Tested flash SDB read from addresses other than 0

For this to work, I also had to add (in flash.c) setting the entry-point to the right value (the one where the SDB magic is detected). The rest of the commit files are just toying around for testing purposes. Signed-off-by: Theodor Stana <t.stana@cern.ch>
