Add support for Synology DS414 and some related fixes

This patch series ultimately adds support for Synology DS414 NAS after a few fixes:
* Patches 1-3 and 5 fix various files for enabled debugging.
* Patch 4 updates the board porting guide in README file.
* Patches 6-8 hold crucial fixes necessary for DS414 support.
* Patches 9 and 10 contain the actual board support, split into a generic part for MV78230 SoC and a board specific part for clarity.
* Patch 11 adds a new command to deal with Synology specialties.

In case you would like me to split this into multiple series, just let me know and I will resend.

Hi Phil,

(added Luka to Cc)

Very nice to see other Armada XP based boards getting supported in mainline U-Boot. I'm currently also working on a new XP board based on the MV78260. And stumbled over a few of the problems you have met in your Armada XP support as well.

Since I'm currently preparing a new patchset for all this, including the full DM SPL support as well, perhaps it would be best, if you base your MV78230 work in top of my new patches. I will send the new patches to the list later today. And will also publish a git branch for easier work with it. Since there are some dependencies with other patches as well.

BTW: With this work you should be able to drop all those "non-DM" patches from your series.

Thanks,
Stefan

PS: Please keep Luka and me on Cc on all mvebu related patches.

Hi Stefan,

Sounds very good, I'm looking forward to seeing how you solved things and how that combines with my stuff.

Nice!

Will do.

Thanks, Phil

Hi Phil,

(added Dennis, as he is also interested in this new git branch)

Thanks.

Okay. I've sent the new patches to the list. And also added a branch to the "u-boot-a38x.git" gitlab repository. You can find a full working version in this branch now "mvebu-dm-spl-2015-12-14":

https://gitlab.denx.de/sr/u-boot-a38x/commits/mvebu-dm-spl-2015-12-14

Please base your work on top of this branch if possible. Adding support for your MV78230 should be quite straight forward now.

Just let me know if you have any questions.

@ Dennis:
This branch also includes the latest version for the ClearFog. Please take a look at it and let me know if it works for you.

Thanks,
Stefan

Hi Stefan,

After skimming through your patches, I'm quite convinced it will be.

Thanks, Phil

Hi Phil,

One thing to note: Please make sure to add the "u-boot,dm-pre-reloc;" properties to the device-tree nodes that are used in the SPL. So especially the UART and perhaps the SPI NOR (not sure your board boots from this device) need these properties. And also, please check that you have the defconfig from the new branch as a a basis for your board port.

Thanks,
Stefan
