Hello tech@
I would like to add PCI devices for latest Intel SoC (Gemini Lake).
Included a patch for sdhc(4) too that depends on this to enable eMMC.
The Intel eMMC controller does not like bus power going to 0V. There
may be other systems (Apollo Lake) that need this quirk too.
With both patches I am booting from internal eMMC on HP Stream 14.
Comments? ok?
