stm32f103_rey6: implement std periph driver

[thomaseichinger]

Implement peripheral driver for timer introduced by @haukepetersen
needs accompanying PR OlegHahm/thirdparty_boards#18 to work

[OlegHahm]

Needs rebase.

[thomaseichinger]

rebased and updated to newest version in RIOT-OS/RIOT#614

[OlegHahm]

use HWTIMER_MAXTIMERS instead of ARCH_MAXTIMERS

[OlegHahm]

I get

timer.c: In function `timer_init':
timer.c:85:14: error: `TIMER_1' undeclared (first use in this function)
         case TIMER_1:

and so on.

[thomaseichinger]

I updated RIOT-OS/thirdparty_board#18 to be consistent with this PR an fix the TIMER_1 missing definition.
This current implementation of the timer is kind of all in though hwtimer doesn't make use of the second timer right now. This could maybe be changed in the future.

[thomaseichinger]

updated addressing ARCH_MAXTIMERS

[OlegHahm]

Use RIOTBASE

[OlegHahm]

Now I get repeated

timer.c: In function `timer_init':
timer.c:65:5: warning: enumeration value `TIMER_UNDEFINED' not handled in switch [-Wswitch]
     switch (dev) {

[haukepetersen]

This you get because the timer driver interface was changed, an TIMER_UNDEFINED was added to the type struct...

[thomaseichinger]

updated handling TIMER_UNDEFINED, s/MAKEBASE/RIOTBASE/g in Makefile and rebased

[LudwigKnuepfer]

Is this in a working condition?

[thomaseichinger]

yes it is

[LudwigKnuepfer]

@haukepetersen can you please review this?

[thomaseichinger]

@haukepetersen any comments or may I squash?

[haukepetersen]

How about a consistent indention?!

[haukepetersen]

Ok, just these 2 minor remarks. I do not have an STMf10x board here - so I trust you that it is working. If you'd address these two things I give an ACK.

[thomaseichinger]

updated addressing @haukepetersen's comments and adopted to renaming from active_thread to sched_active_thread.

[haukepetersen]

ACK

[thomaseichinger]

squashed and GO
