+ U-boot for Odroid X2/U3
+========================
+
+1. Summary
+==========
+This is a quick instruction for setup Odroid boards based on Exynos4412.
+Board config: odroid_config
+
+2. Supported devices
+====================
+This U-BOOT config can be used on two boards:
+- Odroid U3
+- Odroid X2
+with CPU Exynos 4412 rev 2.0 and 2GB of RAM
+
+3. Boot sequence
+================
+iROM->BL1->(BL2 + TrustZone)->U-BOOT
+
+This version of U-BOOT doesn't implement SPL but it is required(BL2)
+and can be found in "boot.tar.gz" from here:
+http://dev.odroid.com/projects/4412boot/wiki/FrontPage?action=download&value=boot.tar.gz
+
+4. Boot media layout
+====================
+The table below shows SD/eMMC cards layout for U-boot.
+The block offset is starting from 0 and the block size is 512B.
+ -------------------------------------
+| Binary | Block offset| part type |
+| name | SD | eMMC |(eMMC only)|
+ -------------------------------------
+| Bl1 | 1 | 0 | 1 (boot) |
+| Bl2 | 31 | 30 | 1 (boot) |
+| U-boot | 63 | 62 | 1 (boot) |
+| Tzsw | 2111 | 2110 | 1 (boot) |
+| Uboot Env | 2500 | 2500 | 0 (user) |
+ -------------------------------------
+
+5. Prepare the SD boot card - with SD card reader
+=================================================
+To prepare bootable media you need boot binaries provided by hardkernel.
+File "boot.tar.gz" (link in point 3.) contains:
+- E4412_S.bl1.HardKernel.bin
+- E4412_S.tzsw.signed.bin
+- bl2.signed.bin
+- sd_fusing.sh
+- u-boot.bin
+
+This is all you need to boot this board. But if you want to use your custom
+u-boot then you need to change u-boot.bin with your own u-boot binary*
+and run the script "sd_fusing.sh" - this script is valid only for SD card.
+
+*note:
+The proper binary file of current U-boot is u-boot-dtb.bin.
+
+quick steps for Linux:
+- extract boot.tar.gz
+- put any SD card into the SD reader
+- check the device with "dmesg"
+- run ./sd_fusing.sh /dev/sdX - where X is SD card device (but not a partition)
+Check if Hardkernel U-boot is booting, and next do the same with your U-boot.
+
+6. Prepare the eMMC boot card
+ with a eMMC card reader (boot from eMMC card slot)
+=====================================================
+To boot the device from the eMMC slot you should use a special card reader
+which supports eMMC partiion switch. All of the boot binaries are stored
+on the eMMC boot partition which is normally hidden.
+
+The "sd_fusing.sh" script can be used after updating offsets of binaries
+according to the table from point 4. Be sure that you are working on the right
+eMMC partition - its size is usually very small, about 1-4 MiB.
+
+7. Prepare the eMMC boot card
+ with a SD card reader (boot from SD card slot)
+=================================================
+If you have an eMMC->microSD adapter you can prepare the card as in point 5.
+But then the device can boot only from the SD card slot.
+
+8. Prepare the boot media using Hardkernel U-boot
+=================================================
+You can update the U-boot to the custom one if you have an working bootloader
+delivered with the board on a eMMC/SD card. Then follow the steps:
+- install the android fastboot tool
+- connect a micro usb cable to the board
+- on the U-boot prompt, run command: fastboot (as a root)
+- on the host, run command: "fastboot flash bootloader u-boot-dtb.bin"
+- the custom U-boot should start after the board resets.
+
+9. Partition layout
+====================
+Default U-boot environment is setup for fixed partiion layout.
+
+Partition table: MSDOS. Disk layout and files as listed in the table below.
+ ----- ------ ------ ------ -------- ---------------------------------
+| Num | Name | FS | Size | Offset | Reguired files |
+| | | Type | MiB | MiB | |
+ ----- ------ ------ ------ -------- ---------------------------------
+| 1 | BOOT | fat | 100 | 2 | uImage, exynos4412-odroid**.dtb |
+| 2 | ROOT | ext4 | 3072 | | any Linux system |
+| 3 | DATA | any | 3072 | | |
+| 4 | UMS | any | any | | |
+ ----- ------ ------ ------ -------- ---------------------------------
+
+**note:
+Supported fdt files are:
+- exynos4412-odroidx2.dtb
+- exynos4412-odroidu3.dtb
+
+The environment variable "dfu_alt_info" is setup for above layout.
+Each partition size is just an example, dfu_alt_info tries init
+four partitions - size is not so important.
+
+10. The environment and booting the kernel
+==========================================
+There are four macros defined in config for various boot options:
+for kernel with device tree support:
+- mmcbootu_fdt - (default) load proper dtb and uImage
+- mmcbootz_fdt - load proper dtb and zImage
+for kernel without device tree support:
+- mmcbootu_nofdt - load uImage
+- mmcbootz_nofdt - load zImage
