af4c271c33 arm64: mvebu: armada-8040-db.dts: Add I2C and SPI aliases
Add I2C and SPI aliases to enable usage in U-Boot. Otherwise U-Boot will
not be able to use the SPI NOR chip for environment storage and use
"i2c dev 0" to select this I2C bus.

a12c92e393 arm64: mvebu: armada-cp110-master.dtsi: Rename comphy DT node names
Since the cp110 slave also has comphy DT nodes, the names need to be
renamed to avoid a name clash. Lets use the common naming scheme:
"cpm_xxx" for master and "cps_xxx" for slave.

96816a843f arm64: mvebu: Add support for the DB-88F8040 Armada 8k devel board
This patch adds the necessary files to support the Marvell Armada 8k
devel board. Most board specfic files are shared with the Armada 7k
boards under the name "armada-8k*". So only minimal changes are
necessary to add this basic board support (except the DT files of
course).

acd3b0760b arm64: mvebu: armada-8k: Only configure xHCI power on DB-88F7040 board
This patch uses of_machine_is_compatible() to detect the board at runtime
and only configured the I2C IO expander for the xHCI power / reset on
the DB-88F7040 board. As this code will be used by other Armada-7k/8k
ports, its necessary to use this runtime detection here.

44402fe709 common: image: Remove FIT header update from image post-processing
After an image is selected out of a FIT blob for further processing we
run an optional, platform specific, post-processing function on this
component. This post-processing may modify the position and size of the
image, so after post-processing we update the location and size for this
image in the FIT header. This can cause problems as the position of
subsequent components in the FIT blob are only referenced by relative
position to the end of the last component. When we resize or move a
component the following components position will be calculated
incorrectly. To fix this, we do not update the FIT header but instead
only update our local understanding of the image data. This also allows
us to re-run post-processing steps if needed.

463dd22531 board: ti: dra71x-evm: Add epprom support
The dra71x-evm is a board based on TI's DRA718 processor targeting BOM-optimized
entry infotainment systems such as display audio and is a software compatible
derivative of the highly successful DRA74 and DRA72 processor families.
More information can be found here[1].

Add epprom detection for dra71-evm.

1b42ab3eda ARM: DRA7: Fixup DSPEVE, IVA and GPU clock frequencies based on OPP
This patch adds support to update the device-tree blob to adjust the
DSP and IVA DPLL clocks pertinent to the selected OPP choice, with
the default being OPP_NOM. The voltage settings are done in u-boot,
but the actual clock configuration itself is done in kernel because
of the following reasons:
1. SoC definition constraints us to NOT to do dynamic voltage
   scaling ever after the initial avs0 setting in bootloader
   - so the voltage must be set in bootloader.
2. The voltage level must be set even if the IP blocks like
   GPU/DSP are unused.
3. The IVA, GPU and DSP DPLLs are not essential for u-boot functionality,
   and similar DPLL clock configuration code has been cleaned up in
   v2014.10 u-boot release. See commit, 02c41535b6 ("ARM: OMAP4/5:
   Remove dead code against CONFIG_SYS_CLOCKS_ENABLE_ALL").

The non-essential DPLLs are configured within the kernel during
the clock init step when parsing the device tree and creating
the clock devices. This approach meets both the u-boot and kernel
needs.
