Subject: [RFC 2/3] arm64 linux loader: use grub_efi_find_config_table to find DT
Date: Tue,  1 Mar 2016 17:41:42 +0000	[thread overview]
Message-ID: <1456854103-12095-3-git-send-email-leif.lindholm@linaro.org> (raw)
In-Reply-To: <1456854103-12095-1-git-send-email-leif.lindholm@linaro.org>

Use new helper function rather than manually iterating through system
table.
