        The UBports docs describes the process of finding the offset base of boot.img really briefly, and its not very helpful. Is there a script to find it? or where to search for the "devices that share the same SoC" base offset's?

          i believe i found the answer: config PHYS_OFFSET in my device kernel code.
          [kernel code dir]/arch/arm/Kconfig:

          config PHYS_OFFSET
                  hex "Physical address of main memory" if MMU
                  depends on !ARM_PATCH_PHYS_VIRT
                  default DRAM_BASE if !MMU
                  default 0x00000000 if ARCH_EBSA110 || \
                                  ARCH_FOOTBRIDGE || \
                                  ARCH_INTEGRATOR || \
                                  ARCH_IOP13XX || \
                                  ARCH_KS8695 || \
                                  ARCH_REALVIEW
                  default 0x10000000 if ARCH_OMAP1 || ARCH_RPC
                  default 0x20000000 if ARCH_S5PV210
                  default 0xc0000000 if ARCH_SA1100
                  help
                    Please provide the physical address corresponding to the
                    location of main memory in your system.
