Subject: [AVR32] Don't reset PIO state at bootup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dde251033f3e54619317269a908ce40e6f3a8d04;p=linux-beck.git

[AVR32] Don't reset PIO state at bootup

Leave the PIO lines as the bootloader left them. This allows us to
use PIOE without disturbing the SDRAM muxing.
