From 645c48f50eab307a9879a82c4d066e74114ec78a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20Kochma=C5=84ski?= Date: Fri, 29 May 2015 16:55:41 +0200 Subject: sunxi: Create helper function veryfing valid boot signature on MMC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch extracts checking for valid SD card "eGON.BT0" signature from `board_mmc_init` into function `sunxi_mmc_has_egon_boot_signature`. Buffer for mmc sector is allocated and freed at runtime. `panic` is triggered on malloc failure.
