Toshiba TMPA900 config: Fix incorrect working area.
The Toshiba TMPA900 series (TMPA900/901) only has internal RAM regions
RAM-0 (16kB) and RAM-1 (8kB) which we can use as working area.
This is probably a copy-paste error from tmpa910.cfg, which has the
correct values and sizes for the TMPA910 series (TMPA910/911/912/913):
there are RAM-0, RAM-1, and RAM-2 (each 16kB).
Also, change "built-in RAM" to "internal RAM" to match what the
datasheet uses.

xscale: fix bug in xscale_receive()
The code in xscale_receive() that tries to skip invalid reads (i.e.
reads that don't have the DBG_SR[0] 'valid' bit set) seems to be
wrong, as it only looks at the first word's valid flag rather than
each word's own valid flag. Am I reading the code correctly? If so,
the attached patch should fix it.
If this looks correct, I'll generate a proper patch and commit message.

stm32f1x: use async algorithm in flash programming routine
Let the target algorithm be running in the background and buffer data
continuously through a FIFO. This reduces or removes the effect of latency
because only a very small number of queue executions needs to be done per
buffer fill. Previously, the many repeated target state changes, register
accesses (really inefficient) and algorithm uploads caused the flash
programming to be latency bound in many cases. Now it should scale better
with increased throughput.

stm32f1x: use register base instead of register offset
Access the different flash banks' registers using a bank specific register
base and a register specific offset. This is equivalent but feels more
natural.
Some accesses were discovered that maybe should not be hard coded to bank0
registers. Add a note about that.

Split armv7m_run_algorithm into two pieces and use them to reimplement it.
The arch_info parameter is used to keep context between the two calls, so
both calls must refer to the same armv7m_algorithm struct. Ugly but works

target: add async algorithm entries to the target type
On supported targets, this may be used to start a long running algorithm in
the background so the target may be interacted with during execution and
later wait for its completion.
The most obvious use case is a double buffered flash algorithm that can
upload the next block of data while the algorithm is flashing the current.

to verify flash, target must be halted, and this will (when the new halt sequence is implemented) require reseting the chip. if the target is reset after writing the lock words, then it will lock, hence the CRC will fail because it is not possible to read stuff from the target.
