The breaking changes here changes in header location, and changes in driver
name passed down to the usb stack.
Changes affect: stm32f102/f103, stm32l1, and some f3 parts
* instead of the confusingly generic "usb" use the name "st_usbfs" for the USB
Full speed peripheral ST provides in a variety of their stm32 products.
Include directives should change as:
#include <libopencm3/stm32/usb.h> => <libopencm3/stm32/st_usbfs.h>
* instead of the confusingly specific "f103" name for the driver, use
"st_usbfs_v1" [BREAKING_CHANGE]
Instead of:
usbd_init(&stm32f103_usb_driver, .....) ==>
usbd_init(&st_usbfs_v1_usb_driver, .....) ==>
The purpose of these changes is to reduce some confusion around naming, but
primarily to prepare for the "v2" peripheral available on stm32f0/l0 and some
f3 devices.

on irc, and all those forgotten.
The f3 adc has separate bits for end of conversion and end of sequence.
Support those fully, with the regular enable/disable irq methods, and
the flag checking methods.
Discovered in github bug: #493
This code was copied from the f4, and blindly modified to make it seem
to work. The f3 has separate flags for EOC and EOS, it doesn't use a
second bit to configure what the EOC bit does.
Consequently, update the documentation to correctly indicate that the
EOC bits are only set per conversion.

-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.
Rename rcc_ppre1_frequency and rcc_ppre2_frequency to rcc_apb1_frequency and rcc_apb2_frequency
Also add rcc_ahb_frequency (although it is not set correctly in all cases) which will be fixed by
the rcc commits later. Also fixup the only use in the library of these variables, the USART code.
And fix the typos that resulted
Make l1 generic too
All methods in this file are in either
* common/gpio_common_all.c
* common/gpio_common_f0234.c
Those other files have better doxygen commentary, this file should never
have been added.
to remove variations, redundancies, add missing, fix errors. All c files
refer only to the dispatch style headers in /include/stm32. Those headers
#include memorymap.h and cm3/common.h. All references to
these are removed from the family specific headers. Ethernet untouched as
it appears incomplete.
Added dummy spi.c for F0/F3. Fix some doxygen anomalies.
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.
So that the navigation pane works correctly in browsers.
Some additional doc fixes put in where found (but many more still to go).
Added some dummy .c and .h files to bring the associated docs into line.
makefile changed to allow 'make html' as well as 'make doc' (the latter only does html anyway).
According to RM0090, page 301, paragraph 11.13.12 Note. (For F4, for F1 and F3 is it in the corresponding manuals)
The JSQR are filled always ending at SQR4 ie for those lists we must set this list:
(A) -> JSQ4 = A,
(A,B) -> JSQ3 = A, JSQ4 = B,
(A,B,C) -> JSQ2 = A, JSQ3 = B, JSQ4 = C,
(A,B,C,D) -> JSQ1 = A, JSQ2 = B, JSQ3 = C, JSQ4 = D,
The readed values are in correct order, starting from JDR1:
(A) -> JDR1 = A,
(A,B) -> JDR1 = A, JDR2 = B,
(A,B,C) -> JDR1 = A, JDR2 = B, JDR3 = C,
(A,B,C,D) -> JDR1 = A, JDR2 = B, JDR3 = C, JDR4 = D,
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.
- Additional frequency configuration (48Mhz, for usb use!)
- FLASH latency decreased (too unnecessarily low before)
- Rcc functions to change usb freq prescaler.
Very few functions can be shared (~ 3). A possible solutions is to move
i2c_common_all to i2c_common_f124, create i2c_common_all and move f3/i2c to i2c_common_f3. Who agrees?
- 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.
