6a2fa284ae pci: pci_mvebu: Disable config access to PCI host bridge ports
This patch changes the PCI config routines in the Armada XP / 38x driver
to not allow access to the PCIe root ports.

While updating the Armada XP based theadorable to the latest mainline
and testing it with the DM PCI driver I noticed, that the PCI root
bridge was being configured incorrectly. Resulting in the PCIe Intel
WiFi was not working correctly in Linux. With this patch applied, all
PCIe devices work without any issues in Linux again.

44be835d25 arm: mvebu: Espressobin: Set default value for $ethNaddr env variable
On Espressobin board are MAC addresses stored in U-Boot env area. Therefore
they are not present in default_environment[] array constructed at compile
time.

This change puts permanent MAC addresses into default_environment[] array
at board runtime. Espressobin board has enabled DEFAULT_ENV_IS_RW option
and therefore can modify this array.

This change ensure that 'env default -a' does not delete permanent MAC
addresses from Espressobin env storage area.

c4df0f6f31 arm: mvebu: Espressobin: Set default value for $fdtfile env variable
On Espressobin board value for $fdtfile cannot be determined at compile
time and is calculated at board runtime code. This change uses a new option
DEFAULT_ENV_IS_RW to allow modifying default_environment[] array at runtime
and set into it correct value.

This change also ensure that 'env default -a' set correct value to $fdtfile.

93f4048bc2 env: Allow to set default_environment[] from board code via compile option DEFAULT_ENV_IS_RW
This change allows board code to modify default_environment[] array when
compile option DEFAULT_ENV_IS_RW is specified in board config file.

Some board default variables depend on runtime configuration which is not
known at compile time. Therefore allow to set default_environment[] array
as non-const and allow board code to modify it when it is needed.

- allows the U-Boot version number to be included

07c9e683a4 smbios: Allow a few values to come from sysinfo
While static configuration is useful it cannot cover every case. Sometimes
board revisions are encoded in resistor straps and must be read at
runtime.

The easiest way to provide this information is via sysinfo, since the
board can then provide a driver to read whatever is needed.

Add some standard sysinfo options for this, and use them to obtain the
required information.

e9adaa75bb smbios: Add more options for the BIOS version string
At present the version string is obtained from PLAIN_VERSION. Some boards
may want to configure this using the device tree, since the build system
can more easily insert things there after U-Boot itself is built. Add this
option to the code.

Also in some cases the version needs to be generated programmatically,
such as when it is stored elsewhere in the ROM and must be read first.
To handle this, keep a pointer around so that it can be updated later.
This works by storing the last string in the context, since it is easier
than passing out a little-used extra parameter.

Provide a function to update the version string.

At present we pass the ofnode to each function. We also pass the 'eos'

The code can be made more efficient if it keeps information in a

With the new SW tuning App note[1], a custom tuning algorithm is
required for eMMC HS200, HS400 and SD card UHS modes. The algorithm
involves running through the 32 possible input tap delay values and
sending the appropriate tuning command (CMD19/21) for each of them
to get a fail or pass result for each of the values. Typically, the
range will have a small contiguous failing window. Considering the
tuning range as a circular buffer, the algorithm then sets a final
tuned value directly opposite to the failing window.

5b29fd4a8d mmc: am654_sdhci: Add flag for PHY calibration
Not all controllers need calibration for the PHY DLL. Add a DLL_CALIB
flag to indicate the same.

Also move the write of trm_icp and driver strength to the set_clock()
function to match the kernel configuration flow.

c604e204ef mmc: am654_sdhci: Unconditionally switch off DLL in the beginning of ios_post()
There are some speed modes that work without switching the dll on.
Unconditionally switch off the DLL before setting clock frequency to
support this case. The software will automatically enable DLL for speed
modes that require it. This also means the dll_on priv data member is no
longer required.
