstract the orion_nand_fast_block_write() routine into a separate
routine -- arm_nandwrite() -- so that other ARM cores can reuse it.
Have davinci_nand do so. This faster than byte-at-a-time ops by a
factor of three (!), even given the slowish interactions to support
hardware ECC (1-bit flavor in that test) each 512 bytes; those could
be read more efficiently by on-chip code.
NOTE that until there's a generic "ARM algorithm" structure, this
can't work on newer ARMv6 (like ARM1136) or ARMv7A (like Cortex-A8)
cores, though the downloaded code itself would work just fine there.

Almost innocuous; this is value is checked later, this
check being wrong would make it check stack garbage.

Also minor fixes for the message from "fill": the byte
count is unsigned, not signed; and more importantly,
print the real number of bytes written

- Bugfixes:
* internal osc: it's *12* MHz (not 15 MHz) on _current_ chips
+ except new Tempest parts where it's 16 MHz (and calibrated!)
+ or some old Sandstorm ones, where 15 MHz was valid
* crystal config:
+ read and use the crystal config, don't assume 6 MHz
+ know when that field is 4 bits vs 5
* an RCC2 register may be overriding the original RCC
+ more clock source options
+ bigger dividers
+ fractional dividers on Tempest (NYET handled)
* there's a 30 KHz osc on newer chips (for deep sleep)
* there's a 32768 Hz osc on newer chips (for hibernation)
- Cosmetic
* say "rev A0" not "vA.0", to match vendor docs
* don't always report master clock as an "estimate":
+ give the error bound if it's approximate, like "±30%"
+ else don't say anything
* fix whitespace and caps in some messages
* these are not AT91SAM chips!!
Those clock issues might explain problems sometimes reported when
writing to Stellaris flash banks; they affect write timings.
That 12-vs-15 MHz issue is problematic; there's no consolidated doc
showing which chips (and revs!) have which internal oscillator speed.
It's clear that only older silicon had the faster-and-less-accurate
flavor. What's less clear is which chips are "old" like that.
Lightly tested, on a DustDevil part.

OpenOCD was able to access only to chips attached to first EMIF
chipselect. This patch fixes chipselect management code and allows
OpenOCD to access to NAND devices attached to any EMIF CS line.

Warn when people (or scripts) use numeric identifiers for TAPs,
instead of dotted.name values. We want this usage to go away,
so that for example adding more TAPs doesn't cause config scripts
to break because some sequence number changed.
It's been deprecated since late 2008, but putting a warning on
this should help us remove it (say, in June 2010) by helping to
phase out old (ab)usage in config scripts.
Other than in various config files, the only code expecting such
a number was the almost unused str9xpec driver. This code was
changed to use the TAP it was passed, instead of making its own
dubious lookup and ignoring that TAP.
