[Linux-mips-commits]CVS: linux/arch/mips/zboot/lib Makefile,NONE,1.1 zlib.c,NONE,1.1

[Pete P. <pp...@us...>]

Update of /cvsroot/linux-mips/linux/arch/mips/zboot/lib
In directory usw-pr-cvs1:/tmp/cvs-serv26774/arch/mips/zboot/lib

Added Files:
	Makefile zlib.c 
Log Message:
Alchemy PB1000 zImage support. 

Most of this work is portable to other embedded mips boards. The board
specific code is in the pb1000 directory and it's just head.S and the 
Makefile and linker script.

The common code was ported with very few modifications from the PPC 
boot code.


--- NEW FILE: Makefile ---
#
# Makefile for some libs needed by zImage.

L_TARGET := zlib.a

obj-y := zlib.o

include $(TOPDIR)/Rules.make

--- NEW FILE: zlib.c ---
/*
 * This file is derived from various .h and .c files from the zlib-0.95
 * distribution by Jean-loup Gailly and Mark Adler, with some additions
 * by Paul Mackerras to aid in implementing Deflate compression and
 * decompression for PPP packets.  See zlib.h for conditions of
 * distribution and use.
 *
 * Changes that have been made include:
 * - changed functions not used outside this file to "local"
 * - added minCompression parameter to deflateInit2
 * - added Z_PACKET_FLUSH (see zlib.h for details)
 * - added inflateIncomp
