When CONFIG_DM_ETH is set, the FEC ethernet controller is reset after
the PHY has been set up and initialzed. This breaks the communication
with the PHY and results in an inoperable ethernet interface.
Do the initialization with CONFIG_DM_ETH in the same order as with
legacy ETH support to fix this.

This module can be found on the Turris Omnia board connected
via the I2C interface.
Among some cryptographic functions, the chip has a 512 bit
One Time Programmable memory, 88 byte configuration memory
and 512 byte general purpose memory.
The Turris Omnia stores serial number and device MAC address in
the OTP memory.
This commit adds basic support for reading the EEPROM and also
exposes the chips Random Number Generator.
The driver is based on code by

The Orion watchdog can be found on some Marvell Armada chips.
This driver is based on the code by Tomas Hlavacek in the CZ.NIC
turris-omnia-uboot repository, which can be found at
https://gitlab.labs.nic.cz/turris/turris-omnia-uboot, and that
one is based on code by Sylver Bruneau. His code is already in
mainline Linux kernel.
The code uses the new driver model API.

The DDR3 training code for Marvell A38X currently computes 1t timing
when given board topology map of the Turris Omnia, but Omnia needs 2t.
This patch adds support for enforcing the 2t timing in struct
hws_topology_map, through a new enum hws_timing, which can assume
following values:
HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t
from the number of CSs
HWS_TIM_1T - enforce 1t
HWS_TIM_2T - enforce 2t
This patch also sets all the board topology maps (db-88f6820-amc,
db-88f6820-gp, controlcenterdc and clearfog) to have timing set to
HWS_TIM_DEFAULT.

DTB is encoded in big endian. When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.
We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value. Otherwise sparse warns "cast to restricted __be32".

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing. Follow the naming
of_get_property() from Linux.
The return type (const u32 *) is wrong. DT property values can be

Some AHCI drivers use SCSI under the hood. Rather than making the AHCI
driver be in the SCSI uclass it makes sense to have the AHCI device create
a SCSI device as a child. That way we can handle any AHCI-specific
operations rather than trying to pretend tha the device is just SCSI.
To handle this we need to provide a way for AHCI drivers to bind a SCSI
device as its child, and probe it. Add functions for this.

Two AHCI drivers use SCSI with CONFIG_DM_SCSI. The SCSI uclass calls
scsi_low_level_init() which is implemented by ahci.c. If
CONFIG_SCSI_AHCI_PLAT is defined it does one thing and if it is not
it does something else.
We don't need to call through scsi_low_level_init() to get the init
completed. Instead, adjust the two drivers to call into AHCI directly.
Drop the post-probe init in the SCSI uclass. This means that driver model
doesn't need to use scsi_low_level_init(). It is a legacy function and
driver model should use a driver's probe() method instead.
While we are here, add a comment to the top of the file explaining what
ahci.c does.
