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.
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.
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.
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).
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.
- 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.
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!
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?
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.

Changed the license to LGPL3+ for some makefiles that got ommited in the
previous big patch commit.
Corrected a find and replace error in a linker file.
This fixes a problem where the linker included some padding
bytes between the end of the .text section (_etext) and the
start of the .data section.
The C runtime copies from _etext, so all static initialised data
was corrupted. This change forces the .data section to be written
at _etext to avoid this problem.
