Now I have the U-Boot for MPC859, but I am not sure this line is correct
U-Boot 1.1.3 (Nov 11 2005 - 16:38:24)
CPU: MPC859TxxZPnnA at 133 MHz: 16 kB I-Cache 8 kB D-Cache FEC present
Looks good to me.
As far as I know, the I-Cache and the D-Cache of the MPC859 is 4 kB, as defined in the MPC866UM Appendix F.
Well, if you follow the Parametrics sheets on the freescale pages the size is not 4 KiB (= 4096 Bytes), but 4000 Bytes instead. Looks bogus to me.
We think that the MPC859 probably has phisically the same cache size as the MPC866, but only 4 kB must be used.
U-Boot uses the functions checkicache() and checkdcache() [see "cpu/mpc8xx/cpu.c"] to measure the size of the L1 instruction and data cache.
Anyway, my question is, must I worry about the data printed on the screen or can I leave as they are?
I don't see how you could change the sizes.
I mean, are these information used in other part of the U-Boot or the Kernel?
They are just informational messages.
