Sampling time and sequence length, along with the vbat channel are
specific to the f4/f7, and can't be shared with the l1 and friends.
Pull them out to their own common file.
We extracted code out to the common files, but they weren't being
linked. This didn't matter in the past, as they were empty.
Fixes: 46d4103c stm32: flash: move wait_for_last to f2/f4 explicitly.
Fixes: https://github.com/libopencm3/libopencm3/issues/953
Turns out, there's lots of common code for flash. Pull up prefetch
on/off to start with, as there's only a single bit name different.
Pull up the definitions of common API functions too, starting with
flash_set_ws. Even if the implementations are different, things that
meant to be the same, should be defined centrally.
split spi stuff in three part:
- v1 : basic spi peripheral
- v1_frf : v1 spi with frf mode additional bit in spi_cr2 / spi_sr
- v2 : spi with variable datasize, fifo and other fancy stuff.
v1 maps to f1 chips
v1_frf to f2, f4 and l0,l1
v2 to f0, f3 and l4
This breaks spi_master_init API for v2 devices : function prototype from
common spi header used to be abused, with DFF bit reused for CRCL bit.
New v2 spi_master_init does not handle anymore CRCL bits, as it does not
usually mess with other crc configuration.
The stm32fx07 is common DesignWare IP, used in both STM32 and EFM32 chips.
Rename the files to make this more clear, and easier to use in other
targets.
The f1, f2, f4, l1 chip families have a similar "v1" i2c peripheral on board.
More recent f0, f3, l0, l3 chip families share another "v2" version of i2c.
This patch unifies headers and implementation for two types of i2c peripherals:
- rename: i2c_common_all.[ch] to i2c_common_v1.[ch]
- remove i2c_common_f24.h: extra I2C blocks are defined in specific headers
- use f3 i2c code as a basis for common "v2" i2c implementation
- add f0 i2c support: use "v2" i2c implementation
Tests:
- tested on a custom f0 board
- compile-tested both libopencm3 and libopencm3-examples for all stm32

This is common code for f0234, keep renaming files as has become standard, even
if it's a suboptimal solution. This doesn't rename the header which was not
renamed for f3.

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.
This unifies stm32f1, l1, and f4 convenience functions for adc. The code
should be useable for f2 and f37x as well, but that needs hardware for testing,
and there was no existing implementation. This is the reason for the
"adc_common_v1.c" name, as trying to put all the different families into the
common file name has become too cumbersome.
All of the deprecated routines have been dropped, they've been marked
deprecated for a very long time now, and porting them seemed unnecessary.
This has been tested on f1, l1 and f4 discovery boards, and is based on some
existing l1/f1 unification code from
https://github.com/karlp/libopencm3/tree/rme_l1_master
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.
