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.

The EC can store small amounts of data for the benefit of the
verified boot process. Since the EC is seldom reset, this can allow the
AP to store data that survives a reboot or a suspend/resume cycle.
Add support for this.

When the Cr50 starts up it doesn't have a valid locality. The driver sets
it to -1 to indicate that. Tracking this allows cr50_i2c_cleanup() to
avoid releasing a locality that was not claimed.
However the helper functions that generate the flags use a u8 type which
cannot support -1, so they return a locality of 0xff.
Fix this by updating the type. With this, 'tpm startup TPM2_SU_CLEAR'
works as expected.

This patch adds support for MTK SPI NOR controller, which you
can see on mt7622 & mt7629.
1. This controller is designed only for SPI NOR. We can't adjust
its bus clock dynamically. Set clock in dts instead.
2. This controller only supports 1-1-1 write mode.
3. Remove mtk_snor_match_read() since upper SPI-MEM layer already
handles command.
4. sf read/write/update commands are tested with this driver.

This patch completely removes CONFIG_PCI_ENUM_ONLY from the PCI code as
it is not configured for any board (any more). With this removal, some

Additional, dm_pciauto_setup_device() is now static, as it's not

The phydev structure has a PHY OF node pointer in it, use that OF node
first when looking up PHY OF node properties, since that is likely the
correct PHY OF node pointer. If the pointer is not valid, which is the
case e.g. on legacy DTs, fall back to parsing MAC ethernet-phy subnode.

Using (dm_)pci_virt_to_mem() is incorrect to translate the virtual
address in local DRAM to a physical address. The correct macro here
is virt_to_phys() so switch to using this macro.
As virt_to_bus() is now not used any more, this patch also removes
both definitions (DM and non-DM).

On my DS414, some PCI devices return odd values when probing BAR sizes.
An obvious case is all-ones response, the Linux driver
(drivers/pci/probe.c) catches those explicitly and a comment explains
that either bit 0 or bit 1 must be clear (depending on MEM or IO type).
Other BARs return e.g. 0xfff0000f or 0xfff00004 and thus manage to break
size calculation due to the "middle" zeroes. Mitigate that copying more
or less what Linux does and do a "find least bit set".

is removed from U-Boot DM and corresponding slot is disabled. Therefore on
Espressobin board without soldered emmc, state of emmc hw should be same as

The Armada driver also works on Nedap's custom Kirkwood board with a
Marvell 88F6180 CPU. The original commit of that driver,
commit 704d9a645e17 ("gpio: Add DM GPIO driver for Marvell MVEBU"),
also mentions that this driver would be suitable for Kirkwood. This
does not completely replace the Kirkwood specific driver as there
are still boards depending on that driver.

So far the only difference between the various Allwinner MMC controller
we are concerned about is the mod clock register offset.
This is actually not directly related to the MMC controller IP, but an
integration choice, dependent on the SoC this appears in.
To avoid becoming trapped with some compatible fallback strings, let's
remove the whole struct sunxi_mmc_variant, and replace this with a SoC
based choice, which we can derive from the CONFIG_MACH_SUNx_y symbols.
This will later simplify H616 support.

So far all GBit users of the sun8i-emac driver were using the "rgmii"
PHY mode, even though this turns out to be wrong. It just worked because
the PHY driver doesn't do the proper setup (yet).
In fact for most boards the "rgmii-id" or "rgmii-txid" PHY modes are the
correct ones.
To allow the DTs to describe the phy-mode correctly, and to stay
compatible with Linux, at least allow those other RGMII modes in the
driver.
This avoids breakage if mainline DTs will be synced with U-Boot.
