DTB for BBB?

[Shiro]

Hello,

I’m new to RTEMS (but not new to embedded RTOS deployment).  I worked through the BBB QuickStart and have run hello.exe on a BBB.

Question regarding the correct DTS for BBB:  in section 8.2.3.2 of the online docs: 
	https://docs.rtems.org/branches/master/user/bsps/bsps-arm.html?highlight=dts#beagle

I don't follow this:

We build the dtb from the FreeBSD source matching the commit hash from the libbsd HEAD of freebsd-org.  For example if the HEAD is at “19a6ceb89dbacf74697d493e48c388767126d418” …

Can anyone point me to where HEAD is determined?  And how it matched into the FreeBSD.org <http://freebsd.org/> tree?


Best regards,
-david
