[PATCH] Kconfig for R5k/RM7k sc

[PATCH] Kconfig for R5k/RM7k sc

[Christopher G. Stach II]

    This should prevent the rm7k sc code from being built for IP32, etc.

Why do you want to do that? IMHO it's quite sensible to do a generic
O2 kernel which runs on both R5x00 and RM7000 while still using the
scache if available.

This would prevent the kernel from running on RM7k IP32 and add the
R5000 stuff to loads of machines that don't have it.  No way.

[U-Boot-Users] DB1000 Little-Endian U-Boot

[Charles Eidsness]

Hi All,

I would like to use u-boot on my DB1000 card (with an AMD Au1000 
processor) in little endian mode. After a little bit of playing around I 
have gotten it to compile, load in to the parameter FLASH and run from 
the Yamon prompt, i.e. go bec00000. But, when I switch to boot 
completely from u-boot in the parameter flash (switch S8) the card just 
hangs. Does anyone have any ideas?

Thanks,
Charles

I guess you have changed TEXT_BASE to 0xbec00000?

When you use the S8 switch, you swap the two boot flashes.

This means that the boot flash that was at 0xbec00000
now appears at 0xbfc00000.

So, you have to compile u-boot with TEXT_BASE at
0xbfc00000 to make this work.
