Adds a flash driver for Nuvoton MINI51, MINI52 and MINI54 microcontrollers.
At the moment, it only supports the erase and write operations.
These microcontrollers have a 4 / 8 / 16 KB APROM for application code and a
2 KB LDROM for bootloaders. When the MCU has booted off the APROM, the LDROM
isn't mapped in memory but can be programmed, and the other way around.
This means that the ARM core is typically rebooted for programming. After a
successful write or erase operation, it is rebooted again, using the initial
boot source.
This driver only supports programming the APROM.
This driver is a pure JTAG implementation, it doesn't use any SRAM.
I've tested it on a MINI54ZAN microcontroller using an ST-LINK/V2. With the
microcontroller running at the default clock frequency of 22.1184 MHz, speed
seems to be around 1.1 KB/s.

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.

This patch adds flash programming support for internal flash of the

The "base" parameter of the "flash bank" command is now significant
for the lpc4300 variant and required to determine the bank number
parameter needed by the IAP routines.
NOTE: I could only program flash successfully when the chip is powered
with "P2_7" pulled low to put it in ISP mode. When running from flash
(and not the ISP ROM), the target fails to halt and the sector erase
fails. This is similar to the behavior I remember when trying out the

To burn, one to run. So I am not confident my config is set up correctly.

The em357 driver only supported one page configuration (192k in 96 2048k)
pages. This is fine for em357 chips since that's the size they have, but
ST's STM32W chips (pretty much the same) have different flash
configurations available (64, 128, 192, 256k). I can't find anywhere
that would indicate the size of the chip anywhere in memory so the
selection must be manual, using the 'size' parameter. For backwards
compatibility, any size not known to be in use defaults to the 192k
configuration. I don't have any em357 devices to test, but I also found
that I had to re-assert the FPEC clock enable before performing an
erase. This is a single line and shouldn't break any configurations.
My testing so far has only been with a 64k device with 8k of RAM.
