mpc83xx: Add support for MPC83xx PCI-E controllers

2009-01-22T00:43:49+00:00

This patch adds support for MPC83xx PCI-E controllers in Root Complex
mode.

The patch is based on Tony Li and Dave Liu work[1].

Though unlike the original patch, by default we don't register PCI-E
buses for use in U-Boot, we only configure the controllers for future
use in other OSes (Linux). This is done because we don't have enough
of spare BATs to map all the PCI-E regions.

To actually use PCI-E in U-Boot, users should explicitly define
CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And
only then U-Boot will able to access PCI-E, but at the cost of disabled
address translation.

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.

Allow console input to be disabled

2008-09-06T20:36:54+00:00

Added new CONFIG_DISABLE_CONSOLE define and GD_FLG_DISABLE_CONSOLE.

When CONFIG_DISABLE_CONSOLE is defined, setting
GD_FLG_DISABLE_CONSOLE disables all console input and output.

mpc83xx: Store and display Arbiter Event Register values

2008-09-03T21:06:57+00:00

Record the Arbiter Event Register values and optionally display them.

The Arbiter Event Register can record the type and effective address of
an arbiter error, even through an HRESET. This patch stores the values in
the global data structure.

Display of the Arbiter Event registers immediately after the RSR value
can be enabled with defines. The Arbiter values will only be displayed
if an arbiter event has occured since the last Power On Reset, and either
of the following defines exist:
 #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and
                                    and type register values
 #define CONFIG_DISPLAY_AER_FULL  - display and interpret the arbiter
                                    event register values

Address Only transactions are one of the trapped events that can register
as an arbiter event. They occur with some cache manipulation instructions
if the HID0_ABE (Address Broadcast Enable) is set and the memory region
has the MEMORY_COHERENCE WIMG bit set. Setting:
 #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address
                              only events, so that it can still capture
                              other real problems.

Change bd/gd memsize/ram_size to be phys_size_t.

2008-06-11T22:54:53+00:00

Currently, both are defined as an unsigned long, but
should be phys_size_t. This should result in no real change,
since phys_size_t is currently an unsigned long for all the
default configs.  Also add print_lnum to cmd_bdinfo to deal
with the potentially wider memsize.

FSL LAW: Keep track of LAW allocations

2008-06-11T06:50:53+00:00

Make it so we keep track of which LAWs have allocated and provide
a function (set_next_law) which can allocate a LAW for us if one is
free.

In the future we will move to doing more "dynamic" LAW allocation
since the majority of users dont really care about what LAW number
they are at.

Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them

POST: replace the LOGBUFF_INITIALIZED flag in gd->post_log_word (1 << 31) with the GD_FLG_LOGINIT flag in gd->flags.

2008-05-20T21:24:38+00:00

This way we become able to utilize the full post_log_word for POST
activities (overwise, POST ECC, which has 0x8000 ID, could be
erroneously treated as started in post_output_backlog() even if there
was actually no POST ECC run (because of OCM POST failure, for
example).
