Subject: [PATCH v2 10/15] media: s5p-mfc: Reduce firmware buffer size for MFC v6+ variants
Date: Mon, 20 Feb 2017 14:38:59 +0100 [thread overview]
Message-ID: <1487597944-2000-11-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1487597944-2000-1-git-send-email-m.szyprowski@samsung.com>
Firmware for MFC v6+ variants is not larger than 400 KiB, so there is no
need to allocate a full 1 MiB buffer for it. Reduce it to 512 KiB to keep
proper alignment of allocated buffer.
