From 8f11447daf2efab972fc3adf6ba32cabc2ab3882 Mon Sep 17 00:00:00 2001 From: Cedric Roux Date: Fri, 7 Sep 2018 23:54:46 +0200 Subject: [PATCH] ARM: s3c24xx: Correct SD card write protect detection on Mini2440 The mini2440 computer uses "active high" to signal that the "write protect" of the inserted MMC is set. The current code uses the opposite, leading to a wrong detection of write protection. The solution is simply to use ".wprotect_invert = 1" in the description of the MMC.
