+
+This CPU card is based on an i.MX23 CPU. The card is shipped with:
+
+- 64 MiB synchronous dynamic RAM (mobile DDR type)
+
+
+Memory layout when @b barebox is running:
+
+- 0x40000000 start of SDRAM
+- 0x40000100 start of kernel's boot parameters
+  - below malloc area: stack area
+  - below barebox: malloc area
+- 0x42000000 start of @b barebox
+
+@section get_imx23_olinuxino_binary How to get the bootloader binary image:
+
+Using the default configuration:
+
+@verbatim
+make ARCH=arm imx23_olinuxino_defconfig
+@endverbatim
+
+Build the bootloader binary image:
+
+@verbatim
+make ARCH=arm CROSS_COMPILE=armv5compiler
+@endverbatim
+
+@note replace the armv5compiler with your ARM v5 cross compiler.
+
+@section imx233-olinuxino How to prepare an MCI card to boot
+the imx233-olinuxino with barebox
+
+- Create four primary partitions on the MCI card
+ - the first one for the bootlets (about 256 kiB)
+ - the second one for the persistant environment
+   (size is up to you, at least 256k)
+ - the third one for the kernel (2 MiB ... 4 MiB in size)
+ - the 4th one for the root filesystem which can fill the
+   rest of the available space
+
+- Mark the first partition with the partition ID "53" and copy the bootlets
+  into this partition (currently not part of @b barebox!).
+
+- @b barebox expect device tree blob file imx23-olinuxino.dtb
+  into directory env/oftree. At compile time, copy blob file into directory
+  arch/arm/boards/imx233-olinuxino/env/oftree/.
+
+- Copy the default @b barebox environment into the second partition
+  (no filesystem required).
+
+- Copy the kernel into the third partition (no filesystem required).
+
+- Create the root filesystem in the 4th partition. You may copy an
+  image into this partition or you can do it in the classic way:
+  mkfs on it, mount it and copy all required data and programs into it.
