2846c43e2d kmp204x: add workaround for A-004849
This should prevent the problems that the CCF can deadlock with certain
traffic patterns.

This also fixes the workaround for A-006559 that was not correctly
implemented before.

e20c822d0e kmp204x: update the RCW
Fix the IRQ/GPIO settings: all the muxed GPIO/external IRQs that are
used as internal interrupts are defined as GPIOs to avoid confusion
between the internal/external interrupts.

af47faf650 kmp204x: complete the reset sequence and PRST configuration
This adds the reset support for the following devices that was until
then not implemented:
- BFTIC4
- QSFPs

This also fixes the configuration of the prst behaviour for the other
resets: Only the u-boot and kernel relevant subsystems are taken out of
reset (pcie, ZL30158, and front eth phy).

Most of the prst config move to misc_init_f(), except for the PCIe
related ones that are in pci_init_board and the bftic and ZL30158 ones
that should be done as soon as possible.

Only the behavior of the Hooper reset is changed according to the
documentation as the application is not able to not configure the switch
when it is not reset.

18794944c6 kmp204x: selftest/factory test pin support
This patch defines the post_hotkeys_pressed() function that is used for:
- triggering POST memory regions test
- starting the test application through the checktestboot command in
  a script by setting the active bank to testbank

The post_hotkeys_pressed return the state of the SELFTEST pin.

The patch moves from the complete POST-memory test that is too long in
its SLOW version for our production HW test procedure to the much shorter
POST-memory-regions test.

Finally, the unused #defines for the not so relevant mtest command are
removed.

a53e65d053 kmp204x: Add support for the unit LEDs
The unit LEDs are managed by the QRIO CPLD. This patch adds support for
accessing these LEDs in the QRIO.

The LEDs then are set to a correct boot state:
- UNIT-LED is red
- BOOT-LED is on.

27c78e06f2 kmp204x: initial support for PCIe FPGA configuration
The PEXHC PCIe configuration mechanism ensures that the FPGA get
configured at power-up. Since all the PCIe devices should be configured
when the kernel start, u-boot has to take care that the FPGA gets
configured also in other reset scenarios, mostly because of possible
configuration change.

The used mechanism is taken from the km_kirkwood design and adapted to
the kmp204x case (slightly different HW and PCIe configuration).

1f07a71b96 kmp204x: update I2C field of RCW
On the previous HW revision (now unsupported), there was a need for
external DMA signals and thus the I2C3/4 signals were used
DMA1_DONE/ACK/REQ.

These signals now are configured as GPIO[16:19].

fabb9297fa kmp204x: implement workaround for A-006559
According to the errata, some bits of an undocumented register in the
DCSR must be set for every core in order to avoid a possible data or
instruction corruption.

This is required for the 2.0 revision of the P2041 that should be used
as soon as available in our design.

f3e74d0a9f kmp204x: I2C deblocking support
This patch adds support for using some GPIOs that are connected to the
I2C bus to force the bus lines state and perform some bus deblocking
sequences.

The KM common deblocking algorithm from board/keymile/common/common.c is
used. The GPIO lines used for deblocking the I2C bus are some external
GPIOs provided by the QRIO CPLD:
  - SCL = GPIOA_20
  - SDA = GPIOA_21

The QRIO GPIOs act in an open-drain-like manner, for 0 the line is
driven low and for 1 the GPIO is set as input and the line gets
pulled-up.

87ea2c0ff3 kmp204x: introduce QRIO GPIO functions
The QRIO GPIO functions can be of general interest. They are thus added

prst function are also included in this file, as well as the functions
required for the I2C deblocking support (open-drain).

877bfe37dc mpc85xx: introduce the kmp204x reference design support
This patch introduces the support for Keymile's kmp204x reference
design. This design is based on Freescale's P2040/P2041 SoC.

The peripherals used by this design are:
- DDR3 RAM with SPD support
- SPI NOR Flash as boot medium
- NAND Flash
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
  FPGA
- 2 HW I2C busses
- last but not least, the mandatory serial port

The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb
support and was changed according to our design (that means essentially
removing what is not present on the designs and a few adaptations).

There is currently only one prototype board that is based on this design
and this patch also introduces it. The board is called kmlion1.
