Beaglebone Black and libgles-omap3 : build problem

[Carlos Rafael Giani <dv@pseudoterminal.org>]

Hello,

I have a BeagleBone black here, and want to build a rootfs for it with 
Yocto. It shall include support for the SGX GPU.

But when I try to build this, I get:

ERROR: Nothing PROVIDES 'libgles-omap3'
ERROR: libgles-omap3 was skipped: incompatible with machine beaglebone 
(not in COMPATIBLE_MACHINE)
ERROR: libgles-omap3 was skipped: incompatible with machine beaglebone 
(not in COMPATIBLE_MACHINE)
ERROR: libgles-omap3-x11 PROVIDES libgles-omap3 but was skipped: 
incompatible with machine beaglebone (not in COMPATIBLE_MACHINE)
ERROR: libgles-omap3 was skipped: incompatible with machine beaglebone 
(not in COMPATIBLE_MACHINE)

However, this is incorrect. The BeagleBone Black has an AM3359 SoC, 
which does have the SGX, so it is compatible. Looking into the recipe, 
it lists ti33x as being compatible, yet the build breaks. I fixed this 
locally by adding "beaglebone" to the list of compatible machines, but 
of course this is a hack.

Does anybody have some insight into this? Is "beaglebone" perhaps the 
wrong machine for the BeagleBone black? I didn't find any machine config 
called "bblack" or "beagleboneblack" or similar.

cheers
