8e55258f14 qe: Pass in uec_info struct through uec_initialize
The uec driver contains code to hard code configuration information for the uec
ethernet controllers. This patch creates an array of uec_info structures, which
are then parsed by the corresponding driver instance to determine configuration.
It also creates function uec_standard_init() to initialize all UEC interfaces
for 83xx and 85xx.

a89c33db96 General help message cleanup
Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

f62fb99941 Fix all linker script to handle all rodata sections
A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script.  Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.

However, '*(.rodata*)' by itself will result in sub-optimal section
ordering.  The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file.  This is easy to fix by using the
SORT_BY_ALIGNMENT command.

This patch has not be tested one most of the boards modified.  Some boards
have a linker script that looks something like this:

*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)

I change this to:

*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

The bootcounter uses 8 bytes from the muram,
because no other memory was found on this

Linux.

This feature is actual only implemented for

50a4d08e8f mpc83xx: PCI: Fix hard-coded first_busno value
We should use pci_last_busno() in pci_init_bus(), otherwise we'll
erroneously re-use PCI0's first_busno for PCI1 hoses.

NOTE: The patch is untested. All MPC83xx FSL boards I have have
PCI1 in miniPCI form, for which I don't have any cards handy.

But looking in cpu/mpc85xx/pci.c:
...
#ifdef CONFIG_MPC85XX_PCI2
        hose = &pci_hose[1];

        hose->first_busno = pci_hose[0].last_busno + 1;

And considering that we do the same for MPC83xx PCI-E support,
I think this patch is correct.

e2d72ba543 mpc83xx: PCIe: Don't start bus enumeration at 0
Currently we assign first_busno = 0 for the first PCIe hose, but this
scheme won't work if we have ordinary PCI hose already registered (its
first_busno value is 0 too).

The old code worked fine only because we have PCI disabled on
MPC837XEMDS boards in stand-alone mode (see commit 00f7bbae92
"mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards").
But on MPC837XERDB boards we have PCI and PCIe, so the bug actually
triggers.

So, to fix the issue, we should use pci_last_busno() + 1 for the
first_busno (i.e. last available busno).

fd6646c0b9 mpc83xx: Add support for MPC83xx PCI-E controllers
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.

75f35209f7 83xx: PCI agent mode fixes for multi-board systems
When running a system with 2 or more MPC8349EMDS boards in PCI agent mode,
the boards will lock up the PCI bus by scanning against each other.

The boards lock against each other by trying to access the PCI bus before
clearing their configuration lock bit. Both boards end up in a loop,
sending and receiving "Target Not Ready" messages forever.

When running in PCI agent mode, the scanning now takes place after the
boards have cleared their configuration lock bit.

Also, add a missing declaration to the mpc83xx.h header file, fixing a
build warning.

46497056ae mpc83xx: Store and display Arbiter Event Register values
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.

ade50c7fa1 mpc83xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.

lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

d9fe88173c MPC83XX: Fix GPIO configuration - set gpio level before direction
Set DAT value before DIR values to avoid creating glitches on the
GPIO signals.

Set gpio level register before direction register to inhibit
glitches on high level output pins.

Dir and data gets cleared at powerup, so high level output lines see
a short low pulse between setting the direction and level registers.

Issue was seen on a new board with the nReset line of the NOR flash
connected to a GPIO. Setting the direction register puts the NOR flash
in reset so the next instruction to set the level cannot get executed.

75b9d4ae0d Pass in tsec_info struct through tsec_initialize
The tsec driver contains a hard-coded array of configuration information
for the tsec ethernet controllers.  We create a default function that works
for most tsecs, and allow that to be overridden by board code.  It creates
an array of tsec_info structures, which are then parsed by the corresponding
driver instance to determine configuration.  Also, add regs, miiregs, and
devname fields to the tsec_info structure, so that we don't need the kludgy
"index" parameter.
