[U-Boot] bootflag for mpc85xx cpu?

[jin.wang]

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.
