At BDF address 00:00.0 is fictional device which PCI configuration header
is for configuring mpc85xx PCI controller itself. PCI config space of this
device has ATMU inbound registers on position of PCI BARs. Trying to do PCI
auto configuration of this device cause rewriting ATMU inbound registers.
To avoid it, do not allow overwriting registers at BARs positions. And
because this device does not have any PCI memory, return zeros when trying
to read PCI BARs config space registers. It signals to auto configuration
tool to not allocate any PCI memory for this device.

as opposite of the PCIe driver pcie_fsl.c for the same platform.
So do not try to access extended PCIe registers as it cannot work.

Please pull the second part of the sunxi pull request for this cycle.
Another bunch of patches that replace old-school U-Boot hacks with
proper DM based code, this time for the raw NAND flash driver, and the
USB PHY VBUS detection code. Plus two smaller patches that were sitting
in my inbox for a while.
Gitlab CI passed. In lack of some supported board with NAND flash I
couldn't really test this part, but apparently this was tested by the
reviewer. I briefly ran the branch on some boards with USB-OTG, and
this still worked.
This pull request adds support for the last CPU board from
CS GROUP France (previously CSSI).
That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence
its name) and can be plugged in place of the CMPC885 board.
In order to support that new board, the following changes are included
in this series:
- Make the mpc8xx watchdog driver more generic for reusing it
with mpc83xx
- Fix various small problems on mpc83xx platform
- Add a GPIO Driver for QE GPIOs
- Add support for mpc832x into mpc83xx SPI driver
- Refactor existing board code that will be shared with new board
- Add the new board
For the devfdt_get_addr_index_ptr() and devfdt_get_addr_size_index_ptr()
function use map_sysmem() function as cast for the return for use in
sandbox. Also fix sandbox test.

add nvmxip_qspi driver under UCLASS_NVMXIP
The device associated with this driver is the parent of the blk#<id> device
nvmxip_qspi can be reused by other platforms. If the platform
has custom settings to apply before using the flash, then the platform
can provide its own parent driver belonging to UCLASS_NVMXIP and reuse
nvmxip-blk driver. The custom driver can be implemented like nvmxip_qspi in
addition to the platform custom settings.
Platforms can use multiple NVM XIP devices at the same time by defining a
DT node for each one of them.

add block storage emulation for NVM XIP flash devices
Some paltforms such as Corstone-1000 need to see NVM XIP raw flash
as a block storage device with read only capability.
Here NVM flash devices are devices with addressable
memory (e.g: QSPI NOR flash).
The implementation is generic and can be used by different platforms.
Two drivers are provided as follows.
nvmxip-blk :
a generic block driver allowing to read from the XIP flash
nvmxip Uclass driver :
When a device is described in the DT and associated with
UCLASS_NVMXIP, the Uclass creates a block device and binds it with
the nvmxip-blk.
Platforms can use multiple NVM XIP devices at the same time by defining a
DT node for each one of them.
