Was completely undocumented before. Just needed different tagging so it
could be picked up.
No attempt at this stage of sharing more code between the cmu modules.
gpio_common was built, but wasn't picked up by any documentation.
Use the peripheral_apis style from stm32, but try out the #pragma once
style. Downside is you don't get warnings if you include an sub layer
.h file. Upsides are
* no ifdef/endif blocks
* no /**@cond*/ /**@endcond*/ blocks
* that's enough win!
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.

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.

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.
Somewhat replaces some earlier work done by hg/lg, but much more
complete, so we kept it as is, because it's bringing in even more parts
after this.

Renamed every instance of variable CFLAGS in target specific Makefiles
to TGT_CFLAGS to free up CFLAGS for user defined compiler flags.
Added information in README.md about existence and usage of CFLAGS
environment variable in build process.
-ggdb3 make slightly bigger .elf files, but allows gdb to understand
macros, which libopenocm3 uses somewhat extensively. Make this the
default, and pull it up to the common base makefile, so it can be easily
substituted.
On linux, the output of CP rule was try to write to / which is - of course, forbidden for write.
This solution adds to each part of lib correct pointer to the root of lib where the libs should be written.
Bug found by Kuldeep Singh Dhaka.
We currently default to "-mfloat-abi=hard -mfpu=fpv4-sp-d16" for M4F cores, and
and variations of "-mfloat-abi=soft" for the others. Keep the M4F default, and
move others to no FP flags for consistency, but allow overriding these flags
via the FP_FLAGS environment variable.

This also report bug fixes about data alignment and bss storage to EFM32 &
LM3S targets.
