Subject: apm821xx: Migrate to libdeflate
X-Git-Tag: v23.05.0-rc1~668
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4ca858f1a082414bf7ace719c1b61ae54fd8e015;p=openwrt%2Fopenwrt.git

apm821xx: Migrate to libdeflate

libdeflate's gzip compressor provides a better
compression ratio and uboot's decompressor has
no problem with the data streams.

Tested on MX60, WNDR4700, WNDAP660
