- RP2040 show both DPs
- Multidrop test with STM32L552 and STM32H745 allows selection
with "-m 0x4500041" (H7), "-m 1" (L552) or "-m 0x01002927" (RP2040)
This adds support for the STM32WL series in stm32l4.c. These parts have
the same flash registers layout as the L4 series, but a different base.
Since there are already two sets of registers in this target file, this
adds support for register maps that can be customized for each device
ID.
This adds a TRY_CATCH around the adiv5_ap_read_id() in
adiv5_component_probe() and resets the DP when that happens.
It seems like the STM32WLE5 comes with the AP of the inactive core
enabled in a way that does not make it detectable, and the current code
times out and leaves the whole device hanging.
Catching the timeout and calling adiv5_dp_abort() seems to restore the
device to a useable state.
Tested on Seed LoRa-E5 (STM32E5JC).
STM32WLE5 has the same dual core chip as STM32WL5. For the second
core, the additional AP can be see, but access to e.g. CIDR0 for that
Romtable fails.
Aborting the scan too if again the second read of CIDR0 fails makes
sense anyways!
This adds support for the NXP S32K148. This is an automotive-grade part
that is derived from the Kinetis line, so it has a very similar
interface to other parts in the family.

**Summary**
Modifications to fix flash support on the lpc546xx:
- fix IAP entrypoint to be `0x03000204`, not the value at that address
- add a reset and attach sequence before erasing flash sectors. there's
little documentation around this, but experimentally, erasing sector 0
fails when the ROM bootloader is mapped to it (on reset). stepping the
chip once and attaching is enough to snap the chip out of it, permitting
flash erase on sector 0.
- add a few test commands to the lpc546xx table (read_uid, erase/write
sector, etc).
- write the magic CRC value when writing to sector 0
(`lpc_flash_write_magic_vect`).
- move the lpc546xx probe to before the lpc43xx probe, to prevent
getting the lpc546xx into Lockup when reading an illegal memory location
during lpc43xx probing
Fixes#786.
I don't 100% understand the reset/load sequence of this part, but these
changes are sufficient to program and debug the part now.
I didn't do a detailed analysis of what pyocd (via st-link hardware
adapter) and segger jlink do to handle the same, but both of those
worked without modification, so there's some difference in the
sequence they're using.
**Testing**
Verified I can now successfully erase and write an executable in sector
0 (and other sectors).
Verified the new commands work correctly.
Especially needed when leaving the debugger or during debug unit power-up.
ARM Debug Interface Architecture Specification ADIv5.0 to ADIv5.2
tells to clock the data through SW-DP to either :
- immediate start a new transaction
- continue to drive idle cycles
- or clock at least 8 idle cycles
Implement last option to favour correctness over slight speed decrease
Implement only for adapters where we assemble the seq_out_parity in our code,
as on firmware, ftdi and jlink. Hopefully the high level adapters do it right.

It seems, writing to DHCSR fails silent when the device is sleeping.
Reading DHCS during sleep may return nonsense.
Repeated write may at some point catch the device running and succeed.
With devices sleeping for long time and running on faster clock the
chance for a successful hotplug gets smaller.
- Try hard to halt a sleeping device
- Prepare vector catch and enable all debug units by TRACENA
- Release reset
- Apply device specific fixes
-- STM32F7: Store old value of DBGMCU_CR, enable debug in sleep in
DBGMCU before reading PIDR and restore DBGMCU on detach.

* stm32h7: Don't tc_printf from flash functions
Receving an 'O' packet while flashing confuses GDB and then
weird stuff happens.
* Replace tc_printf with DEBUG_WARN
