Alexander Graf fa08d39517 PPC 85xx: Add qemu-ppce500 machine
For KVM we have a special PV machine type called "ppce500". This machine
is inspired by the MPC8544DS board, but implements a lot less features
than that one.

It also provides more PCI slots and is supposed to be enumerated by
device tree only.

This patch adds support for the generic ppce500 machine and tries to
rely solely on device tree for device enumeration.

On BSC9131, BSC9132, P1010 : For High Capacity SD Cards (> 2 GBytes), the
32-bit source address specifies the memory address in block address
format. Block length is fixed to 512 bytes as per the SD High Capacity
specification. So we need to convert the block address format
to byte address format to calculate the envaddr.

If there is no enough space for environment variables or envaddr
is larger than 4GiB, we relocate the envaddr to 0x400. The address
relocated is in the front of the first partition that is assigned
for sdboot only.

Priyanka Jain 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

                             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.

So this method is not flexible.

Now a function to get the address of a requested capability is added and used.
It can get the address dynamically by capability ID.
The step of this function:
	1. Read Status register in PCIe configuration space to confirm that

	2. Find the address of Capabilities Pointer Register.

Wolfgang Denk 1b387ef55c SPDX: fix IBM-pibs license identifier
The SPDX License List version 1.19 now contains an official entry for
the IBM-pibs license.  However, instead of our suggestion "ibm-pibs",
the SPDX License List uses "IBM-pibs", with the following rationale:
"The reason being that all other SPDX License List short identifiers
tend towards using capital letters unless spelling a word.  I'd prefer
to be consistent to this end".

Change the license IDs to use the official name.

York Sun 954a1a4776 powerpc/mpc85xx: Add workaround for erratum A-005125
In a very rare condition, a system hang is possible when the e500 core
initiates a guarded load to PCI / PCIe /SRIO performs a coherent write
to memory. Please refer to errata document for more details. This erratum
applies to the following SoCs and their variants, if any.

Shengzhou Liu 424bf94273 powerpc/sec: Add workaround for SEC A-003571
Multiple read/write transactions initiated by security
engine may cause system to hang.
Workaround: set MCFGR[AXIPIPE] to 0 to avoid hang.

Chunhe Lan 9c3f77eb3b fsl_i2c: add workaround for the erratum I2C A004447
This workaround is for the erratum I2C A004447. Device reference
manual provides a scheme that allows the I2C master controller
to generate nine SCL pulses, which enable an I2C slave device
that held SDA low to release SDA. However, due to this erratum,
this scheme no longer works. In addition, when I2C is used as
a source of the PBL, the state machine is not able to recover.

At the same time, delete the reduplicative definition of SVR_VER
and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16
bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro
instead of hard-code value 0x10, 0x11 and 0x20.

The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one
version of platform has this I2C errata. So enable this errata
by IS_SVR_REV(svr, maj, min) function.
