Subject: bootm: set max decompression size for LZO
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=77cc8902e98f4b4a36688f454a07ad7bc82793a2;p=project%2Fbcm63xx%2Fu-boot.git

bootm: set max decompression size for LZO

The LZO decompressor wasn't initializing the maximum output size, which
meant it would fail to decompress most of the time.
