A U-Boot image could be loaded and executed at a different location than it was linked at.
For example, Aspeed takes a stable release version of U-Boot image as the golden one for recovery purposes. When the primary storage such as flash is corrupted, the golden image would be loaded to any SRAM/DRAM address on demands through ethernet/UART/etc and run for rescue.
To deal with this condition, the PIE is needed as there is only one signed, golden image, which could be however executed at different places.
This patch adds the PIE support for ARMv7 platform.
