rockchip: rk3399: spl: make SPL boot-order configurable via /chosen

2017-04-05T02:01:57+00:00

The RK3399 does not have any boot selection pins and the BootROM probes
the boot interfaces using the following boot-order:
    1. SPI
    2. eMMC (sdhci in DTS)
    3. SD card (sdmmc in DTS)
    4. USB loader
For ease of deployment, the SPL stage should mirror the boot order of
the ROM and use the same probing order (assuming that valid images can
be detected by SPL) unless instructed otherwise.  The boot-order can
then be configured via the 'u-boot,spl-boot-order' property in the
chosen-node of the DTS.

While this approach is easily extensible to other boards, it is only
implemented for the RK3399 for now, as the large SRAM on the RK3399
makes this easy to fit the needed infrastructure into SPL and our
production setup already runs with DM, OF_CONTROL and BLK in SPL.

The new boot-order property is expected to be used in conjunction with
FIT images (and all legacy image formats disabled via Kconfig).

A boot-sequence with probing and fallthroughs from SPI via eMMC to SD
card (i.e. &spiflash, &sdhci, &sdmmc) has been validated on the RK3399-Q7.

drivers/net/phy: add fixed-phy / fixed-link support

2017-03-26T14:58:26+00:00

This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).

For this purpose we introduce a new phy-driver, called "Fixed PHY".

Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.

Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).

During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.

2017-03-24T12:19:30+00:00

This replaces legacy arch/arc/lib/timer.c implementation and allows us
to describe ARC Timers in Device Tree. Among other things that way we
may properly inherit Timer's clock from CPU's clock s they really run
synchronously.

drivers: timer: Introduce ARC timer driver

2017-03-24T11:20:55+00:00

This commit introduces timer driver for ARC.

ARC timers are configured via ARC AUX registers so we use special
functions to access timer control registers.

This driver allows utilization of either timer0 or timer1
depending on which one is available in real hardware. Essentially
only existing timers should be mentioned in board's Device Tree
description.

mvebu: usb: xhci: Add VBUS regulator supply to the host driver

2017-03-23T07:45:25+00:00

The USB device should linked to VBUS regulator through "vbus-supply"
DTS property.
This patch adds handling for "vbus-supply" property inside the USB
device entry for turning on the VBUS regulator upon the host adapter probe.
