has someone patched U-Boot to "support" the MPC857T?
AFAIK it's basicly a MPC855T. So the only change would be to avoid a boot message like:
CPU: unknown MPC855 (0x07000003) at 80 MHz: 4 kB I-Cache 4 kB D-Cache FEC present
All you need to do is extend the list of types defined in "cpu/mpc8xx/cpu.c" - a patch is welcome.
I'd love to present a patch. Could you please give me a pointer where to find information about the values of
k = (immr << 16) | *((ushort *) & immap->im_cpm.cp_dparam[0xB0]);
? I couldn't find some.
Is it possible to find out if it's a 855, 857 or 860 at runtime? So that we don't have to rely on DEFINES?
FAIK MPC855T and MPC857T are basicly the same. So could put both on my board without actually changing the firmware. Would be nice if u-boot could figure out which one is actually present.
Thanks,
Steven
