Update the ftgmac100 driver to support NC-SI instead of an mdio phy
where available. This is a common setup for Aspeed AST2x00 platforms.
NC-SI mode is determined from the device-tree if either phy-mode sets it
or the use-ncsi property exists. If set then normal mdio setup is
skipped in favour of the NC-SI phy.

For the TI SoCs affected by errata i2329, enable MDIO manual

Signed-off-by: Ravi Gunasekaran <r-gunasekaran@ti.com>
Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
In certain TI SoCs, on the CPSW and ICSS peripherals, there is
a possibility that the MDIO interface returns corrupt data on
MDIO reads or writes incorrect data on MDIO writes. There is also
a possibility for the MDIO interface to become unavailable until
the next peripheral reset.
The workaround is to configure the MDIO in manual mode and disable the
MDIO state machine and emulate the MDIO protocol by reading and writing
appropriate fields in MDIO_MANUAL_IF_REG register of the MDIO controller
to manipulate the MDIO clock and data pins.
More details about the errata i2329 and the workaround is available in:
https://www.ti.com/lit/er/sprz487a/sprz487a.pdf
Add implementation to disable MDIO state machine, configure MDIO in manual

Function ioremap_nocache seems to be defined only for MIPS and Microblaze
architectures. Therefore, the function call in the emaclite driver causes
this driver to be unusable with other architectures, for example RISC-V.
Use ioremap function instead of ioremap_nocache, and include linux/io.h
instead of asm/io.h, so that ioremap function is automatically created,
if not defined by the architecture. We can switch to the ioremap function,
as Microblaze's ioremap_nocache is just empty and in MIPS implementations
of ioremap_nocache and ioremap are the same.

Fman microcode is executable code (AFAICT) loaded into a
coprocessor. As such, if verified boot is enabled, it must be verified
like other executable code. However, this is not currently done.
This commit adds verified boot functionality by encapsulating the
microcode in a FIT, which can then be signed/verified as normal. By
default we allow fallback to unencapsulated firmware, but if
CONFIG_FIT_SIGNATURE is enabled, then we make it mandatory. Because
existing Layerscape do not use this config (instead enabling
CONFIG_CHAIN_OF_TRUST), this should not break any existing boards.
An example (mildly-abbreviated) its is provided below:
/ {
#address-cells = <1>;
images {
firmware {
data = /incbin/(/path/to/firmware);
type = "firmware";
arch = "arm64";
compression = "none";
signature {
algo = "sha256,rsa2048";
key-name-hint = "your key name";
};
};

Only two boards in the tree set the macro DWC_NET_PHYADDR. Both have
CONFIG_DM_ETH_PHY=y, so should set the phy address in DT if necessary.
The imx8mp_evk does set the correct address in device tree.
The other board seems to be a copy-paste-adapt from an old
version of the imx8mp_evk config header, given the "#ifdef
CONFIG_DWC_ETH_QOS" block that has been removed from imx8mp_evk header
in commit 127fb45495. Its device tree doesn't even enable (i.e., set
'status = "okay"') the &eqos node. But the other ethernet device,
&fec, does get enabled, and does have a phy sitting at address 4 (and
it also has a corresponding legacy #define CONFIG_FEC_MXC_PHYADDR
4). So I believe it should be completely safe to remove it from there
as well.

since a longer time. Adding it to U-Boot now, enables the boards which
describe the register settings in their DT files here as well.
I've included calling this marvell_of_reg_init() to all foo_config()
functions in this patch as well. If CONFIG_DM_ETH is not set, there is
no ofnode, or no "marvell,reg-init" property, the PHY initialization is
unchanged.
The function marvell_of_reg_init() is a port of the Linux version.
Please note that I explicitly did not add error checking and handling
to the U-Boot version, as this is basically not done for phy_read/write
