7d0611609b Code changes to stm32f1 adc.c and adc.h
remove rcc_set_adc_clk - use rcc version
Added functions:
 - adc_power_on
 - adc_start_conversion_direct
 - adc_set_dual_mode
 - adc_eoc
 - adc_eoc_injected
 - adc_read_regular
 - adc_read_injected
 - adc_set_injected_offset
Tested dual mode scanned regular, but no tests of injected yet.
Changes: "discontinuous" was misspelled.
 - adc_set_discontinuous_mode_regular - added "length" parameter
 - adc_disable_discontinuous_mode_regular - name change
 - adc_enable_discontinuous_mode_injected - name change
 - adc_enable_automatic_injected_group_conversion - disable triggers
 - adc_enable_jeoc_interrupt - name change to match common usage in lib
 - adc_disable_jeoc_interrupt - ditto
 - adc_enable_external_trigger_regular - remove incorrect test on parameter
 - adc_enable_external_trigger_injected - ditto
 - adc_set_sample_time - name change to match function's purpose
 - adc_set_conversion_time_on_all_channels - ditto
 - adc_set_injected_sequence - changed order of register loading (ref Barlow's issue)
 - adc_enable_analog_watchdog_on_all_channels - flipped AWDSGL
 - adc_enable_analog_watchdog_on_selected_channel - ditto
added aliases for expected commonly used functions to avoid sudden user code breakage

In adc.h, corrected errors in SQR names
added "deprecated" compiler warnings to adc_on and to aliases defined in adc.c

a69d83d312 unified vector table initialization
the cortex generic interrupts get moved to lib/cm3/vector.c, the
platorms' individual irq names, initialization and handler prototypes go
to platoform specific irq.h files.

as the vector.c file heavily depends on platoform specific headers, it
can't be built once-and-for-all in lib/cm3/, so there are inclusion
stubs in the various architecture dirs; this might be better solved with
Makefile / include path handling.

one particular file is lib/lpc43xx/vector.c; that platform's
initialization code contains an additional section to copy everything
from flash to ram (which probably performs better there). that code
still resides in the inclusion stub, and gets mashed in using defines.
would need a cleaner implementation together with the Makefile solution.

this commit contains some files of the upcoming efm32 branch, from which
it was cherry-picked.

the .bin files produced from before and after this commit only differ in
lpc43xx, where the startup sequence was subtly modified.

fc4047e4b4 Add assert macros to aid in debugging.
Adds libopencm3/cm3/assert.h header that provides assertion check macros
similar to those provided by the standard C library.

Thanks to Nicolas Schodet for help.

74cd991e7e Use a specific symbol for data source address in flash
That way, data source address does not depend on any other unrelated change in
linker script.

This also fixes cases when .data input section is aligned on 8 bytes.  The new
version does not provide any address for the output section so that it is
aligned to the strictest input section.  The _data_loadaddr symbol will
always take this alignment into account.

acc276a612 ADC documentation added
In adc.h additional defines needed to assist documentation - lines 172-191
added, and 384,436-451 are duplicates of earlier defines to complete
parameter sets (compiler has no trouble with these).

Minor doc corrections to other files.

No code changes (apart from additional defines).

52533a6e3d STM32F1xx: Changed markup to get more control over documentation, each
file having its own group module rather than using @file.

No code changes except for the following:

gpio: Added function to map the eventout signal plus two Remap functions
dma: Prevent changing base addresses while channel enabled (see datasheet)
pwr: Added pwr.c (new file)
timer: Removed the last function that I introduced recently; there is already
an equivalent function present. Changed some parameter names for consistency.

3441bba1c4 Changed local build target for library and linker files.
- The library files are now being built into the lib subdirectory of the
  source.
- The linker files for each library are being copied into the lib source
  subdirectory.

Motivation: The relative locations of files in the source directory after make
are now the same as after make install now. This makes it easier to
reuse examples with their makefiles outside of the libopencm3
sourcecode directory.

52fd7c7976 STM32F timers. Doxygen markup added, and some code changes:
1. Remove the extra mask (TIM_DIER(timer_peripheral) & flag)
in timer_get_flag. Not all flags in SR relate to IRQs and the flags that
do might be useful even if interrupts not enabled.

2. In a number of functions (e.g. timer_set_output_idle_state) that only
apply to advanced timers, add test for TIM1 and TIM8, as done in some others.

3. Added timer_force_event to manipulate the EG register

TBD DMA burst - can't get my head around why this would be useful.
Someone must have thought so!

450c3e00a1 Basic helper routines for CRC
Note, the CRC block is pretty useless for interoperability.  It only operates on 32bit
chunks, and in a different bit order.  No attempt to make full helpers for compatibility
with other implementations has been done.

71a3a7f2b1 Add Device Electronic Signature support.
Working unique id support, but not 100% convinced that this is the "least surprise"
path.  ST's docs provide the bits from low to high, in 2xu16 and 2xu32.
But to get it back as a "u96" the highest bits should be first?

12a73ce052 Use ODR instead of IDR to toggle an output GPIO
IDR represents the level on pin input while ODR is the value requested by the
programmer. This makes a difference for example when using the output as open
drain.

bf65589183 Support for exception handling in linker scripts.
This is needed even in plain C when 64 bit variable (e.g. long long int)
arithmetic is used. For example it is required when newlib is compiled with
--enable-newlib-io-long-long.
