Looks like the datasheet at

is wrong, and the testing was poorly done, because the PMECC did not raise
any error, but also didn't correct any bitflips. Restoring the offsets
as they were before, makes the PMECC on sama5d3x capable of correcting
bitflips.

For boards with a second Ethernet interface, however, we would

Merge tag 'u-boot-atmel-2020.04-a' of https://gitlab.denx.de/u-boot/custodians/u-boot-atmel
First set of u-boot-atmel features for 2020.04 cycle
This feature set is a patch series from Tudor Ambarus which includes
parsing of the spi flash SFDP parser for SST flashes, and using those
tables to retrieve unique saved per device MAC address. This is then
used as base mac address on the SAMA5D2 Wireless SOM EK board.
The SST26VF064BEUI spi-nor flash is programmed at the factory with a
globally unique address stored in the SFDP vendor parameter table and
it is permanently writeprotected. Retrieve the EUI-48 address and set it
as ethaddr env.

At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.
Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.
Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.
This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

When introducing the SAMA5D27 SoCs, the SAMA5D2 series got an additional
chip id. The check if the cpu is sama5d2 was changed from a preprocessor
definition (inlining a call to 'get_chip_id()') to a C function,
probably to not call get_chip_id twice?
That however broke a check in the macb ethernet driver. That driver is
more generic and also used for other platforms. I suppose this solution
was implemented to use it in 'gem_is_gigabit_capable()', without having
to stricly depend on the at91 platform:
#ifndef cpu_is_sama5d2
#define cpu_is_sama5d2() 0
#endif
That only works as long as cpu_is_sama5d2 is a preprocessor definition.
(The same is still true for sama5d4 by the way.) So this is a straight
forward fix for the workaround.
The not working check on the SAMA5D2 CPU lead to an issue on a custom
board with a LAN8720A ethernet phy connected to the SoC:
=> dhcp
ethernet@f8008000: PHY present at 1
ethernet@f8008000: Starting autonegotiation...

Notice the wrong reported link speed, although both SoC and phy only

ethernet mac IP block, is probably more complicated, though.

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.
