The Boot ROM supports authentication feature to prevent malformed software from being run on products. The signature is added at the tail of the second stage loader (= SPL in U-boot terminology). The size of the second stage loader was 64KB, and it was consistent across SoCs. The situation changed when LD20 SoC appeared; it loads 80KB second stage loader, and it is the only exception. Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is loaded from the 64KB offset of non-volatile devices. This means the signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot proper image. Let's move the U-Boot proper image to 128KB offset. It uses 48KB for nothing but padding, and we could actually locate the U-Boot proper at 80KB offset. However, the power of 2 generally seems a better choice for the offset address.
