There are huge differences between architectures.  While  on  PowerPC
you  usually  have  flash  at  some  high addresses and RAM mapped at
0x0000, you will see flash at 0x0000 and RAM  at  high  addresses  on
ARM.

You really guessed wrong here.

... which is OK for PowerPC, but seriously broken for all ARM systems
I know.

You have to know the memory map of your system, and you  have  to  be
aware  wat  the  load address (-a option to mkimage), entry point (-e
option) and the address "addr" where your image is stored in RAM when
you type "bootm addr" mean.
