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.

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.

mpc8[56]xx: Put localbus clock in device tree

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

Export the localbus frequency in the device tree, the same way the CPU, TB,
CCB, and various other frequencies are exported in their respective device
tree nodes.

Some localbus devices need this information to be programed correctly, so
it makes sense to export it along with the other frequencies.

Unfortunately, when someone wrote the localbus dts bindings, they didn't
bother to define what the "compatible" property should be.  So it seems no
one was quite sure what to put in their dts files.

Based on current existing dts files in the kernel source, I've used
"fsl,pq3-localbus" and "fsl,elbc" for MPC85xx, which are used by almost all
of the 85xx devices, and are looked for by the Linux code.  The eLBC is
apparently not entirely backward compatible with the pq3 LBC and so eLBC
equipped platforms like 8572 won't use pq3-localbus.

For MPC86xx, I've used "fsl,elbc" which is used by some of the 86xx systems
and is also looked for by the Linux code.  On MPC8641, I've also used
"fsl,mpc8641-localbus" as it is also commonly used in dts files, some of
which don't use "fsl,elbc" or any other acceptable name to match on.

mpc8641: Support 36-bit physical addressing

2008-11-10T16:10:05+00:00

This patch creates a memory map with all the devices
in 36-bit physical space, in addition to the 32-bit map.
The CCSR relocation is moved (again, sorry) to
allow for the physical address to be 36 bits - this
requires translation to be enabled.  With 36-bit physical
addressing enabled, we are no longer running with VA=PA
translations.  This means we have to distinguish between
the two in the config file.  The existing region name is
used to indicate the virtual address, and a _PHYS variety
is created to represent the physical address.

Large physical addressing is not enabled by default.
Set CONFIG_PHYS_64BIT in the config file to turn this on.

mpc8641: Change 32-bit memory map

2008-11-10T16:10:04+00:00

The memory map on the 8641hpcn is modified to look more like
the 85xx boards; this is a step towards a more standardized
layout going forward. As part of this change, we now relocate
the flash.

The regions for some of the mappings were far larger than they
needed to be.  I have reduced the mappings to match the
actual sizes supported by the hardware.

In addition I have removed the comments at the head
of the BAT blocks in the config file, rather than updating
them.  These get horribly out of date, and it's a simple
matter to look at the defines to see what they are set to
since everything is right here in the same file.

Documentation has been changed to reflect the new map, as this
change is user visible, and affects the OS which runs post-uboot.
