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.

3a7cbec7: stm32l/stm32f: name space standardization [BREAKING]
Recent debian testing and ubuntu 15.10 releases contain a
gcc-arm-none-eabi toolchain that returns 0 for the test with -mcpu and
-fsyntax-only, despite not actually supporting cortex-m7. They then
failed hard on actual compilation steps.
Use the --help=target output instead. tested with old g-a-e 4.7 and
newer releases.
Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
