The boot commands - bootz/bootm mandate a third argument which is the address to the FDT blob. In cases where this argument is not specified, boot fails with a message indicating a missing FDT.
This causes non-FDT kernels to fail to boot. This patch allows both FDT and non-FDT kernels to boot by making the third parameter to the bootm/bootz optional.

Looks good, and works for my case (booting old linux-sunxi 3.4 kernels) too) :
