This is v10 of the patchset adding support Odroud XU3 board.

link to the previous version:
v2: https://www.mail-archive.com/u-boot at lists.denx.de/msg152275.html
v3: https://www.mail-archive.com/u-boot%40lists.denx.de/msg152677.html
v4: https://patchwork.ozlabs.org/patch/407411/
v5: https://patchwork.ozlabs.org/patch/407941/
v6: https://patchwork.ozlabs.org/patch/408647/
v7: https://patchwork.ozlabs.org/patch/410204/
v8: https://patchwork.ozlabs.org/patch/410709/
v9: https://patchwork.ozlabs.org/patch/415514/

The patchset by Akshay Saraswat is already merged into u-boot-samsung. Please ignore the instruction about the additional patchset in v8.

How to test this patch:
1. git clone http://git.denx.de/u-boot-samsung.git
2. Apply this patchset
3. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- odroid-xu3_config
4. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j8
5. Now you can use u-boot-dtb.bin for your downloading

WARNING: (update in V10)
It was impossible to make the u-boot image smaller than 335872 bytes, and also
I did not want to waste my time to make it fit for that restriction, because
the discussion about this issue is in progress in malining list. I used BL2 by
Suriyan Ramasami <[email protected]> which the restriction is removed for
testing. If you need the BL2 for testing, please contact me or Suriyan.

Note: If you use micro SD card for your test you have to apply the below patch additionally. This patch is needed, because micro sd card is recognized as MMC1 instead of MMC0. Additional work is needed to make it work regardless of device id.

Thanks for Sjoerd Simons. Not only did he comment my patchset, but he also made
real patch for me. I squashed some part of that patchset, and included the remainings into my patchset.

Changes for v2:
- Add a patch to add new common setup header file for Odroid X2/U3 and Odroid XU3

Changes for v3:
- Remove the patch which adds new common setup header file from v2
- Remove the wrong patch to fix GPIO information of Exynos 5800
- Remove unnecessary node from DT file
- Remove unnecessary features from config file
- Fix some trivial typos in comments

Changes for v4:
- Add MMC FIFO buffer's configuration to DT file
- Make CONFIG_OF_CONTROL be set by the target information
- Add basic document to doc/README.odroid-xu3
- Add CONFIG_CMD_EXT4 to config file
- Add environment size and offset to config file
- Add extra default environment to make bootable without modification
- Remove unnecessary features from config file

Changes for v5:
- Add the specific build instruction
- Update the information of patchset by Akshay Saraswat
- Convert /include/ to #include in DT file

Changes for v6:
- Separate out the documentation to new commit
- Remove unnecessary header file inclusuib from the board-specific setup file
- Make the function board_clock_init be declared, only when CONFIG_BOARD_EARLY_INIT_F is defined

Changes for v7:
- Fix several errata in the documentation
- Remove OF_CONTROL dependency from !SPL_BUILD

Changes for v8:
- Remove unnecessary properties in DT mmc node

Changes for v9:
- Remove the first patch which change GPIO entries order. It became useless,
after DT support is added
- Remove useless variables in the default environment
- Add the new contents to the documentation of Odroid X2/U2, instead of making new document for Odorid XU3
- Remove the detailed information in the header file, and leave the reference to the documentation

Changes for v10:
- Move the non common configs in Exynos5420 config file to each board file
- Remove the config unsets which are added to make the result image small This is needless now, because the image is not small enough even though
these
unsets are added.
- Remove redundant DT node and properties
- Remove the odroid-xu3 board file and make odroid-xu3 a variant of smdk5420
- Fix some errata in documentation
- Include the patch by Sjoerd Simons as 4th patch

I talked to man from the hardkernel, and he said that there is no restrictions about adding BL1/BL2/TZSW as a binary blob to the Mainline U-Boot. So I think, in this case it should be provided also with those patches. Then we have a complete board setup.

To Hyungwon,
There is a size limit for each patch (100KiB), so if you would like to add such binary blob, you should add it using this site:
http://www.denx.de/wiki/attach/U-Boot/TooBigPatches
after a registration.

I do have a signed BL2 (1MB U-Boot image - same as for the Odroid U3) at http://forum.odroid.com/viewtopic.php?f=98&t=7388
It has the full package - BL1/BL2/TZ and the sd_fusing script which works for both SD as well as eMMC.
If we go with this BL2, then CONFIG_ENV_OFFSET (currently set at 1280
* 1024) will clash with the TZ area in SD card. ( I am assuming its OK for eMMC as the ENV resides in the user partition and not in boot0) This offset is OK for the Odroid-U3 as the TZ is smaller (156 K). For the Odroid U3: free area is after 2111 + (156 * 2) = 2423. The ENV starts at 1280K = offset block 2560.
For the Odroid-XU3 the TZ is 256K. Free area after the blobs starts from 2111 + (256 * 2) = 2623.
Hence, we will have to shift CONFIG_ENV_OFFSET to anything greater than 2623 (512 byte) blocks. Anything with CONFIG_ENV_OFFSET (SZ_1K * 1312) should work.

Thanks and Regards
