Ok, that means you are using normal U-Boot (CFG_PCI_BOOT not defined) and that may be causing the ‘if’ part being executed even on unmodified board since U-Boot sets (forces) PINMUX to EMIFA mode.
Can you comment out that (PINMUX0 setting) part in U-Boot and try?

The reason is, when the (unmodified) EVM is put into PCI slot, the on-board logic automatically enables PCI (EMIF disabled). Can you clarify how are you loading U-Boot and kernel images?
