a836626cc4 powerpc/85xx: wait for alignment before resetting SERDES RX lanes (SERDES9)
The work-around for P4080 erratum SERDES9 says that the SERDES receiver
lanes should be reset after the XAUI starts tranmitting alignment signals.

2a523f5240 fdt: Add new fdt_set_node_status & fdt_set_status_by_alias helpers
Add common function fdt_set_node_status() to assist in various locations
that we set a nodes status.  This function utilizes the status values
that are part of the EPAPR spec (on power.org).

fdt_set_status_by_alias() is based on fdt_set_node_status() but uses an
alias string to identify the node to update.

We also add some shortcut functions to help the common cases of setting
"okay" and "disabled":

	fdt_status_okay()
	fdt_status_disabled()
	fdt_status_okay_by_alias()
	fdt_status_disabled_by_alias()

Finally, we fixup the corenet_ds ethernet code which previously had
a function by the same name that can be replaced with the new helpers.

464c79207c punt unused clean/distclean targets
The top level Makefile does not do any recursion into subdirs when

never get used.  Punt them all.

712cf7ab0b powerpc/mpc8xxx: Merge entries in DDR speed table
It is not necessary to keep multiple entries for the same setting in DDR
speed tables. Merge them for smaller tables. Also restructure the tables
for smaller size. Cleanup some typedefs.

Enforce strict checking for speed table. If DIMM is running at higher than
known speed, try to use the highest speed setting. If rank is unknown, it
has to panic.

Removed ODT overriding for P2020DS as it is not necessary.

360275b362 powerpc/85xx: refactor common P-Series CoreNet files for FSL boards
We currently support 4 SoC/Boards from the P-Series of QorIQ SoCs that
are based on the 'CoreNet' Architecture: P2041RDB, P3041DS, P4080DS, and
P5020DS.  There is a significant amount of commonality shared between
these boards that we can refactor into common code:

* Initial LAW setup
* Initial TLB setup
* PCI setup

We start by moving the shared code between P3041DS, P4080DS, and P5020DS
into a common directory to be shared with other P-Series CoreNet boards.

cba4614862 powerpc/hydra: Add ethernet support on P5020/P3041 DS boards
Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P3041DS &
P5020DS ("Hydra").

The lane_to_slot[] array is initialized dynamically, since board switches
can be used to control the muxing of SERDES lanes to slots.

The BRDCFG1 PIXIS register is used to route the MII bus to the appropriate
slot.  The SERDES configuration is queried to help determine the routing
between MACs and slot/phy combination.

If a XAUI card is inserted, muxing for that card is enabled and never
turned off.  The PHY address for the 10G XAUI card depends on the slot in
which it's inserted.  If it's in slot 1, the address is 4.  If it's in
slot 2, the address is 0.

Update the MDIO routing in the P3041DS and P5020DS device trees based on
the board-level muxing.  The SERDES configuration determines which
SGMII/XGMII boards are located in which slots, and so the MDIO bus needs
to be muxed correctly whenever talking to a PHY connected to any Fman MAC.
The Fman Ethernet nodes in the device tree also need to be routed to the
correct PHYs.

Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

2915609a91 powerpc/85xx: Add FMan ethernet support to P4080DS
Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P4080DS.

The board supports add-on cards for SGMII and XAUI functionality.  Which
slots on the board these cards are in is a function of the SERDES option
selected and muxes on the board.

Additionally because of the high-configurablity which MDIO bus one is
connected to is "selected" via an FPGA register.  We create dummy MDIO
bus for the phy layer and hide the mux manipulation in this dummy layer.

Add fman fdt helper function in board common code it'll be used by several
freescale boards that do various muxing of the MDIO signals based on which
controller/interface one is trying to talk to.

Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

Moved the SRIO init out of corenet_ds and into common code for
8xxx/QorIQ processors that have SRIO.  We mimic what we do with PCIe
controllers for SRIO.

We utilize the fact that SRIO is over serdes to determine if its

We additionally update the device tree (to remove the SRIO nodes) if the
board doesn't have SRIO enabled.

Introduced the following standard defines for board config.h:

CONFIG_SYS_SRIO - Chip has SRIO or not
CONFIG_SRIO1 - Board has SRIO 1 port available
CONFIG_SRIO2 - Board has SRIO 2 port available

(where 'n' is the port #)
CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot
CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup)
CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup)

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

2ae1824196 Makefile: move all Power Architecture boards into boards.cfg
Clean up Makefile, and drop a lot of the config.mk files on the way.

We now also automatically pick all boards that are listed in
boards.cfg (and with all configurations), so we can drop the redundant
entries from MAKEALL to avoid building these twice.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

1bf8e9fd74 powerpc/85xx: Add support for 4th PCI controller on corenet_ds

0e159024ea powerpc/85xx: Fix SRIO LAW setup on corenet_ds boards
In function board_early_init_r(), serdes will not be initialize yet.
Thus sRIO was always considered disabled.  Move the check for sRIO into
misc_init_r() which is called after fsl_serdes_init().

Also, fixed warning associated with gur variable possibly not being
used.

90870d9846 powerpc/8xxx: Fix quad-rank DIMMs support on corenet_ds board.
The board specific parameters associated with quad rank dimms where
missing.  This fixes it so the board will function if quad rank dimms
are placed in it.
