Kevin O'Connor 886530e777 stm32: Explicitly reset peripheral clocks on stm32f1 
It appears some bootloaders do not properly reset some peripherals.

clearchris f87e29c775 armcm_boot: Additional code for broken bootloaders 
Explicitly disable the SysTick interrupt and explicitly set the stack
pointer, as some bootloaders aren't handling this correctly.

Kevin O'Connor 121249c999 stm32: Revert "stm32: performance improvement for spi on stm32f0" 
This reverts commit a2c309a2b0.

The above commit is causing crashes on the stm32f103xb chip when spi
is in use.  It's unclear what the cause of the regression is, but the
optimization isn't required so revert it until the root cause can be
determined.

Kevin O'Connor 98c7c7603e basecmd: No need for finalize_config command to send "config" response 
The host code always issues a get_config command immediately after
finalize_config, so there is no need to send the two config response
messages.

Arne Jansen a2c309a2b0 stm32: performance improvement for spi on stm32f0 
The stm32 has a small queue for spi tx/rx. The current code only uses the
spi with a single byte buffer, effectively waiting for each byte to complete
before starting the next transfer.
This patch changes the structure of spi_transfer() to make use of the queue
and achieve back-to-back transfer of bytes on spi.

Arne Jansen ce35ee45d6 stm32: fix spi_transfer for stm32f0 
The current code accesses the DR as 32 bit. This enabled data packing mode,
effectively adding a 00 byte between each sent byte. The receive side had
similar problems.
To prevent this, all accesses are 8 bit now, even though this is not
necessary on stmf[14].
