5c14780403 [build] Remove PyYAML dependency
This converts all the YAML files to JSON files, as json parsing is built
into python instead of being a separate library requiring installation.

YAML is a superset of JSON, but putting comments in is not quite as obvious
as it is in yaml.

The following glue was used to convert yaml to json:
python -c 'import sys, yaml, json; json.dump(yaml.load(sys.stdin), sys.stdout, indent=4)' < $1 > $2

Clearly I haven't tested this on every single platform, and this
doesn't address the large blobs of yaml in the lpc4300 scripts directory,
only the cortex NVIC generation process.

I've tested a few IRQ driven example apps, and I've checked the generated
output of some known cases like the LM3s that has explicit gaps, and they are
all generated correctly.

638eeebeec [stm32] Add Factory Calibration values where available
Add memorymap entries for ST calibration data, the vref internal, and the temp
sensor at 30C and 110C for the parts that provide this data.

F1 and F2 do not appear to have this anywhere.

8e44177a66 [stm32] SPI includes got jumbled for for DFF
DFF exists at bit 11 for f1, f2, f4 and l1, but the f0 and f3 have that bit as
CRC len and use CR2 for data size bits instead.  The merging of the F3 and F0
and attempts to put common data in common places broke the l1 code.

F3 and F0 SPI headers are still almost completely identical.

a99f4fb620 [stm32] Use correct offsets for UniqueID bits
STM32L1 has a different set of offsets, not just a different base
address, so we can't have common registers definitions.  Also, out of
F0,F1,F2,F3,F4,L1, only the F1 has the odd note about 2x16bit registers
and 2x32bit registers with one 16bit register marked as "This field
value is also reserved for a future feature."  Therefore, replace the
awkward reading out as multiple words and just copy them in.

F0,F2,F3,F4 were missing definitions altogether.

This does _not_ attempt to address the problem of the mismatched base
addresses for Medium+ and High Density L1 parts.

7df63fcae0 First coarse run to fix coding style in locm3.
Added --terse and --mailback options to the make stylecheck target. It
also does continue even if it enounters a possible error.

We decided on two exceptions from the linux kernel coding standard:
- Empty wait while loops may end with ; on the same line.
- All blocks after while, if, for have to be in brackets even if they
  only contain one statement. Otherwise it is easy to introduce an
  error.

Checkpatch needs to be adapted to reflect those changes.

69902568d1 [stm32-l1] Turn on the DMA code.
It appears to be the same dma peripheral as in the F1 and F3, so just
enable it as is.

5b8953124e This mainly moves the STM32 timers' code to the common area.
F2 and F4 have a common section to deal with the options register (TIM2 and TIM5 only)
L1 has been made common with timer_common_all as its options register has very different settings to F2/F4. Code is in the L1/timer.c L1/timer.h files

Note that F3 and F05 timers should fit into this scheme, with F3 having additional features.

Bundled with this is L1/pwr.h to change a documentation setting
Also all the Doxyfiles have added "ENABLE_PREPROCESSING = NO" to fix a problem introduced by commit 118.

e2022f5884 Repair to documentation (most documented files)
to remove errors, duplications and inconsistencies.
File lib/stm32/f1/pwr.c - all code removed as it duplicates that in common/pwr_common.c
Remaining changes do not affect code. Compiles OK.
TODO efm32 has no code so generates no modules
TODO F2 needs pwr.c
TODO L1 needs dma.h and dma.c

d9fb4f7401 Add examples making use of the RTC
Add an example using the RTC to help with a lower power design.  This is
a sister example to the existing "button-irq-printf", which is
functionally identical, but uses far less power.

There's more tricks that can be done to lower the power even further,
but this shows a few of the early steps that can be done, using the RTC
wakeup instead of a timer.

e5b3250382 [stm32] Support the "new" BCD style RTC peripheral
Add the register definitions and some of the most basic helper functions
for the new style BCD RTC module found on the F2, F4, L1, F3 and F0.

This tries to keep as close to HACKING_COMMON_DOC as possible, while
maintaining sane names.

df5e3e5ff1 [l1] PWR: fix style for common code
Code added for L1 to support the PWR Control block didn't properly
follow the HACKING_COMMON_DOC guidelines.  The naming was wrong, and
some headers were missing.  This commit has no functional changes, it
only addresses the style and structure problems.

7ec382c7d5 STM32: Moved SPI code into the common area.
Updated the documentation so that it appears in all families
Also added it to the L1 area, but is untested. An addition to the memorymap
allows commonality and a #ifdef added to the spi_common_all code to
exclude the case of SPI3 for L1 and F0 as SPI3 doesn't exist in those.
An rcc dispatch header was added to remove same code from the spi header.

df1808e2dc [l1] Add rcc clock setup helper routines
Despite the L1 being a low power device, my initial focus is on making
it basically compatible with existing devices.

To that end, provide clock setup helper routines that configure it for maximum performance,
allowing some similar clock speeds to F1 devices to help with testing. This requires adding
the power chipset routines to set the voltage range.

Clock setup style is similar to the F4 code, which seems nicer than the overflow of different
routines used on the F1 code.

NOTE: Both the F4 existing pwr code, and this code don't actually include the f1 core power
code, even though it should be compatible
