Add basically what's needed to have some minimal but usefull subset of
function for a timer: irqs, compare, period, out polarity, enable/disable
and start.
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 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.

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.
Sampling time and sequence length, along with the vbat channel are
specific to the f4/f7, and can't be shared with the l1 and friends.
Pull them out to their own common file.
the 2014q3 or later toolchains are now readily available, and we should
now just consider this a user problem. This gets us out of trying to
parse compiler help output and chasing our own tail.

They were originally used to make sure that the doxygen was generated
correctly, but that style is no longer necessary.
There may be more peripherals that can be "cleaned" like this, but let's
do them one step at a time, as we work on that area.
This shows what is _actually_ different for f7. A couple of option
bits, and a renaming of bit 7 of the status register, from Program
Sequence Error to Erase Sequence Error.
We keep the separate implementation of wait_for_last_operation, to meet
the "suggestions" of the reference manual to insert a DSB instruction.
Keeping the renamed bit/functions also requires us to keep separate
implementations of the flag clearing functions
Comments were not consistent, and this serves no purpose. There's no
reason to explicitly lock the flash first before unlocking. These bits
are simply set when the keys are written.
All the "f" type flash parts have an EOP flag, even if it's in different
bit positions. Add a header for this common functionality, and move
it's implementation to the existing common file.
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.
Instead of every "simple" target having their own duplicate file with
all the section mappings, just provide a single, simple,
"cortex-m-generic.ld" that works with our startup code and any simple
rom/ram system. This also drops the pointless copying of files all over
the place. Using -L flags properly is sufficient, and the standard file
is now in the root of the library already.
rcc_osc_bypass_enable and rcc_osc_bypass_disable have been copy/pasted
around for the last time! There's a compile bit to check for L0/L1, but
otherwise this is just code duplication for no gain.
Add clock config for the 25MHz crystal found on the discovery board.
Verified to work on the STM32F7-Disco.
