Not yet.  I haven't been able to rebuild Arago using TI's instructions
on the Wiki.  I am not sure if it's a dependency issue or something
else.  When I run Linux 4.13 using Buildroot as the rootfs, it does
not appear to run da850_evm_m25p80_notify_add().  I am going to
investigate whether or not da850_evm_init() is getting called.  I was
wondering if you had some insight as to what calls that function?  It
looks like it's defined as part of MACHINE_START(DAVINCI_DA850_EVM,
"DaVinci DA850/OMAP-L138/AM18x EVM"), but I don't know how it gets
called.
