+What:           /sys/devices/platform/at91_can/net/<iface>/mb0_id
+Date:           January 2011
+KernelVersion:  2.6.38
+Contact:        Marc Kleine-Budde <kernel@pengutronix.de>
+Description:
+                Value representing the can_id of mailbox 0.
+
+                Default: 0x7ff (standard frame)
+
+                Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
+                "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
+                contents of mailbox 0 may be send under certain
+                conditions (even if disabled or in rx mode).
+
+                The workaround in the errata suggests not to use the
+                mailbox and load it with an unused identifier.
+
+                In order to use an extended can_id add the
+                CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
+
+                - standard id 0x7ff:
+                echo 0x7ff      > /sys/class/net/can0/mb0_id
+
+                - extended id 0x1fffffff:
+                echo 0x9fffffff > /sys/class/net/can0/mb0_id

+ROM-able zImage boot from MMC
+-----------------------------
+
+An ROM-able zImage compiled with ZBOOT_ROM_MMCIF may be written to MMC and
+SuperH Mobile ARM will to boot directly from the MMCIF hardware block.
+
+This is achieved by the mask ROM loading the first portion of the image into
+MERAM and then jumping to it. This portion contains loader code which
+copies the entire image to SDRAM and jumps to it. From there the zImage
+boot code proceeds as normal, uncompressing the image into its final
+location and then jumping to it.
+
+This code has been tested on an AP4EB board using the developer 1A eMMC
+boot mode which is configured using the following jumper settings.
+The board used for testing required a patched mask ROM in order for
+this mode to function.

+    | | | | |x| |x on
+
+The zImage must be written to the MMC card at sector 1 (512 bytes) in
+vrl4 format. A utility vrl4 is supplied to accomplish this.
+
+e.g.
+        vrl4 < zImage | dd of=/dev/sdX bs=512 seek=1
+
+A dual-voltage MMC 4.0 card was used for testing.
