At present there is an offset of one added during the creation of
block device. This can be very confusing as we wanted to encode the
namespace id in the block device name but namespae id cannot be zero.

This changes to use the namespace id directly in the block device
name, eliminating the offset of one effectively.

At present for each namespace there is a block device created for it.
There is no issue if the number of supported namespaces reported from
the NVMe device is only 1.

Since QEMU commit 7f0f1acedf15 ("hw/block/nvme: support multiple namespaces"),
the number of supported namespaces reported has been changed from 1
to 256, but not all of them are active namespaces. The actual active
one depends on the QEMU command line parameters. A common case is
that namespace 1 being active and all other 255 being inactive.

If a namespace is inactive, the namespace identify command returns a
zero filled data structure. We can use field NSZE (namespace size) to
decide whether a block device should be created for it.

At present the block device creation happens in the NVMe uclass
driver post_probe() phase. In preparation to support multiple
namespaces, we should issue namespace identify before creating
block devices but that touches the underlying hardware hence it
is not appropriate to do such in the uclass driver post_probe().
Let's move it to driver probe() phase instead.

When switching to kernel.org x86_64 gcc 11.1.0 toolchain, u-boot.rom
built from qemu-x86_defconfig no longer boots anymore. Investigation
shows that U-Boot fails at a very early stage during the boot process,
in fdtdec_prepare_fdt() where fdt_check_header() complains that there
is not a valid device tree found at gd->fdt_blob which points to _end.
Now _end points to an allocated section .note.gnu.property which of
course is wrong.

This issue is however not seen when using the default Ubuntu 20.04 gnu
toolchain (gcc 9.3.0 with binutils 2.34). Further investigation shows
that it is caused by a behavior change of binutils v2.36 which is part
of the kernel.org gcc 11.1.0 toolchain, via the following commit:

  939b95c77bf2 ("Linux/x86: Configure gas with --enable-x86-used-note by default")

In fact, there was already a regression bug report [1] for binutils two
months ago, but the binutils folks did not think it is a bug :(

To resolve this, there are several options:

* pass -Wa,-mx86-used-note=no to gas
* pass -R .note.gnu.property to objcopy
* discard the section in the linker script

Linux kernel uses the discard way [2], so let's do the same for U-Boot.

Linux uses the prefix "ethernet" whereas u-boot uses "eth". This is from
the linux tree:

$ grep "eth[0-9].*=.*&" arch/**/*dts{,i}|wc -l
0
$ grep "ethernet[0-9].*=.*&" arch/**/*dts{,i}|wc -l
633

In u-boot device trees both prefixes are used. Until recently the only
user of the ethernet alias was the sandbox test device tree. This
changed with commit fc054d56 ("net: Introduce DSA class for Ethernet
switches"). There, the MAC addresses are inherited based on the devices
sequence IDs which is in turn given by the device tree.

Before there are more users in u-boot and both worlds will differ even
more, rename the alias prefix to "ethernet" to match the linux ones.
Also adapt the test cases and rename any old aliases in the u-boot
device trees.

before relocation.

This patch introduces the CONFIG_T2080RDB_REV_D option to signal that a

The default behavior in the latest u-boot revisions is to rotate the
active net device to the next available if the requested link is not
established.

For our ls102x based devices this would mean that if active debug net
device is not available, u-boot will rotate and set the next net device
that is one of the estar adapters.
To return from this situation manual action to set correct ethact
adapter will be needed and this can be annoying when working in
debug mode.

Setting ethrotate=no will disable net adapter rotation and will make sure
