Regular rng peripheral, with one additional bit : clock error detection
apparently available on l4 chips). Curiously, Clock error detection is
_disabled_ when bit is set, but bit is cleared by default, so peripheral
/ clock error detection behaves like all other chips..
NB: RNG need proper rcc_ccicr_rngsel bits set to work, no clock is set by
default. Note also that on that chip fRNGCLK must be higher than fHCLK/32
doxygen really wants the @defgroup _and_ the @addtogroup to both have
the full name, matching identically, to avoid all warnings.
Standardize on the "CAPS_PERIPH peripheral API" style.
The nvic_ functions all had a broken link to an f1 list of irqs. Change
the header generator to generate a fixed name, and link to them.
Because of their scoping, this ok, they find the correct family's irq
definitions.
The leading - makes it rather inconsistent with the majority of other
projects around the world. Use the form everyone else uses.
To solve this, properly pass prefix to inner makes as was always
intended.
Fixes: https://github.com/libopencm3/libopencm3/issues/1058
* Include the doc-swm050.h core file that defines the base groups.
* Fix/tweak groupings to make things consistent with other targets.
* Drop redundant type information. That's all included from the function
signatures automatically by doxygen.
* Added register descriptions from datasheet.
SWM050 is a series of MCU made by Foshan Synwit Tech. It contains a
Cortex-M0 CPU core, 8KiB of Flash and 1KiB of SRAM. The only peripherals
are GPIO, Timer and WDT. There's only two parts in this series, with
either TSSOP-8 or SSOP-16 packages.
This commit introduces the interrupt vector and GPIO support for them.

Allow for the high frequency clock that controlls things such as the
main CPU to be switched over to USHFRCODIV2. This is a 24 MHz PLL
that is trimmed using clock recovery from the USB signal, and is
accurate to within 1% of 24 MHz.

FLASH_CR_OPTSTRT needs to be written to FLASH_CR, and there is no reason
to mask the last two data bits.

(original code appeared to be badly copied from the flash_common_f24 codebase)
According to RM0351 and RM0394 flash needs to be programmed by double words.
Also fix flash_program() which was wrong anyways.

48Mhz has no purpose other than to be a naiive method of haivng working
USB. 120MHz never had any purpose, other than to match the f2 code it
was copied from. Drop them both. Remaining configs are all max speeds
for various F4 parts. Lower speeds are all custom
Some families had partially moved to peripheral api, and others were
only documenting common code, but not specific code. Delete dummy .c
files, and check that all specific apis are also being documented, not
just common apis.
