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
Pulls out duplicate calls from f0/rcc.c and uses the common version which
also means that f0 can use rcc_peripheral_enable() now which is in common
but not the old rcc versions.
Tested with a miniblink example on the l053 discovery board.
Only register definitions at this stage, no helpers.
Register definitions from RM0367r2, hopefully the biggest
superset of L0 parts.

Committed to binutils back in 2012, so even though it has no real impact, it at
least does the right thing for future compilers to make better decisions.

Fix regresion from 5d4437fe43aa68a28611e9a0aecc712833230304 where
somehow not all occurrences were replaced. I could swear it all
compiled when I was working on it :(

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.

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)

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.
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.)
