      mvebu: cp110: avoid pcie power on/off sequence when called from Linux · 55df84f9
      Igal Liberman authored 
      

In Armada 8K DB boards, PCIe initialization can be executed only once
because PCIe reset performed during chip power on and it cannot be
executed via GPIO later.
This means that power on can be executed only once, when it's called
from the bootloader.
Power on:
	Read bit 21 of the mode, it marks if the caller is
	the bootloader or the Linux Kernel.
Power off:
	Check if the comphy was already configured to PCIe, if yes,
	check if the caller is bootloader, if both conditions are true
	(PCIe mode and called by Linux) - skip the power-off.

In addition, fix incorrect documentation describing mode fields -
PCIe width is 3 bits, not 2.

NOTE: with this patch, please use LK4.14.76 (LK4.4.120 may not work
with it).

      plat: marvell: a3700: do not power off cpu due to errata ref #13 · 9cb6751d
      Grzegorz Jaszczyk authored 
      

Do not power off the CPU1 since there is no way to wake it up
(wake-up is causing CPU0 reset as well duo to HW bug). Quote from errata
Ref #13 [In power saving mode, both cores must be powered off]:
"When Core 0 is on and Core 1 is in power-off state, a Core 1
wake-up resets Core 0 as well and puts Core 0 back to ROM".

To overcome described HW bug instead of powering the CPU off, let it
reach WFI instruction, which is invoked by generic psci_do_cpu_off
function after platform handler finishes. This will put the core in low
power state and give a chance to wake it up.

Before this change, after running secondary kernel via kexec, only one
core was up, now both cores are up.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

      plat: marvell: Add support for Armada-37xx SoC platform · 1e66bacb
      Konstantin Porotchkin authored 
      

Add supprot for Marvell platforms based on Armada-37xx SoC.
This includes support for the official Armada-3720 modular
development board and EspressoBin community board.
The Armada-37xx SoC contains dual Cortex-A53 Application CPU,
single secure CPU (Cortex-M3) and the following interfaces:
- SATA 3.0
- USB 3.0 and USB 2.0
- PCIe
- SDIO (supports boot from eMMC)
- SPI
- UART
- I2c
- Gigabit Ethernet

      Add plat_crash_console_flush to platforms without it · 9c675b37
      Antonio Nino Diaz authored 
      

Even though at this point plat_crash_console_flush is optional, it will
stop being optional in a following patch.

The console driver of warp7 doesn't support flush, so the implementation
is a placeholder.

TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but
they weren't global so they weren't actually used. Also, they were
calling the wrong functions.

imx8_helpers.S only has placeholders for all of the functions.

      mvebu: cp110: introduce COMPHY porting layer · 42a29337
      Grzegorz Jaszczyk authored 
      

Some of COMPHY parameters depends on the hw connection between the SoC
and the PHY, which can vary on different boards e.g. due to different
wires length. Define the "porting layer" with some defaults
parameters. It ease updating static values which needs to be updated due
to board differences, which are now grouped in one place.

Example porting layer for a8k-db is under:
plat/marvell/a8k/a80x0/board/phy-porting-layer.h

If for some boards parameters are not defined (missing
phy-porting-layer.h), the default values are used
(drivers/marvell/comphy/phy-default-porting-layer.h)
and the following compilation warning is show:
"Using default comphy params - you may need to suit them to your board".

The common COMPHY driver code is extracted in order to be shared with
future COMPHY driver for A3700 SoC platforms

      marvell: Move BLE from external repo to the platform folder · 37c4341b
      Konstantin Porotchkin authored 
      

The BLE is the pre-TF-A boot stage required by Marvell Armada
BootROM for bringing up DRAM and allow the boot image copy to it.
Since this is not a standard boot level and only uses the TF-A
as a build environment, it was introduced out of source tree.
However it turns out that such remote location introduces additional
complexity to the upstream TF-A build process.
In order to simplify the build environment the BLE source folder
is relocated from the external repository to A8K platform directory.
The build documentation is updated accordingly.

      drivers: i2c: mentor: move platform code into header files · dfc0fb27
      Andre Przywara authored 
      

At the moment we have two I2C stub drivers (for the Allwinner and the
Marvell platform), which #include the actual .c driver file.
Change this into the more usual design, by renaming and moving the stub
drivers into platform specific header files and including these from the
actual driver file. The platform specific include directories make sure
the driver picks up the right header automatically.
