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].

Kevin O'Connor faeaa54925 armcm_boot: Use armcm_main() instead of main() to start board code 
The main() function has a special meaning to gcc and using it can
result in different code generation.  Use armcm_main() to avoid that.

Also, invoke SystemInit() from the board specific armcm_main() code.
This gives the board code more control over board initialization.
