[U-Boot] Ordering PCI device probes

[Aaron Williams <Aaron.Williams@cavium.com>]

Hi all,

I am trying to port our OcteonTX Linux NAND driver to U-Boot and am running 
into an issue with ordering. We have a bch engine which consists of a pf and a 
vf and uses SRIOV to activate the vf.

The problem is that the nand device is probed before the BCH engine is probed 
and the NAND driver depends on the BCH driver.

In Linux, this is handled by having the NAND driver probe function return 
EPROBE_DEFER which causes the probe function to be called later after all of 
the other probe functions have been called. U-Boot does not use EPROBE_DEFER 
so is there some other way I can do this or otherwise change the ordering of 
the probes?
