377ffcfabf powerpc/mpc85xx: Add workaround to enable TDM on T1040
This is a workaround for 32 bit hardware limitation of TDM.
T1040 has 36 bit physical addressing, TDM DMAC register
are 32 bit wide but need to store address of CCSR space
which lies beyond 32 bit address range. This workaround
creats a LAW to enable access of TDM DMA to CCSR by
mapping CCSR to overlap with DDR.
A hole of 16M is created in memory using device tree. This
workaround law is set only if "tdm" is defined in hwconfig.
Also disable POST tests and add LIODN for TDM

b6808cd82d powerpc/serdes: Add the workaround for erratum A-007186
SerDes PLL is calibrated at reset. When the junction temperature
delta from the time the PLL is calibrated exceeds +56C/-66C,
jitter may increase and can cause PLL to unlock.

This workaround overwrite the SerDes registers with new values,
to calibrate SerDes registers.
These values are known to work fine for all temperature ranges.

This workaround is valid for B4, T4 and T2 platforms, so
added in their config.

0c12a1592c powerpc/85xx: Enhance get_sys_info() to check clocking mode
T1040 and it's variants provide "Single Oscillator Source" Reference Clock Mode.

In this mode, single onboard oscillator(DIFF_SYSCLK) can provide the reference clock
(100MHz) to the following PLLs:
• Platform PLL
• Core PLLs
• USB PLL
• DDR PLL, etc

The cfg_eng_use0 of porsr1 register identifies whether the SYSCLK (single-ended) or
DIFF_SYSCLK (differential) is selected as the clock input to the chip.

get_sys_info has been enhanced to add the diff_sysclk so that the
various drivers can be made aware of ths diff sysclk configuration and
act accordingly.

Other changes:
-single_src to ddr_refclk_sel, as it is use for checking ddr reference clock
-Removed the print of single_src from get_sys_info as this will be
-printed whenever somebody calls get_sys_info which is not appropriate.
-Add print of single_src in checkcpu as it is called only once during initialization

c3678b0937 powerpc/mpc85xx: Add workaround for erratum A007212
Erratum A007212 for DDR is about a runaway condition for DDR PLL
oscilliator. Please refer to erratum document for detail.
For this workaround to work, DDR PLL needs to be disabled in RCW.
However, u-boot needs to know the expected PLL ratio. We put the
ratio in a reserved field RCW[18:23]. U-boot will skip this workaround
if DDR PLL ratio is set, or the reserved field is not set.

Workaround for erratum A007212 applies to selected versions of
B4/T4 SoCs. It is safe to apply the workaround to all versions. It
is helpful for upgrading SoC without changing u-boot. In case DDR
PLL is disabled by RCW (part of the erratum workaround), we need this
u-boot workround to bring up DDR clock.

b135991a3c powerpc/mpc85xx: Add support for single source clocking
Single-source clocking is new feature introduced in T1040.
In this mode, a single differential clock is supplied to the
DIFF_SYSCLK_P/N inputs to the processor, which in turn is
used to supply clocks to the sysclock, ddrclock and usbclock.

So, both ddrclock and syclock are driven by same differential
sysclock in single-source clocking mode whereas in normal clocking
mode, generally separate DDRCLK and SYSCLK pins provides
reference clock for sysclock and ddrclock

DDR_REFCLK_SEL rcw bit is used to determine DDR clock source
-If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
 normal clocking mode by DDR_Reference clock

-If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
 single source clocking mode by DIFF_SYSCLK

Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

  fsl,liodn-offset-list = <0 0xffffffcd 0xffffffcf
                             0xffffffd1 0xffffffd3

                             0xffffffd9 0xffffffdb>;

The update consists in adding a parameter to the
function that builds the list to specify the base
liodn.
On PCI v2.4 use the old base = 256 and, on PCI 3.0
where some of the PCIE liodns are larger than 256,
use a base = 1024. The version check is based on
the PCI controller's version register.

f69814397e powerpc/chassis2: Change core numbering scheme
To align with chassis generation 2 spec, all cores are numbered in sequence.
The cores may reside across multiple clusters. Each cluster has zero to four
cores. The first available core is numbered as core 0. The second available
core is numbered as core 1 and so on.

Core clocks are generated by each clusters. To identify the cluster of each
core, topology registers are examined.

Cluster clock registers are reorganized to be easily indexed.

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.

When compile the slave image for boot from SRIO, no longer need to
specify which SRIO port it will boot from. The code will get this
information from RCW and then finishes corresponding configurations.

This has the following advantages:
	1. No longer need to rebuild an image when change the SRIO port for
	   boot from SRIO, just rewrite the new RCW with selected port,
	   then the code will get the port information by reading new RCW.
	2. It will be easier to support other boot location options, for

5ffa88eca7 powerpc/corenet_ds: Master module for boot from SRIO
For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.

The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image in master NOR flash.
	3. Normally boot from local NOR flash.
	4. Configure SRIO switch system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to SRIO1 or SRIO2 by RCW.
	3. RCW should configure the SerDes, SRIO interfaces correctly.
	4. Slave must be powered on after master's boot.

For the master module, need to finish these processes:
	1. Initialize the SRIO port and address space.
	2. Set inbound SRIO windows covered slave's u-boot image stored in
	   master's NOR flash.
	3. Master's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_MASTER_config
	4. Master must boot first, and then slave can be powered on.

The Frame Manager (FMan) on QorIQ SoCs with DPAA (datapath acceleration
architecture) is the ethernet contoller block.  Normally it is utilized
via Queue Manager (Qman) and Buffer Manager (Bman).  However for boot
usage the FMan supports a mode similar to QE or CPM ethernet collers
called Independent mode.

Additionally the FMan block supports multiple 1g and 10g interfaces as a
single entity in the system rather than each controller being managed
uniquely.  This means we have to initialize all of Fman regardless of
the number of interfaces we utilize.

Different SoCs support different combinations of the number of FMan as
well as the number of 1g & 10g interfaces support per Fman.

We add support for the following SoCs:
 * P1023 - 1 Fman, 2x1g
 * P4080 - 2 Fman, each Fman has 4x1g and 1x10g
 * P204x/P3041/P5020 - 1 Fman, 5x1g, 1x10g

28747f9bb1 powerpc/85xx: Add SERDES support for P1010/P1014
Add the ability to determine if a given IP block connected on SERDES is
configured. This is useful for things like PCIe and SRIO since they are only
ever connected on SERDES.

Updated MPC85xx_PORDEVSR_IO_SEL & MPC85xx_PORDEVSR_IO_SEL_SHIFT

d2a9568c57 mpc85xx: Adding more registers and options
This patch exposes more registers which can be used by the DDR drivers or
interactive debugging. U-boot doesn't use all the registers in DDRC.
When advanced tuning is required, writing to those registers is needed.

Add writing to cdr1, cdr2, err_disable, err_int_en and debug registers
Add options to override rcw, address parity to RDIMMs.
Use array for debug registers.

17028be238 Fix wrong CONFIG_SYS_MPC85xx_SERDES1_ADDR
CONFIG_SYS_MPC85xx_SERDES1_ADDR was defined wrong as
CONFIG_SYS_IMMR + CONFIG_SYS_MPC85xx_SERDES2_OFFSET.
It should be as
CONFIG_SYS_IMMR + CONFIG_SYS_MPC85xx_SERDES1_OFFSET.
