I've applied, but it triggers a kconfig warning (which already existed
for some other packages):

warning: (BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_NOUVEAU && BR2_PACKAGE_MESA3D_DRI_DRIVER_NOUVEAU && BR2_PACKAGE_XDRIVER_XF86_VIDEO_NOUVEAU) selects BR2_PACKAGE_LIBDRM_NOUVEAU which has unmet direct dependencies (BR2_PACKAGE_LIBDRM && (BR2_i386 || BR2_x86_64))

So it already existed for BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_NOUVEAU and
BR2_PACKAGE_MESA3D_DRI_DRIVER_NOUVEAU, and your package
(BR2_PACKAGE_XDRIVER_XF86_VIDEO_NOUVEAU) just adds a new bogus select.
I've still applied your package because this issue needs to be fixed
separately, and address for all three Config.in options.

Essentially, this happens because I'm building on ARM, and the
BR2_PACKAGE_LIBDRM_NOUVEAU option is only available on i386 and x86_64.
However, I wonder why BR2_PACKAGE_LIBDRM_NOUVEAU is not available on
ARM, since I'm pretty sure that the Nouveau driver is used on ARM on
some Tegra platforms.

Right now, this causes a build failure:

checking for LIBDRM_NOUVEAU... no
configure: error: Package requirements (libdrm_nouveau >= 2.4.25) were not met:

With the following (not very minimal) configuration:

BR2_arm=y

Can you have a look?

Thanks!
