-/*
- * 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.
- *
- * Modified for Alpha, from the ARM version, by Jay Estabrook 2003.
