Yes, it is, although the support (more precisely, the host side) was
added recently (and thus it's not yet on RTEMS' libbsd). These are the
files used by the Beaglebone Black:

http://svnweb.freebsd.org/base/head/sys/arm/ti/am335x/am335x_musb.c?revision=283276&view=markup
This makes it much easier.
Is there an easy way to port these to RTEMS? I'm not sure how much the
BSD driver infrastructure has changed since 8.2.
It is actually FreeBSD 9.3, but I don't know how the USB stack evolved.

Which USB and MMC/SD card hardware modules has this chip? Are they
standard modules, e.g. EHCI, SDHC or something like this?
From what I saw, the USB module on the Beaglebone Black is built
around the Mentor musbmhdrc USB OTG controller, which is not EHCI or
OHCI compliant. The MMC/SD module is mostly compliant with SDHCI, with
a few quirks.
Is this Mentor USB stuff supported by FreeBSD? Writing a new USB host/OTG
driver is a major task.
