[U-Boot] bootflag for mpc85xx cpu?
As for mpc85xx cpu,It seems bootflag parametor in board_init_f does not work correctly,anyone ever experienced the same issue? I am using u-boot-1.3.2,No matter execute power-on or hard reset via MSR[DE],DBCR0[IDM],always get wrong bootflag value. Is there any other ways to differentiate cold reboot and warm reboot for mpc85xx series? Thanks in advance!

The boot flag is actually generally unused. I am not aware of any piece of code that actually makes any use of this variable. It is just a remainder of the historic past, i. e. of some proprietary boot software from the previous millennium.
