9d86b89c59 dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h>
The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.

Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.

If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.

Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

5ccd657b6d net: macb: Fix rx buffer cache handling
With commit c6d07bf440 ("net/macb: increase RX buffer size for GEM")
ethernet support does not work any more with d-cache enabled on the
AT91SAM. The reason is, that MACB_RX_BUFFER_SIZE was changed from 4096
to 128 but this change was not refected in the rx_buffer flush and
invalidate functions, as these also use this macro.

This patch now fixes this by calculating the rx buffer size correctly
again in those functions. With this change, ethernet works again
reliably on my AT91SAM board.

In 10/100 MII mode, transmit logic must be clocked from a free

the controller, not the external PHY, must generate the 125 MHz
transmit clock towards the PHY.

I've noticed that the first ethernet packet after PHY link establishment

on the first packet is not seen any more.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

a821c4af79 dm: Rename dev_addr..() functions
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.

otherwise (at least on ARM926-EJS) the request is ignored. When the cache
is enabled this means that packets are not sent.

75b03cf14c net: macb: Not all the GEM are gigabit capable
During the initialization of PHY the gigabit bit capable is set if the
controller is a GEM. However, for sama5d2 and sama5d4, the GEM is
configured to support only 10/100.

Improperly setting the GBE capability leads to an unresponsive MAC
controller. This patch fixes this behavior allowing using the gmac with
these SoCs.
