Split hardware access, OS abstraction and chip drivers out of flash.h to<br>
get a better overview of what belongs where.<br>
<br>
This patch is only the first step, but it hopefully will make working<br>
with the code and especially porting to new platforms easier.<br>
<br>
Subsequent patches should move #includes for the newly created files<br>
hwaccess.h and chipdrivers.h from flash.h to the files which need them.<br>
Programmers should live in a separate header file as well, but that<br>
would have made this patch pretty difficult to read.<br>
<br>

that platform a patch for Makefile is needed. I have attached that patch.<br>
