Unable to calculate the addresses myself, I found in U-boot 
already stated address variables of Linux kernel /boot/uImage and 
ramdisk /uInitrd to be respecively addr_kern=0x680000, and 
addr_rd=0x1100000, which is an offset of 5568KiB.

As stated earlier, it is possible to load kernel.bin from address 
0x600000, perhaps 0x680000 is just enough. Will try this, 
reporting back in some hours.
