[U-Boot] Detecting U-boot in linux kernel startup

[U-Boot] Detecting U-boot in linux kernel startup

[Kristoffer Ericson]

Greetings,

Im in the situation where most of the hp jornada 700-series handhelds
got a rom containing wince while mine (and shortly alot more) contain uboot.
So instead of adding alot of #ifdefs inside the kernel, I thought that I could
do a check at bootup instead. I basicly need some unique id that only the flashrom
would contain (e.g "u-boot ..blabla).

So, any good location/string to check to confirm that its infact u-boot on the
rom and not wince?

Best wishes
Kristoffer

Why not just add a unique marker to the kernel's command line when
booting from U-Boot?
