[meta-freescale] Status of i.MX8 support

[Teemu K]

Hi,

Interesting since linux-fslc-imx doesn't list mx8 as
'compatible_machine', but linux-imx does.

When setting preferred provider for virtual/kernel to linux-fslc-imx I
got this error:
"ERROR: Nothing PROVIDES 'virtual/kernel'
linux-imx PROVIDES virtual/kernel but was skipped:
PREFERRED_PROVIDER_virtual/kernel set to linux-fslc-imx, not
linux-imx"

So something is wrong/missing there.

But I was able to compile image for i.MX8 once I started using rpm
instead deb. Next thing is that do I get the board booting from that
image.
