Subject: [PATCH 09/17] unicore32: Remove support for BZIP2 and LZMA compressed kernel
Date: Fri, 09 Nov 2018 19:02:56 +0000	[thread overview]
Message-ID: <20181109190304.8573-9-kilobyte@angband.pl> (raw)
In-Reply-To: <20181109190304.8573-1-kilobyte@angband.pl>

Made redundant by newer choices -- sort of, as no one enabled support
for XZ nor ZSTD for unicore yet...
