The common code wasn't being included in L1 builds, even though the headers now
included the correct definitions.
This combines the two f0 and f3 spi files, which previously differed only in
the number of spi peripherals defined.
Files were renamed to the full "l1f124" style, not because I like it, but
because it's the convention we have, so it's best to apply it rigourously.
Tested on L1 and F100 boards, compile tested only for others, but the examples
repository all compiles too. (Though the lack of SPI examples for all
platforms was how this broke in the first place)
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.

Because most changes are internal to a function in exti.c I am leaving
the macro checks in there, otherwise we would end up with a bunch of
code duplication if we used the dispatch system used otherwise
throughout the stm32 part of the library. I bet it could be split up
into more granular functions resulting in more generic code that we
could run through the dispatch system. But I am leaving that as an
excersize for later.
We don't support f0 yet so let's not fool anyone. We may rename those
files back again if when we cross check that it is actually true this
file supports f0.
- Makefiles of other stm32s updated accordingly.
- f3/rcc.c updated to some definition changes.
- f3/flash.c removed in order to use flash_common_f234.c to comply with new organization.
Added hash processor register definitions and main functions. Hash
processor is supported in stm32f21, stm32f41 and stm32f43 and can be
used to calculate Md5 and Sha1.
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.
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.
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.
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.
In the header:
- Fix DMA_SxCR_CT: change shift from 18 to 19
For use with the convenience functions:
- Added DMA_SxCR_CHSEL generic values
- Added DMA_STREAM - generic values
- Added dma_if_offset - rather than separating out LISR and HISR
- Added masks
- Added dma_disable_double_buffer_mode()
vector.o, nvic.o, scb.o and assert.o are available on every platform,
but at least some of them differ between the implementations. they
already got built explicityly on some platforms; now adding them to the
common Makefile.include.
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.
- 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.
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.
