ce5d1ca9a2 doc: restore targets as pages.
You can't have two mainpage items, and the second was just being
ignored.  This restores them, which makes the left side list longer,
which we may or may not like, but it's at least how it was documented to
be.

This drops a lot of now common definitions.  This is still just

b23dccc7ae stm32: flash: pull up prefetch to _all
Turns out, there's lots of common code for flash.  Pull up prefetch
on/off to start with, as there's only a single bit name different.

Pull up the definitions of common API functions too, starting with
flash_set_ws.  Even if the implementations are different, things that
meant to be the same, should be defined centrally.

b47b967440 doc: use common naming for peripheral apis
Only applied to STM32 doc trees at present.

Instead of declaring a group for "STM32blah" in the doc-blah.h files,
and then trying to put all the common+specific peripheral code into
those groups, (which is what led to the stub doxygen holder empty .c
files)  Just use a standard name like "Peripheral APIS" and place
everything into that.

Demonstrated by converting ADC and USART peripherals, which is
definitely not complete, but it shows how to make things less magical,
and less prone to copy/paste errors.  Now, you can copy/paste and it
will do the right thing, because everyone uses the same group names.

This is also how to unify the mix of "STM32blah->Periphblah" and _also_
the dangling "periph_file" modules in doxygen, it merges them together
properly, as they're intended to be really.

bf125e91f9 stm32: rework spi, based on PR #740 and #742.
split spi stuff in three part:
 - v1 : basic spi peripheral
 - v1_frf : v1 spi with frf mode additional bit in spi_cr2 / spi_sr
 - v2 : spi with variable datasize, fifo and other fancy stuff.

v1 maps to f1 chips
v1_frf to f2, f4 and l0,l1
v2 to f0, f3 and l4

This breaks spi_master_init API for v2 devices : function prototype from
common spi header used to be abused, with DFF bit reused for CRCL bit.
New v2 spi_master_init does not handle anymore CRCL bits, as it does not
usually mess with other crc configuration.

d1d511c6f4 stm32: rcc: add reset reason group flags.
Originally suggested in https://github.com/libopencm3/libopencm3/pull/399

At least provide macros for each family that allows easy masking of the
full set of reset reason flags.  Trying to provide a function that
provides these in random upper bits seems unclear at best.

ef91856ac1 stm32: unify i2c implementations
The f1, f2, f4, l1 chip families have a similar "v1" i2c peripheral on board.
More recent f0, f3, l0, l3 chip families share another "v2" version  of i2c.

This patch unifies headers and implementation for two types of i2c peripherals:

- rename: i2c_common_all.[ch] to i2c_common_v1.[ch]
- remove i2c_common_f24.h: extra I2C blocks are defined in specific headers
- use f3 i2c code as a basis for common "v2" i2c implementation
- add f0 i2c support: use "v2" i2c implementation

Tests:
- tested on a custom f0 board
- compile-tested both libopencm3 and libopencm3-examples for all stm32

da91794f52 stm32: rcc: Rationalize MCO definitions
Some parts used HSICLK, some used HSI.  Most used NOCLK, f3 used
DISABLED.  Try and move all to the shorter, simpler forms, instead of
having mixed defines for different targets for the same thing.  Just
because the bits themselves are different doesn't mean we should make it
more difficult for users to port code.

cf7d0a08ca stm32: rcc_wait_for_sysclk_status should actually wait
Original implementation only checked whether the user had _selected_ the
clock, not whether it had actually switched to the clock or not.  For
almost all cases, this made this function either a no-op, if you _had_
selected the clock, or a blocking loop if you hadn't selected it ahead
of time.

3a7cbec776 stm32l/stm32f: name space standardization [BREAKING]
As done by esden for the F4, remove typedefs and add prefixes to clock enums
This extends this to all stm32 families.

    Let's not hide the fact that these variables are structs/enums.

    We are filling up the namespace badly enough, we should be prefixing as
    much as we can with the module names at least. As users we already run
    often enough in namespace colisions we don't have to make it worse.

    * CLOCK_3V3_xxx enums renamed to RCC_CLOCK_3V3_xxx
    * clock enums (PLL, HSI, HSE ...) prefixed with RCC_
    * scale enum of pwr module prefixed with PWR_

c72f3d588a Surround all macro parameters with ()
All the macro arguments that are user supplied, or potentially, wrap properly
in () as good practice.

Probably missed one or two, and a lot of them are possibly unnecessary, but
it's straightforward to just do it always.

e121243ce2 usb: extract ST USB FS peripheral core. [BREAKING CHANGE]
The breaking changes here changes in header location, and changes in driver
name passed down to the usb stack.

Changes affect: stm32f102/f103, stm32l1, and some f3 parts

* instead of the confusingly generic "usb" use the name "st_usbfs" for the USB
  Full speed peripheral ST provides in a variety of their stm32 products.
  Include directives should change as:
      #include <libopencm3/stm32/usb.h> => <libopencm3/stm32/st_usbfs.h>

* instead of the confusingly specific "f103" name for the driver, use
  "st_usbfs_v1"  [BREAKING_CHANGE]

  Instead of:
    usbd_init(&stm32f103_usb_driver, .....) ==>
    usbd_init(&st_usbfs_v1_usb_driver, .....) ==>

The purpose of these changes is to reduce some confusion around naming, but
primarily to prepare for the "v2" peripheral available on stm32f0/l0 and some
f3 devices.

5d4437fe43 stm32/spi: Replace all SPIx_I2S_BASE with SPIx_BASE
Latest versions of all reference manuals refer to the address as SPIx_BASE, and
simply name some of the individual registers as SPI_I2SXXXX.  Likewise, the
interrupts are simply SPIx, not SPIx/I2Sx.  Rather than hacking more duplicates
into the F0 and L0 parts where this was turning up, remove the pointless _I2S_
from SPI2/SPI3 and make it all consistent

Compile tested only, with the examples collection.

There's more exti lines on many more devices now. F0 and F3 have extras, as did
L1 and L0.  There's no real reason not to have higher order EXTI definitions

7681597e42 Use type suffix to avoid warnings
When compiling with all warnings enabled, some defines can lead to
warning due to missing unsigned type suffix:

warning: integer overflow in expression [-Woverflow]

This fix should not affected behavior at all, since calculation with
such overflows lead to the same actual address when writing to that
location. However, it makes the warning disappear and also defines
the right data type for a memory location.

27bc12de61 stm32: unify bulk of adc convenience functions
This unifies stm32f1, l1, and f4 convenience functions for adc.  The code
should be useable for f2 and f37x as well, but that needs hardware for testing,
and there was no existing implementation. This is the reason for the
"adc_common_v1.c" name, as trying to put all the different families into the
common file name has become too cumbersome.

All of the deprecated routines have been dropped, they've been marked
deprecated for a very long time now, and porting them seemed unnecessary.

This has been tested on f1, l1 and f4 discovery boards, and is based on some
existing l1/f1 unification code from
