mpc8[56]xx: Put localbus clock in sysinfo and gd

2008-12-20T00:32:49+00:00

Currently MPC85xx and MPC86xx boards just calculate the localbus frequency
and print it out, but don't save it.

This changes where its calculated and stored to be more consistent with the
CPU, CCB, TB, and DDR frequencies and the MPC83xx localbus clock.

The localbus frequency is added to sysinfo and calculated when sysinfo is
set up, in cpu/mpc8[56]xx/speed.c, the same as the other frequencies are.

get_clocks() copies the frequency into the global data, as the other
frequencies are, into a new field that is only enabled for MPC85xx and
MPC86xx.

checkcpu() in cpu/mpc8[56]xx/cpu.c will print out the local bus frequency
from sysinfo, like the other frequencies, instead of calculating it on the
spot.

mpc8568: Double local bus clock divider

2008-12-20T00:32:48+00:00

The clock divider for the MPC8568 local bus should be doubled, like the
other newer MPC85xx chips.

Since there are now more chips with a 2x divider than a 1x, and any new
85xx chips will probably be 2x, invert the sense of the #if so that it
lists the 1x chips instead of the 2x ones.

mpc8xxx: LCRR[CLKDIV] is sometimes five bits

2008-12-20T00:20:25+00:00

On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.

In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems.  It
should be safe as the fifth bit was defined as reserved and set to 0.

Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

85xx: Add basic e500mc core support

2008-10-24T20:10:47+00:00

Introduce CONFIG_E500MC to deal with the minor differences between
e500v2 and e500mc.

* Certain fields of HID0/1 don't exist anymore on e500mc
* Cache line size is 64-bytes on e500mc
* reset value of PIR is different
