eaaebf3291 stmhal: Initialise stack pointer correctly. 
Stack is full descending and must be 8-byte aligned.  It must start off
pointing to just above the last byte of RAM.

Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
and so was not 8-byte aligned.  This caused a bug in combination with
alloca.

This patch also updates some debug printing code.

Addresses issue #872 (among many other undiscovered issues).

3688414d9d Put some code into the first 16K of flash 
This basically shrinks the remaining size of flash in the portion
that goes after the internal flash drive.

dd38d90724 Initial checkin with STM HAL 
This compiles and links, but hasn't been tested on a board
yet and even if it was run, it doesn't currently do anything.
