x86: ivybridge: Do the SATA init before relocation The SATA device needs to set itself up so that it appears correctly on the PCI bus. The easiest way to do this is to set it up to probe before relocation. This can do the early setup. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

x86: ivybridge: Do the SATA init before relocation The SATA device needs to set itself up so that it appears correctly on the PCI bus. The easiest way to do this is to set it up to probe before relocation. This can do the early setup. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

x86: Add a x86_ prefix to the x86-specific PCI functions These functions currently use a generic name, but they are for x86 only. This may introduce confusion and prevents U-Boot from using these names more widely. In fact it should be possible to remove these at some point and use generic functions, but for now, rename them.
