boot.axf is kind like an app of boot1, there is no asm code in boot.axf. 
Boot1 may also run different boot.axf which do other things like quality 
check or massive production. Usually boot.axf loads different OS loader. 
For booting linux, boot.axf just loads the kernel and jumps to the 
kernel entry before. But now we have u-boot, boot.axf loads u-boot, 
u-boot loads kernel...
