Commit Message

Tomasz Maciej Nowak March 7, 2018, 9:10 p.m. UTC
This commit introduces new subtarget for Marvell EBU Armada Cortex A53
processor based devices.

The first device is Globalscale ESPRESSObin. Some hardware specs:

SoC: Marvell Armada 3700LP (88F3720) dual core ARM Cortex A53
     processor up to 1.2GHz
RAM: 512MB, 1GB or 2GB DDR3
Storage: SATA interface
         µSD card slot with footprint for an optional 4GB EMMC
         4MB SPI NOR flash for bootloader
Ethernet: Topaz Networking Switch (88E6341) with 3x GbE ports
Connectors: USB 3.0
            USB 2.0
            µUSB port connected to PL2303SA (USB to serial bridge
            controller) for UART access
Expansion: 2x 46-pin GPIO headers for accessories and shields with
           I2C, GPIOs, PWM, UART, SPI, MMC, etc
           MiniPCIe slot
Misc: Reset button, JTAG interface

Currently booting only from µSD card is supported.
The boards depending on date of dispatch can come with various U-Boot
versions. For the newest version 2017.03-armada-17.10 no manual
intervention should be needed to boot OpenWrt image. For the older ones
it's necessary to modify default U-Boot environment:

 1. Interrupt boot process to run U-Boot command line,

 2. Run following commands:
    (for version 2017.03-armada-17.06 and 2017.03-armada-17.08)
     setenv bootcmd "load mmc 0:1 0x4d00000 boot.scr; source 0x4d00000"
     saveenv

    (for version 2015.01-armada-17.02 and 2015.01-armada-17.04)
     setenv bootargs "console=ttyMV0,115200 root=/dev/mmcblk0p2 rw rootwait"
     setenv bootcmd "ext4load mmc 0:1 ${fdt_addr} armada-3720-espressobin.dtb; ext4load mmc 0:1 ${kernel_addr} Image; booti ${kernel_addr} - ${fdt_addr}"
     saveenv

 3. Poweroff, insert SD card with OpenWrt image, boot and enjoy.

+Subject: clk: mvebu: armada-37xx-periph: prepare cpu clk to be
+ used with DVFS
+
+When DVFS will be enabled then the cpu clk will use a different set of
+register at run time. That means that we won't be able to use the common
+callback and need to use our own ones.
+
+This patch prepares this change by switching on our own set of callbacks
+without modifying the behavior of the clocks.

+Subject: clk: mvebu: armada-37xx-periph: add DVFS support for cpu clocks
+
+When DVFS is enabled the CPU clock setting is done using an other set of
+registers.
+
+These Power Management registers are exposed through a syscon as they
+will also be used by other drivers such as the cpufreq.
+
+This patch add the possibility to modify the CPU frequency using the
+associate load level matching the target frequency. Then all the
+frequency switch is handle by the hardware.

+Subject: cpufreq: Add DVFS support for Armada 37xx
+
+This patch adds DVFS support for the Armada 37xx SoCs
+
+There are up to four CPU frequency loads for Armada 37xx controlled by
+the hardware.
+
+This driver associates the CPU load level to a frequency, then the
+hardware will switch while selecting a load level.
+
+The hardware also can associate a voltage for each level (AVS support)
+but it is not yet supported

+Subject: spi: a3700: Change SPI mode before asserting chip-select
+
+The spi device mode should be configured in the controller before the
+chip-select is asserted, so that a clock polarity configuration change
+is not interpreted as a clock tick by the device.
+
+This patch moves the mode setting to the 'prepare_message' function
+instead of the 'transfer_one' function.
+
+By doing so, this patch also removes redundant code in
+a3700_spi_clock_set.
+
+This was tested on EspressoBin board, with spidev.

+The PCI configuration space read/write functions were special casing
+the situation where PCI_SLOT(devfn) != 0, and returned
+PCIBIOS_DEVICE_NOT_FOUND in this case.
+
+However, will this is what is intended for the root bus, it is not
+intended for the child busses, as it prevents discovering devices with
+PCI_SLOT(x) != 0. Therefore, we return PCIBIOS_DEVICE_NOT_FOUND only
+if we're on the root bus.

+Since the Aardvark does not implement a PCIe root bus, the Linux PCIe
+subsystem will not align the MAX payload size between the host and the
+device. This patch ensures that the host and device have the same MAX
+payload size, fixing a number of problems with various PCIe devices.
+
+This is part of fixing bug
+https://bugzilla.kernel.org/show_bug.cgi?id=196339, this commit was
+reported as the user to be important to get a Intel 7260 mini-PCIe
+WiFi card working.

+
+The Aardvark has two interrupts sets:
+
+ - first set is bit[23:16] of PCIe ISR 0 register(RD0074840h)
+
+ - second set is bit[11:8] of PCIe ISR 1 register(RD0074848h)
+
+Only one set should be used, while another set should be masked.
+
+The second set, ISR1, is more advanced, the Legacy INT_X status bit is
+asserted once Assert_INTX message is received, and de-asserted after
+Deassert_INTX message is received. Therefore, it matches what the
+driver is currently doing in the ->irq_mask() and ->irq_unmask()
+functions. The ISR0 requires additional work to deassert the
+interrupt, which the driver doesn't do currently.
+
+This commit resolves a number of issues with legacy interrupts.
+
+This is part of fixing bug
+https://bugzilla.kernel.org/show_bug.cgi?id=196339, this commit was
+reported as the user to be important to get a Intel 7260 mini-PCIe

+
+Some PCIe devices do not support LOS, and will cause timeouts if the
+root complex forces the LOS state. This patch disables the LOS state
+by default.
+
+This is part of fixing bug
+https://bugzilla.kernel.org/show_bug.cgi?id=196339, this commit was
+reported as the user to be important to get a Intel 7260 mini-PCIe
+WiFi card working.

+
+There is an obvious typo issue in the definition of the PCIe maximum
+read request size: a bit shift is directly used as a value, while it
+should be used to shift the correct value.
