72bd83cd0a powerpc/t4240: Adding workaround errata A-005871
When CoreNet Fabric (CCF) internal resources are consumed by the cores,
inbound SRIO messaging traffic through RMan can put the device into a
deadlock condition.

This errata workaround forces internal resources to be reserved for
upstream transactions. This ensures resources exist on the device for
upstream transactions and removes the deadlock condition.

The Workaround is for the T4240 silicon rev 1.0.

db9a807054 powerpc/mpc85xx:Fix Core cluster configuration loop
Different personalities/derivatives of SoC may have reduced cluster. But it is
not necessary for last valid DCFG_CCSR_TP_CLUSTER register to have
DCFG_CCSR_TP_CLUSTER[EOC] bit set to represent "End of Clusters".

EOC bit can still be set in last DCFG_CCSR_TP_CLUSTER register of orignal SoC
which may not be valid for the personality.
So add initiator type check to find valid cluster.

c0a4e6b889 powerpc/p4080ds: fix PCI-e x8 link training down failure
Due to SerDes configuration error, if we set the PCI-e controller link width
as x8 in RCW and add a narrower width(such as x4, x2 or x1) PCI-e device to
PCI-e slot, it fails to train down to the PCI-e device's link width. According
to p4080ds errata PCIe-A003, we reset the PCI-e controller link width to x4 in
u-boot. Then it can train down to x2 or x1 width to make the PCI-e link between
RC and EP.

d607b9684b powerpc/85xx: implement check for erratum A-004580 work-around
The work-around for erratum A-004580 ("Internal tracking loop can falsely
lock causing unrecoverable bit errors") is implemented via the PBI
(pre-boot initialization code, typically attached to the RCW binary).
This is because the work-around is easier to implement in PBI than in
U-Boot itself.

It is still useful, however, for the 'errata' command to tell us whether
the work-around has been applied.  For A-004580, we can do this by verifying
that the values in the specific registers that the work-around says to
update.

This change requires access to the SerDes lane sub-structure in
serdes_corenet_t, so we make it a named struct.

e76cd5d4cf 8xxx: Change all 8*xx_DDR addresses to 8xxx
There were a number of shared files that were using
CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and
several variants (DDR2, DDR3). A recent patchset added
85xx-specific ones to code which was used by 86xx systems.
After reviewing places where these constants were used, and
noting that the type definitions of the pointers assigned to
point to those addresses were the same, the cleanest approach
to fixing this problem was to unify the namespace for the
85xx, 83xx, and 86xx DDR address definitions.

This patch does:

s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g

All 85xx, 86xx, and 83xx have been built with this change.

c97cd1ba48 spl/85xx: new SPL support
Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL
and CONFIG_SPL_BUILD, respectively.  CONFIG_NAND_SPL can be removed once
the last mpc85xx nand_spl target is gone.

CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't
seem right to overload it for meaning SPL as well as nand_spl does.  Even
if it's somewhat appropriate for the main u-boot, the SPL itself isn't
(necessarily) ramboot, and we don't have separate configs for SPL and
main u-boot.  It was also inconsistent, as other platforms such as
mpc83xx didn't use CONFIG_RAMBOOT in this way.

7f0a22ff25 powerpc/mpc85xx: fix TLB alignment
In the RAMBOOT/SPL case we were creating a TLB entry starting at
CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly
aligned for the TLB entry size.  This turned out to not be the case
with NAND SPL because the main U-Boot starts at an offset into the image
in order to skip the SPL itself.

Fix the TLB entry to always start at a proper alignment.  We still assume that
CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary
thus requiring multiple TLB entries.

Currently, the SRIO and PCIE boot master module will be compiled into the
u-boot image if the macro "CONFIG_FSL_CORENET" has been defined. And this
macro has been included by all the corenet architecture platform boards.
But in fact, it's uncertain whether all corenet platform boards support
this feature.

So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add
a special macro for every board which can support the feature. This
special macro will be defined in the header file
"arch/powerpc/include/asm/config_mpc85xx.h". It will decide if the SRIO
and PCIE boot master module should be compiled into the board u-boot image.

a1d558a20f powerpc/mpc85xx: Add workaround for DDR erratum A004934
After DDR controller is enabled, it performs a calibration for the
transmit data vs DQS paths. During this calibration, the DDR controller
may make an inaccurate calculation, resulting in a non-optimal tap point.

eb53941206 powerpc/mpc85xx: software workaround for DDR erratum A-004468
Boot space translation utilizes the pre-translation address to select
the DDR controller target. However, the post-translation address will be
presented to the selected DDR controller. It is possible that the pre-
translation address selects one DDR controller but the post-translation
address exists in a different DDR controller when using certain DDR
controller interleaving modes. The device may fail to boot under these
circumstances. Note that a DDR MSE error will not be detected since DDR
controller bounds registers are programmed to be the same when configured
for DDR controller interleaving.

f31cfd1925 powerpc/mpc8xxx: Fix DDR initialization waiting for D_INIT
When ECC is enabled, DDR controller needs to initialize the data and ecc.
The wait time can be calcuated with total memory size, bus width, bus speed
and interleaving mode. If it went wrong, it is bettert to timeout than
waiting for D_INIT to clear, where it probably hangs.

57495e4e5e powerpc/mpc8xxx: Update DDR registers
DDRC ver 4.7 adds DDR_SLOW bit in sdram_cfg_2 register. This bit needs to be
set for speed lower than 1250MT/s.

CDR1 and CDR2 are control driver registers. ODT termination valueis for
IOs are defined. Starting from DDRC 4.7, the decoding of ODT for IOs is
	000 -> Termsel off
	001 -> 120 Ohm
	010 -> 180 Ohm
	011 -> 75 Ohm
	100 -> 110 Ohm
	101 -> 60 Ohm
	110 -> 70 Ohm
	111 -> 47 Ohm

Add two write leveling registers. Each QDS now has its own write leveling
start value. In case of zero value, the value of QDS0 will be used. These
values are board-specific and are set in board files.

Extend DDR register timing_cfg_1 to have 4 bits for each field.

DDR control driver registers and write leveling registers are added to
interactive debugging for easy access.
