af9302d2b0 Merge some more RCC related #defines contributed by Federico Ruiz-Ugalde. 
Addition of remaining (mostly "connectivity line" STMs related) #defines
was done by me.

2c1fa8bd67 Partial merge of RCC support work contributed by Federico Ruiz-Ugalde. 
For now, this adds a bunch of #defines, double-checked against the
datasheet by me (added a few missing values for "connectivity line" STM32s).

3262983d27 Add initial GPIO API implementation. 
This currently includes a number of basic functions. Example usage:

 gpio_set_mode(GPIOC, GPIO_MODE_OUTPUT_2_MHZ,
               GPIO_CNF_OUTPUT_PUSHPULL, GPIO12);
 gpio_set(GPIOB, GPIO4);
 gpio_clear(GPIOG, GPIO2 | GPIO9);
 gpio_toggle(GPIOA, GPIO7);
 reg16 = gpio_port_read(GPIOD);
 gpio_port_write(GPIOF, 0xc8fe);

915d5bff90 Implement the simplest possible (working) blinking LED example application. 
This is the first working example code which is tested on hardware.
The LED on the Olimex STM-H103 eval board is happily blinking.

We use a dummy "delay" function (basically a busy-waiting for-loop), which
will only work if you use -O0 in CFLAGS (-O2, -O3, or -Os will not work as
the compiler optimizes the loop away).

We use some arbitrary value for stack size (2 KB) and use main()
directly as the reset vector function. This will change later.

Also, we do the GPIO and clock init as well as the GPIO toggling for the
LED blinking fully "manually" for now, but there may be more higher-level
functions for doing that at some later date.

10890b3f15 Don't use OpenOCD's "resume" command, only "reset" will work correctly. 
Also, make the 'flash' target depend on 'images'.

  CC      blink.o
  LD      blink
  INSTALL headers
  INSTALL lib

$ make clean
  CLEAN   blink.o
  CLEAN   blink

0efee48451 Add first example project (framework) using libopenstm32. 
This is intended as a small blink example for the Olimex STM32-H103 board.
It doesn't do anything useful (yet), but it builds fine.

There's a sample Makefile and a preliminary ld script (which probably
needs some more work).
