e716c90229 Revert "doc: update Kernel documentation build system"
Unfortunately we now see a number of now-fatal warnings about duplicate
labels.  It is often unclear how best to re-write the document in
question to not duplicate these otherwise logical headings.

This reverts commit 10a1df3cd4.

9452d58e10 arm: dart6ul: enable DM_ETH for the dart6ul
This patch converts the dart6ul ethernet support to DM_ETH and cleans
up the legacy ethernet code. The clean up, more specifically:

* moves the fec2 node and pin definition to the carrier board DTS
  since the phy associated with it is on the carrier board and not on
  the SoM;
* add the reset pin associated to each phy;
* separate the ethernet, mdio and reset pins of each fec so that they
  are easier to reference;
* add clock properties to the phy nodes since they are connected to the
  50Mhz ENET[12]_TX_CLK clock of the SoC;
* remove CONFIG_BOARD_EARLY_INIT_F since the function is now empty.

e9624f304d mx6ul(l)evk: Enable DM_ETH_PHY
This fixes eth0 not initializing properly. Both eth0 and eth1 use the
MDIO interface on eth1 to access their PHYs. However, without
DM_ETH_PHY, eth0 still tries to use its own MDIO interface to access its
phy. Before this patch, a boot log might contain lines like

Net:
Warning: ethernet@20b4000 using MAC address from ROM
eth1: ethernet@20b4000 [PRIME]Could not get PHY for FEC0: addr 2

After this patch they now look like

Net:
Warning: ethernet@20b4000 using MAC address from ROM
eth1: ethernet@20b4000 [PRIME]Get shared mii bus on ethernet@2188000

Warning: ethernet@2188000 using MAC address from ROM
, eth0: ethernet@2188000

As an alternative to DM_ETH_PHY, FEC_MXC_SHARE_MDIO could also have been
used to achieve the same effect.

10a394ba68 board: imx8mp: add boot.cmd for distro boot on iMX8MP
Distro Boot requires a U-Boot-specific script named boot.scr or
boot.scr.uimg which contains boot commands to boot the system. The
boot.cmd is such a file. Use mkimage to generate boot.scr or
boot.scr.uimg from boot.cmd, and the command is:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Distro Boot Script" -d boot.cmd boot.scr.uimg

The boot.cmd file is an example script and can be modified based on
needs. bootargs is set in this script and root uses the default value
"/dev/mmcblk1p2 rootwait rw" which can be changed by overriding mmcroot.
