[U-Boot] [PATCH 1/3] mpc83xx: Add support for MPC83xx PCI-E controllers

[Liu Dave]

> This patch adds support for MPC83xx PCI-E controllers in Root Complex
> mode.
> 
> The patch is based on Tony Li and Dave Liu work[1].
> 
> Though unlike the original patch, by default we don't register PCI-E
> buses for use in U-Boot, we only configure the controllers for future
> use in other OSes (Linux). This is done because we don't have enough
> of spare BATs to map all the PCI-E regions.
> 
> To actually use PCI-E in U-Boot, users should explicitly define
> CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And
> only then U-Boot will able to access PCI-E, but at the cost 
> of disabled
> address translation.
