BeagleBoard-X15 is the next generation Open Source Hardware
BeagleBoard based on TI's AM5728 SoC featuring dual core 1.5GHZ A15
processor. The platform features 2GB DDR3L (w/dual 32bit busses),
eSATA, 3 USB3.0 ports, integrated HDMI (1920x108@60), separate LCD
port, video In port, 4GB eMMC, uSD, Analog audio in/out, dual 1G
Ethernet.

For more information, refer to:
BeagleBoard-X15 Wiki:
http://www.elinux.org/Beagleboard:BeagleBoard-X15

AM5728 is part of the Sitara product family whose additional details
will be available: http://www.ti.com/lsds/ti/arm/overview.page

Technical Reference Manual for AM5728 is public domain at:
http://www.ti.com/lit/spruhz6

Just add basic support for the moment, the following updates are needed:
  i) Ethernet - depends on SoC dts fixes
  ii) USB Client (USB2) - depends on GPIO extcon
  ii) HDMI - additional driver fixes pending
  iii) Audio - additional driver fixes pending

1GiB ? Why would you put this here btw ? u-boot fills this one up.

Yes, it should either be the full and correct value or 0x0 (like a
number of PowerPC platforms do) so it's clear something else gives us
the right value here.

Oh neat, you put a USB3 hub on the board?

I really should cleanup and submit my patch to make the system time not
run 576ppm too fast on the AM57xx.

This will sure be a nice board when you get it released. I will have
to get one.

Honest mistake, my bad.. I thought I cleaned up the patch! Sigh!!! i
will repost with proper 2GB. it is better that way in case being used
with "other bootloaders" which are not exactly too good like u-boot.

yep - will do that similar to
https://patchwork.kernel.org/patch/5125431/ - same rationale unless
there is any specific voltage rail that you are explicitly interested
in that needs additional explanation. Is there additional rails of
interest?

yep - will do that similar to
ARM: dts: dra7-evm: Keep all VDD rails always-on - Patchwork - same rationale unless
there is any specific voltage rail that you are explicitly interested
in that needs additional explanation. Is there additional rails of
interest?

Here is what I have in mind: (updated with comments from Felipe/Tom and
above) - would you like more details added - if you could point out
areas of interest, I can help improve information provided here.
