+Netgear ReadyNAS 2120
+This is a rack mountable 4 bay NAS using an Armada XP dual-core processor.
+UART booting
+The first UART hides behind a sticker on 4 pins.
+The machine seems to do two resets at power on which makes UART booting hard. A
+trick to work around this is::
+ scripts/kwboot -d /dev/ttyUSB0; kwboot -b images/barebox-netgear-rn2120.img -t /dev/ttyUSB0
+This way the first window in which the CPU accepts the magic string is taken by
+the first invokation which blocks until the second reset happens. The second
+window is then hit with the image to boot. This is not 100% reliable but works
+most of the time.
