Subject: [PATCH v2 1/5] arm: decompressor: set malloc pool size for the decompressor
Date: Tue,  2 Jun 2020 18:17:27 +0200	[thread overview]
Message-ID: <20200602161731.23033-2-l.stelmach@samsung.com> (raw)
In-Reply-To: <20200602161731.23033-1-l.stelmach@samsung.com>

Move the definition of malloc pool size of the decompressor to
a single place. This value will be exposed later for kexec_file loader.
