From: Wenyou Yang Date: Sat, 8 Jun 2013 02:17:43 +0000 (+0000) Subject: ARM: at91: Change the internal SRAM memory type MT_MEMORY_NONCACHED X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=133e00116b5bc76110bcc41ded369489209b641f;p=linux-beck.git ARM: at91: Change the internal SRAM memory type MT_MEMORY_NONCACHED Because MT_DEVICE is not executable in armv7, we change the internal SRAM memory type to MT_MEMORY_NONCACHED. As it seems that caching this internal SRAM memory is not necessary, we chose the this memory type.
