77f898d040 x86: Reduce size of samus image
With the recent addition of ACPI generation, the image size has got beyond
its current limit.

Samus does not actually use this, nor x86 emulation for PCI ROMs, so
disable both features.

d85f2c4f29 sandbox: Disable I2C emulators in SPL
These cannot work with of-platdata since they currently need the
devicetree at runtime. Disable the emulators and the sandbox I2C driver
that needs them. We can enable these later, if needed for testing.

Switch the of_plat_parent test over to use a simple bus instead.

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.

64413e1b7c riscv: Add Microchip MPFS Icicle Kit support
This patch adds Microchip MPFS Icicle Kit support. For now, only
NS16550 Serial, Microchip clock, Cadence eMMC and MACB drivers are
enabled. The Microchip MPFS Icicle defconfig by default builds
U-Boot for S-Mode because U-Boot on Microchip PolarFire SoC will run
in S-Mode as payload of HSS + OpenSBI.

8f78e52794 riscv: Add support for SPI on Kendryte K210
This enables configs necessary for using SPI. The environment is saved to
the very end of SPI flash. This is unlikely to be overwritten unless the
entire flash is reprogrammed.

This also supplies a default bootcommand. It loads an image and device tree
from the first partition of the MMC. This is a minimal/least effort
bootcmd, so suggestions (especially in the form of patches) are welcome. I
didn't set up distro boot because I think it is unlikely that any
general-purpose linux distros will ever be ported to this board.
