doc: really get rid of Documentation/ directory

2019-12-13T18:01:53+00:00

Commit 656d8da9d2 (doc: Remove duplicated documentation directory) got
rid of most of Documentation/. But there's still an obviously useless
.gitignore left behind.

Also, there's a copy of the linux kernel's net/ethernet.txt binding
imported from v5.0, while the existing one in doc/ is from 4.0-rc1. So
replace the latter by the former, and making Documentation/ finally
empty.

- Increase stack size to avoid a stack overflow during distro boot.
- Add hifive-unleashed-a00.dts for SIFIVE FU540.
- Add OF_SEPARATE support for SIFIVE FU540.
- Add SPL support for Andes AX25 AE350.
- Improve U-Boot SPL / OpenSBI smp boot flow for RISC-V.

doc: update AX25-AE350 RISC-V documentation

2019-12-10T00:23:10+00:00

Add descriptions about U-Boot SPL feature and how to build and run.

Use dts support from U-Boot via OF_SEPARATE instead of depending from opensbi.

2019-12-10T00:23:10+00:00

This would help to make the necessary changes in drivers and device trees
in U-Boot tree itself. This feature would also be helpful to not pass
dtb during opensbi builds.

doc: bindings: Aquantia PHY node binding

2019-12-09T15:47:43+00:00

A couple of optional properties have been introduced for Aquantia PHY
allowing the driver to set up wiring related configuration points that
are otherwise driven by firmware.

doc: bindings: add bindings document for PHY nodes

2019-12-09T15:47:43+00:00

It defines that PHY nodes must be children on MDIO bus nodes and defines
the only required property in U-Boot, reg.  This property along with the
example provided are copied over from Linux.

dt-bindings: phy: dp83867: Add documentation for disabling clock output

2019-12-09T15:47:42+00:00

Based on commit 980066e6d964 ("dt-bindings: phy: dp83867: Add documentation
for disabling clock output") of mainline linux kernel.

The clock output is generally only used for testing and development and not
used to daisy-chain PHYs.  It's just a source of RF noise afterward.

Add a mux value for "off".  I've added it as another enumeration to the
output property.  In the actual PHY, the mux and the output enable are
independently controllable.  However, it doesn't seem useful to be able
to describe the mux setting when the output is disabled.

Document that PHY's default setting will be left as is if the property
is omitted.

net: Always build the string_to_enetaddr() helper

2019-12-09T15:47:41+00:00

Part of the env cleanup moved this out of the environment code and into
the net code. However, this helper is sometimes needed even when the net
stack isn't included.

Move the helper to lib/net_utils.c like it's similarly-purposed
string_to_ip(). Also rename the moved function to similar naming.
