Add initial memorymap for Vybrid VF6xx module. Also add the clock
control module which allows to control system clocks and enable
clocks of individual pheripherials.
Set Vector Table Offset to memory location of our vector table.
Since we put the whole programm including the vector table into
memory, we need to make use of the Cortex-M4 system control block
Vector Table Offset Register (VTOR).
Freescale Vybrid is a familiy of ARM SoC, wheras the VF6xx models
have two cores in one SoC, a Cortex-A5 and a Cortex-M4. This adds
initial support for the Cortex-M4 in the libopencm3 library.
By using two different ram areas (pc_ram and ps_ram) the user can
put the code in a RAM area bounded to the code bus. The data can
be stored in the data area. However, currently the initial values
of for the variables in the data section are stored in the code
section and copied to the ram section by the initialization code
(like it's copied from ROM to RAM on microcontrollers).
Fix regresion from 5d4437fe43 where
somehow not all occurrences were replaced. I could swear it all
compiled when I was working on it :(

This moves the platform specific initialization function pre_main
in front of C++ constructors. This is especially necessary for
platforms which need to setup the stack pointer (pre_main itself
is inline, hence no stack needed for this function).
Latest versions of all reference manuals refer to the address as SPIx_BASE, and
simply name some of the individual registers as SPI_I2SXXXX. Likewise, the
interrupts are simply SPIx, not SPIx/I2Sx. Rather than hacking more duplicates
into the F0 and L0 parts where this was turning up, remove the pointless _I2S_
from SPI2/SPI3 and make it all consistent
Compile tested only, with the examples collection.

Fixes#331Fixes#347
When full path of a source directory has spaces in it, that makes
shell and Make split the path, so special treatment is
necessary. Additionally, @F doesn't honour the escaping, so has to be
avoided.

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.
The CCxP/CCxNP bits are actually separated by a reserved bit, so the
correct mask is 0xa, (0b1010) not 0x6 (0b0110)

In a composite device if one want to separate code
for each interface, usbd_register_set_config_callback
can now register more than one callback.

GPIO pins should be configured for Analog IN on virtually all families
to reduce parasitic consumption.

This commit has been based on kuldeepdhaka's pioneer work, but it was reformatted to apply libopencm3 inclusion tree correctly.
timer_common_all.c now supports new rcc_periph_reset_pulse function for all families.
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.
When compiling with all warnings enabled, some defines can lead to
warning due to missing unsigned type suffix:
warning: integer overflow in expression [-Woverflow]
This fix should not affected behavior at all, since calculation with
such overflows lead to the same actual address when writing to that
location. However, it makes the warning disappear and also defines
the right data type for a memory location.
Extension of code for STM32F1 to allow for dual bank series XL.
Small changes to documentation for F2, F4 and L1 to add a parameter reference.
Tested with STM32F103RBT6
(note: tests show that the PG bit must be cleared after programming, otherwise
a subsequent erase attempt fails. This has been added to flash_program_half_word
for F0 and F1 only. A fix for the other families is not included in this PR.)
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
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).
