I did see other platforms generates PBL images with RCW and PBI built-in. However, this is always with CONFIG_RAMBOOT_PBL set (SPI, NAND or SD-CARD boot). This is the memory map described in the t104xrdb/README file: NOR Flash memory Map --------------------- 163 Start End Definition Size 164 0xEFF40000 0xEFFFFFFF u-boot (current bank) 768KB .... 177 0xE8000000 0xE801FFFF RCW (current bank) 128KB For me, it means the RCW will not be included in the u-boot binary.
