cpu/mpc824x/Makefile: fix warning with parallel builds

2009-01-14T21:35:30+00:00

Parallel builds would occasionally issue this build warning:

    ln: creating symbolic link `cpu/mpc824x/bedbug_603e.c': File exists

Use "ln -sf" as quick work around for the issue.

Change DDR tlb start entry to CONFIG param for 85xx

2009-01-13T22:47:07+00:00

So that we can locate the DDR tlb start entry to the value other than 8. By
default, it is still 8.

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.

mpc86xx: Double local bus clock divider

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

The local bus clock divider should be doubled for both 8610 and 8641.

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.

85xx: Fix the boot window issue

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

If one custom board is using the 8MB flash, it is set
as FLASH_BASE = 0xef000000, TEXT_BASE = 0xef780000.
The current start.S code will be broken at switch_as.

It is because the TLB1[15] is set as 16MB page size,
EPN = TEXT_BASE & 0xff000000, RPN = 0xff000000.

For the 8MB flash case, the EPN = 0xefxxxxxx,
RPN = 0xffxxxxxx. Assume the virt address of switch_as
is 0xef7ff18c, the real address of the instruction at
switch_as should be 0xff7ff18c. the 0xff7ff18c is out
of the range of the default 8MB boot LAW window
0xff800000 - 0xffffffff.

So when we switch to AS1 address space at switch_as,
the core can't fetch the instruction at switch_as any
more. It will cause broken issue.
