2012-09-29lib: zlib: remove the limitation for cannot using 0 as startLei Wen
We often need the requirement that compressing those memory range start from 0, but the default deflate code in zlib prevent us to do this. Considering the special case of uboot, that it could access all memory range, it is reasonable to be able to also take the address space from 0 into compression.

2012-09-29lib: zlib: include deflate into zlib buildLei Wen
Add a new config CONFIG_GZIP_ENABLED, if enabled, the uboot bin would include zlib's deflate method which could be used for compressing. Signed-off-by: Lei Wen <leiwen@marvell.com>

2011-10-17zlib: handle overflow while calculating available stream input sizeAnatolij Gustschin
If compressed data is located in sectors at the end of the flash and it's offset + input stream size > 0xFFFFFFFF, the uncompressing time is very long, since processing of the stream is done bytewise (and not blockwise) due to overflow in inflate_fast() while calculation and checking for enough input available. Check for this overflow condition and limit the available stream input size to the actually max. possible input size. This fixes the problem. The issue is easily reproduceable by placing a gziped bitmap in flash, e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000' or 'bmp display FFF80000'. The uncompressing can take up to 3 sec. whereas it should normaly take a fraction of a second. If the 'splashimage' environment variable points to this address, the booting time also increases significantly. Signed-off-by: Anatolij Gustschin <agust@denx.de>
2011-05-12zlib: fix DEBUG buildMike Frysinger
The previous commit imported a little too much from upstream. We need to disable stdio.h when using U-Boot. Reported-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-30zlib: split up to match original source treeMike Frysinger
While looking to upgrade to zlib-1.2.5, the current mondo merge of multiple files into a single was making things way more difficult than it should have been. Hard to pick out what has been changed to port it to U-Boot, been removed as useless, and bug fixes added after the fact. So split the single file up into the original file names, and merge non-essential changes back from the original tree (for some reason, style in code in a bunch of places was changed to U-Boot style even though this isn't "U-Boot" code). The original build style is retained -- we have a single zlib.c that includes all the other files, and that is the only file we compile. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
