Simple change those two places to, say, 40800000 by editing bootcmd. (Not knowing your system, I presume RAM starts at 4000,0000 and 4080,0000 then would be 8MiB after the beginning. U-Boot will copy the kernel to 4008000 so the kernel should not be bigger than 7.5MiB but the other snippets from your log say the kernel is ~3.2MiB, so this should be fine.
