* misc.c
*
* This is a collection of several routines from gzip-1.0.3
* adapted for Linux.
*
* malloc by Hannu Savolainen 1993 and Matthias Urlichs 1994
*
* Modified for ARM Linux by Russell King
*
* Nicolas Pitre <nico@visuaide.com> 1999/04/14 :
* For this code to run directly from Flash, all constant variables must
* be marked with 'const' and all other variables initialized at run-time
* only. This way all non constant variables will end up in the bss segment,
* which should point to addresses in RAM and cleared to 0 on start.
* This allows for a much quicker boot time.
