net: mvneta: Fix fault when wrong device tree

2018-05-14T08:00:15+00:00

The driver does not check id phy_connect failed (for example on wrong
property name in device tree). In such a case a fault occurs and the
CPU is restarted.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

net: mvneta: support setting hardware address

2018-04-13T20:47:31+00:00

mvneta already supports setting the MAC address but this was only done
internally when some other part of U-Boot tries to actually use the
interface. This commit exposes this functionality to the ethernet core
code so that the MAC addresses of all interfaces are configured
correctly even if they are not used before loading Linux.

net: mvneta - Fixed recv() when multiple packets have arrived.

2018-01-15T18:05:19+00:00

This patch fixes a problem in the mvneta driver where if more than
one packet arrives between calls to mvneta_recv(), the additional
descriptors will be marked as free even though only one descriptor
has been read and processed from the receive queue.  This causes
the additional packet(s) to be delayed until the next packet arrives.
>From this point on all packets will be delayed because the receive
queue will contain unprocessed packets but the hardware shows no
busy descriptors.

dm: core: Rename of_device_is_compatible()

2017-06-01T13:03:06+00:00

The of_ prefix conflicts with the livetree version of this function.
Rename it to avoid problems when we add livetree support.

dm: Rename dev_addr..() functions

2017-06-01T13:03:01+00:00

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.
