lib/zlib: sparse fixes

define Z_NULL to (void *)0 include/u-boot/zlib.h to get rid of most of
the NULL pointer warnings.

lib: zlib: remove the limitation for cannot using 0 as start

2012-09-29T14:26:08+00:00

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.

lib: zlib: include deflate into zlib build

2012-09-29T14:26:08+00:00

Add a new config CONFIG_GZIP_ENABLED, if enabled, the uboot bin would
include zlib's deflate method which could be used for compressing.

zlib: handle overflow while calculating available stream input size

2011-10-17T19:45:35+00:00

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.
