MPC85xx: Add MPC8569 CPU support

2009-03-30T18:33:51+00:00

There is a workaround for MPC8569 CPU Errata, which needs to set Bit 13 of
LBCR in 4K bootpage. We setup a temp TLB for eLBC controller in bootpage,
then invalidate it after LBCR bit 13 is set.

85xx: Format cpu freq printing to handle 8 cores

2009-02-17T00:05:50+00:00

Only print 4 cpu freq per line.  This way when we have 8 cores its a
bit more readable.

Add secondary CPUs processor frequency for e500 core

2009-01-23T23:03:14+00:00

This patch updates e500 freqProcessor to array based on CONFIG_NUM_CPUS,
and prints each CPU's frequency separately. It also fixes up each CPU's
frequency in "clock-frequency" of fdt blob.

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.
