This commit prevents from re-configuring pins if those were configured before relocation.
Some pins - like UART or DDR must be setup before relocation (as they have 'u-boot,dm-pre-reloc' property set in DTS). Without this change, those pins are re-configured after relocation (pre_reloc_only = 0, so we do not "continue"). Such behavior may be a problem for DDR PAD configuration, as they might be already leveled/tuned with original setup).

Applied to u-boot/master, thanks!
I've bisected out to this commit and it's slightly broken things for me on an AM3352. It all works fine so long as I boot MLO from MMC (so the MMC is probed, pinctrl setup), but if I boot from UART then I get to full U-Boot, MMC hasn't been probed and the pinmuxing isn't set up for the MMC.
