Alternate SDRAM DDR autocalibration routine that can be generically used
for any PPC4xx chips that have the IBM SDRAM Controller core allowing for
support of more DIMM/memory chip vendors and gets the DDR autocalibration
values which give the best read latency performance (SDRAM0_RDCC.[RDSS]).
Two alternate SDRAM DDR autocalibration algoritm are provided in this patch,
"Method_A" and "Method_B". DDR autocalibration Method_A scans the full range
of possible PPC4xx SDRAM Controller DDR autocalibration values and takes a
lot longer to run than Method_B. Method_B executes in the same amount of time
as the currently existing DDR autocalibration routine, i.e. 1 second or so.
Normally Method_B is used and it is set as the default method.
The current U-Boot PPC4xx DDR autocalibration code calibrates the IBM SDRAM
Controller registers.[bit-field]:
1) SDRAM0_RQDC.[RQFD]
2) SDRAM0_RFDC.[RFFD]
This alternate PPC4xx DDR autocalibration code calibrates the following
IBM SDRAM Controller registers.[bit-field]:
1) SDRAM0_WRDTR.[WDTR]
2) SDRAM0_CLKTR.[CKTR]
3) SDRAM0_RQDC.[RQFD]
4) SDRAM0_RFDC.[RFFD]
and will also use the calibrated settings of the above four registers that
produce the best "Read Sample Cycle Select" value in the SDRAM0_RDCC.[RDSS]
register.[bit-field].

This patch provides an unificated way of handling xilinx v5 ppc440 boards.
It unificates 3 different things:
1) Source code
A new board called ppc440-generic has been created. This board includes
a generic tlb initialization (Maps the whole memory into virtual) and
defines board_pre_init, checkboard, initdram and get_sys_info weakly,
so, they can be replaced by specific functions.
If a new board needs to redefine any of the previous functions
(specific initialization) it can create a new directory with the
specific initializations needed. (see the example ml507 board).
2) Configuration file
Common configurations are located under configs/xilinx-ppc440.h, this
header file interpretes the xparameters file generated by EDK and
configurates u-boot in correspondence. Example: if there is a Temac,
allows CMD_CONFIG_NET
Specific configuration are located under specific configuration file.
(see the example ml507 board)
3) Makefile
Some work has been done in order to not duplicate work in the Main
Makefile. Please see the attached code.
In order to support new boards they can be implemented in the next way:
a) Simple Generic Board (90% of the time)
Using EDK generates a new xparameters.h file, replace
ppc440-generic/xparameters.h and run make xilinx-ppc440-generic_config
&& make
b) Simple Boards with special u-boot parameters (9 % of the time)
Create a new file under configs for it (use ml507.h as example) and
change your paramaters. Create a new Makefile paragraph and compile
c) Complex boards (1% of the time)
Create a new folder for the board, like the ml507
Finally, it adds support for the Avnet FX30T Evaluation board, following
the new generic structure:
Cheap board by Avnet for evaluating the Virtex5 FX technology.
This patch adds support for:
- UartLite
- 16MB Flash
- 64MB RAM
Prior using U-boot in this board, read carefully the ERRATA by Avnet
to solve some memory initialization issues.

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.

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.

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.

The 8544DS and 8572DS platforms support an optional SGMII riser card to
expose ethernet over an SGMII interface. Once the card is in, it is also
necessary to configure the board such that it uses the card, rather than
the on-board ethernet ports. This can either be done by flipping dip switches
on the motherboard, or by modifying registers in the pixis. Either way
requires a reboot.
This adds a command to allow users to choose which ports are routed through
the SGMII card, and which through the onboard ports. It also allows users
to revert to the current switch settings.
This code does not work on the 8572, as the PIXIS is different.

The 8544DS and 8572DS systems have an optional SGMII riser card which
exposes new ethernet ports which are connected to the eTSECs via an
SGMII interface. The SGMII PHYs for this board are offset from the standard
PHY addresses, so this code modifies the passed in tsec_info structure to
use the SGMII PHYs on the card, instead.
