Subject: [PATCH] ARC: [build] Support gz, lzma compressed uImage
Date: Tue, 4 Oct 2016 16:34:27 -0700 [thread overview]
Message-ID: <1475624067-17290-1-git-send-email-danielmentz@google.com> (raw)
Add support for lzma compressed uImage.
Support for gzip was already available but could not be enabled because
we were missing CONFIG_HAVE_KERNEL_GZIP in arch/arc/Kconfig.
