Lucas,

I missed this patch when it came through.

Can you give some details about what you consider a 'safe state' for
the bootloader to bring PCI to before passing control to the kernel
(with respect to PERST#, PCI CLK, and the various host controller
registers)? I would like to investigate making PCI available in the
bootloader as well as the kernel reliable on IMX6.
