Spencer Oliver 1c975fe30b cortex_m: target implementation renames cortex_m3 to cortex_m
We changed the actual target name quite a while ago.
This changes the actual target function names/defines to also match
this change.

Paul Fertser fccc55225a mdr32fx: support for Milandr's MDR32Fx internal flash memory
This adds example config and flash driver for russian Cortex-M3
microcontroller model.

Run-time tested on MDR32F9Q2I evaluation board; the flash driver
should be compatible with MDR32F2x (Cortex-M0) too but I lack hardware
to test.

There're no status bits at all, the datasheets specifies some delays
for flash operations instead. All being in <100us range, they're hard
to violate with JTAG, I hope. There're also no flash identification
registers so the flash size and type has to be hardcoded into the
config.

The flashing is considerably complicated because the flash is split
into pages, and each page consists of 4 interleaved non-consecutive
"sectors" (on MDR32F9 only, MDR32F2 is single-sectored), so the
fastest way is to latch the page and sector address and then write
only the part that should go into the current page and current sector.

Performance testing results with adapter_khz 1000 and the chip running
on its default HSI 8MHz oscillator:

When working area is specified, a target helper algorithm is used:
wrote 131072 bytes from file testfile.bin in 3.698427s (34.609 KiB/s)

This can theoretically be sped up by ~1.4 times if the helper
algorithm is fed some kind of "loader instructions stream" to allow
sector-by-sector writing.

Pure JTAG implementation (when target memory area is not available)
flashes all the 128k memory in 49.5s.

Flashing "info" memory region is also implemented, but due to the
overlapping memory addresses (resulting in incorrect memory map
calculations for GDB) it can't be used at the same time, so OpenOCD
needs to be started this way: -c "set IMEMORY true" -f
target/mdr32f9q2i.cfg

It also can't be read/verified because it's not memory-mapped anywhere
ever, and OpenOCD NOR framework doesn't really allow to provide a
custom handler that would be used when verifying.

George Harris 516719b6b8 Added SPIFI flash driver, algorithms, and docs
Added a flash driver designed to allow program/erase of
memory-mapped SPI flash chips for LPC43xx/LPC18xx family
micros. This driver includes three algorithms - erase,
write, and SPIFI peripheral initialization (to allow
memory-mapped access after a reset). The driver has been
added to the flash driver table (drivers.c), and the
OpenOCD documentation has been updated to include the flash
driver configuration command.

Spencer Oliver 94db77a0e6 flash: add stm32f2x async flash loader
This enable the stm32f2x flash driver to use the asynchronous
algorithm support.

Speed increase is as follows:
before - wrote 1048576 bytes from file stm32f4x.bin in 30.453804s (33.625 KiB/s)
after - wrote 1048576 bytes from file stm32f4x.bin in 23.679497s (43.244 KiB/s)

This also fixes a bug that was in the old flash loader.
The old loader waited while bit16 of the status reg was 0, the new
loader waits until this bit is 0 as stated in the flash spec.
Bizarrely this bug did not effect programming on any tested parts.

Andreas Fritiofson 92b14f8ca9 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.
