Naively this sounds a little odd; the value here is in a CPU register 
all the time, not in memory, so I'm not sure why endianness is relevant? 
Presumably the CPU doesn't end up byte-swapping values in registers when 
running in BE mode or it takes an SMC? If it does, why don't we need 
cpu_to_le32(TF_SET_CPU_BOOT_ADDR_SMC) too?

Sorry if this is a silly question; I haven't followed any of the BE 
kernel patches.
