Subject: imxtract: specify max gunzip size
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-logo.png?a=commitdiff_plain;h=05e8e2403c533cc9e7a2a548486e2e41dfd5ce53;p=u-boot.git

imxtract: specify max gunzip size

Specify max gunzip size from config to override SYS_XIMG_LEN
default value wich is 0x800000. In case we have a large portion of FIT
image, for example gzipped kernel with decompressed size large than
0x800000 we should enlarge imxract area, otherwise extracting it will
fail.

It used to be a hardcoded define in cmd/ximg.c and we are moving it to
config.
