load address and entry point address do NOT depend on which image you use for building the U-Boot image (actually the only choice you have is using the raw binary or the compressed raw binary). They depen on your kernel's memory map, and nothing else.
I noticed that the load address and entry point are all set to ${ZRELADDR} in both arch/armnommu/boot/Makefile and arch/arm/boot/Makefile. In my case (CM946E and Integrator CP) the memory map is as follows.
0x00000000 --- Flash (alias) 0x00100000 --- SDRAM (128M) 0x10000000 --- CM control registers 0x24000000 --- Flash (16M)
At reset the top 256K (0x24FC0000 - 0x24FFFFFF) of flash is mapped to address 0x0.
So ${ZRELADDR} should be set to 0x00180000, right? Thus the load address and entry point are both set to 0x00180000. Right?
Sorry for some typo. I mean {ZRELADDR} should be set to 0x00108000. {ZRELADDR} always ends with 0x8000 for ARM.
