My understanding is that a warm reset on the 8xxx CPUs isn't really a hardware reset - its just when code explicitly jumps to the warm reset entry point. For example, this board used to jump to _start_warm when "reset" was ran in U-Boot: http://git.denx.de/?p=u-boot.git;a=commitdiff;h=3792d7436e2bf881b6abdede5a481a62b5dedd55 During normal use I thought that the reset entry point was always 0xXXXXX100 and a warm reset would never occur. What is the power on reset process like on your board?
