[PATCH v2 0/3] xilinx: Enable Versal allocation from low memory

[Michal Simek]

Hi,

Generated DTS files don't need to have memory nodes sorted out that's why
it can happen that the first memory node is not pointing to lowest DDR
which is normally used for system boot. That's why new function was
introduced which finds out the lowest memory available and use it for
u-boot and later can be also used for OS.

The series is based on
https://lists.denx.de/pipermail/u-boot/2020-July/419656.html
which simplified conversion to livetree API which was asked by Simon.

And also I keep conversion to livetree in separate patch on the top of v1
which shouldn't be a problem.

The series is still missing tests which Simon asked for but I would like to
get feedback about these patches. If they are fine I would like to have
discussion how/where to write little test for it.

Thanks,
Michal

Changes in v2:
- Separate Xilinx change from generic patch
- new patch asked by Simon
- split from generic patch sent in v1
