Uwe Hermann f1a6e56f5c gpio: Fix some issues with gpio_set_mode().
This patch, a slightly modified version of a patch from Thomas Otto,
should fix the following two issues:

 - It generally sets the submited config to the mentioned GPIO pins but
   kills configs for other pins on the same GPIO port. So if we want to set
   PB6 and PB7 to push-pull and I2C2 SDA and SCL (PB10 and PB11) to open
   drain it's simply impossible, because the second config try kills the first.

 - The floating-bit thing isn't working correctly. If we enable a config
   for PB6 for instance, the same config will also apply to all following
   pins of that port (i.e. PB7-PB15). That's because the shifting isn't only
   done if a pin isn't to configure, if you are hitting a matching bit the
   shiftig is missing. I think shifting isn't nessessary for a separate
   variable. We have the counting index from the for statement.

Both issues should now be fixed.

README
------------------------------------------------------------------------------

The libopenstm32 project aims to create an open-source firmware library for
STM32 microcontrollers.

It is written completely from scratch based on the STM32 datasheets,
programming manuals, and application notes. The code is meant to be used
with a GCC toolchain for ARM (arm-elf or arm-none-eabi), flashing of the
code to an STM32 device can be done using the OpenOCD ARM JTAG software.


Status and API
--------------

The libopenstm32 project is currently work in progress. Not all subsystems
of the STM32 are supported, yet.

IMPORTANT: The API of the library is NOT yet considered stable! Please do
           not rely on it, yet! Changes to function names, macro names etc.
           can happen at any time without prior notice!

Building
--------

 $ make

You may want to override the toolchain (e.g., arm-elf or arm-none-eabi):

 $ PREFIX=arm-none-eabi make

For a more verbose build you can use

 $ make V=1


Example projects
----------------

The library ships with a few small example projects which illustrate how
individual subsystems of the SMT32 can be configured and used with
libopenstm32.

For flashing the 'miniblink' example (after you built libopenstm32 and the
examples by typing 'make' at the top-level directory) you can execute:

 $ cd examples/miniblink
 $ make flash

The Makefiles of the examples are configured to use a certain OpenOCD
flash programmer, you might need to change some of the variables in the
Makefile if you use a different one.


Installation
------------

 $ make install

This will install the library in /usr/local. If you want to install it
elsewhere, use the following syntax:

 $ DESTDIR=/opt make install


Coding style
------------

The whole library is programmed using the Linux kernel coding style, see
http://lxr.linux.no/linux/Documentation/CodingStyle for details.

Please use the same style for any code contributions, thanks!
