Will do.
While we're discussing it I had 2 other questions:
1. Can anyone at Freescale give a hint about how to tell the difference
between the 8640 and 8641?
2. Does anyone know how the PVR in IBM's 750 line of processors is
parsed? I didn't see it in 750 processor datasheets and wanted to
update the following line of code in cpu/74xx_7xx.c while updating the
86xx:
- printf ("%s v%d.%d", str, (pvr >> 8) & 0xFF, pvr & 0xFF);
The 86xx and 74xx processors all use the convention below but I wanted
to make sure it wouldn't break any 750-based cpus when changing it:
- printf ("%s v%d.%d", str, (pvr >> 8) & 0xF, pvr & 0xFF);
Thanks,
Peter
