Now that PCI Bridge (PCIe Root Port) for Aardvark is emulated in U-Boot,
add support for handling and propagation of CRSSVE bit.
When CRSSVE bit is unset (default), driver has to reissue config
read/write request on CRS response.
CRSSVE bit is supported only when CRSVIS bit is provided in read-only
Root Capabilities register. So manually inject this CRSVIS bit into read
response for that register.

Now that PCI Bridge is working for the PCIe Root Port, U-Boot's PCI_PNP

Aardvark does not have a real PCIe Root Port device on the root bus.
Instead it has PCIe registers of PCIe Root Port device mapped in
internal Aardvark memory space starting at offset 0xc0.
The PCIe Root Port itself is normally available as a PCI Bridge device
on the root bus with bus number zero. Aardvark instead has the
configuration registers of this PCI Bridge at offset 0x00 of Aardvark's
memory space, but the class code of this device is Mass Storage
Controller (0x010400), instead of PCI Bridge (0x600400), which causes
U-Boot to fail to recognize it as a P2P Bridge
Add a hook into the pcie_advk_read_config() / pcie_advk_write_config()
functions to redirect access for root bus from PIO transfer to this
internal Aardvark memory space. This will allow U-Boot to access
configuration space of this PCI Bridge which represents PCIe Root Port.
Redirect access to PCI Bridge registers in range 0x10 - 0x34 to driver's
internal buffer (cfgcache[]). This is because at those addresses
Aardvark has different registers, incompatible with config space of a
PCI Bridge.
Redirect access to PCI Bridge register PCI_ROM_ADDRESS1 (0x38) to
Aardvark internal address for that register (0x30).
When reading PCI Bridge register PCI_HEADER_TYPE, set it explicitly to
value Type 1 (PCI_HEADER_TYPE_BRIDGE) as PCI Bridge must be of Type 1.
When writing to PCI_PRIMARY_BUS or PCI_SECONDARY_BUS registers on this
PCI Bridge, correctly update driver's first_busno and sec_busno
variables, so that pcie_advk_addr_valid() function can check if address
of any device behind the root bus is valid and that PIO transfers are
started with correct config type (1 vs 0), which is required for
accessing devices behind some PCI bridge after the root bus.
U-Boot's PCI_PNP code sets primary and secondary bus numbers as relative
to the configured bus number of the root bus. This is done so that
U-Boot can support multiple PCIe host bridges or multiple root port
buses, when internal bus numbers are different.
Now that root bus is available, update code in pcie_advk_read_config()
and pcie_advk_write_config() functions to correctly calculate real
Aardvark bus number of the target device from U-Boot's bus number as:
busno = PCI_BUS(bdf) - dev_seq(bus)

nand_dt_init() is still using fdtdec_xx() interface.
If OF_LIVE flag is enabled, dt property can't be get anymore.
Updating all fdtdec_xx() interface to ofnode_xx() to solve this issue.
For doing this, node parameter type must be ofnode.
First idea was to convert "node" parameter to ofnode type inside
nand_dt_init() using offset_to_ofnode(node). But offset_to_ofnode()
is not bijective, in case OF_LIVE flag is enabled, it performs an assert().
So, this leads to update nand_chip struct flash_node field from int to
ofnode and to update all nand_dt_init() callers.

Before e2e95e5e25 ("spi: Update speed/mode on change") most systems
silently defaulted to SF bus mode 0. Now the mode is always updated,
which causes breakage. It seems most SF which are used as boot media
operate in bus mode 0, so switch that as the default.
This should fix booting at least on Altera SoCFPGA, ST STM32, Xilinx

with mode 3. Marvell Kirkwood and Xilinx microblaze need to be checked

Force the mtd name of spi-nor to "nor" + the driver sequence number:
"nor0", "nor1"... beginning after the existing nor devices.
This patch is coherent with existing "nand" and "spi-nand"
mtd device names.
When CFI MTD NOR device are supported, the spi-nor index is chosen after
the last CFI device defined by CONFIG_SYS_MAX_FLASH_BANKS.
When CONFIG_SYS_MAX_FLASH_BANKS_DETECT is activated, this config
is replaced by to cfi_flash_num_flash_banks in the include file
mtd/cfi_flash.h.
This generic name "nor%d" can be use to identify the mtd spi-nor device
without knowing the real device name or the DT path of the device,
used with API get_mtd_device_nm() and is used in mtdparts command.
This patch also avoids issue when the same NOR device is present 2 times,
for example on STM32MP15F-EV1:

which resulted in this patch:
https://patchwork.kernel.org/project/netdevbpf/patch/20210704134325.24842-1-pali@kernel.org/

https://patchwork.kernel.org/project/linux-arm-kernel/patch/1512016235-15909-1-git-send-email-Bhaskar.Upadhaya@nxp.com/
it became apparent that nobody really knows what "SGMII 2500" is.
Certainly, Freescale/NXP hardware engineers name this protocol
"SGMII 2500" in the reference manuals, but the PCS devices do not
support any "SGMII" specific features when operating at the speed of
2500 Mbps, no in-band autoneg and no speed change via symbol replication
. So that leaves a fixed speed of 2500 Mbps using a coding of 8b/10b
with a SERDES lane frequency of 3.125 GHz. In fact, "SGMII 2500 without
in-band autoneg and at a fixed speed" is indistinguishable from
"2500base-x without in-band autoneg", which is precisely what these NXP
devices support.
So it just appears that "SGMII 2500" is an unclear name with no clear
definition that stuck.
As such, in the Linux kernel, the drivers which use this SERDES protocol
use the 2500base-x phy-mode.
This patch converts U-Boot to use 2500base-x too, or at least, as much
as it can.
Note that I would have really liked to delete PHY_INTERFACE_MODE_SGMII_2500
completely, but the mvpp2 driver seems to even distinguish between SGMII
2500 and 2500base-X. Namely, it enables in-band autoneg for one but not
the other, and forces flow control for one but not the other. This goes
back to the idea that maybe 2500base-X is a fiber protocol and SGMII-2500
is an MII protocol (connects a MAC to a PHY such as Aquantia), but the
two are practically indistinguishable through everything except use case.
NXP devices can support both use cases through an identical configuration,
for example RX flow control can be unconditionally enabled in order to
support rate adaptation performed by an Aquantia PHY. At least I can
find no indication in online documents published by Cisco which would
point towards "SGMII-2500" being an actual standard with an actual
definition, so I cannot say "yes, NXP devices support it".

It is an unfortunate reality that some PHY settings done by U-Boot
persist even after the PHY is reset and taken over by Linux, and even
more unfortunate that Linux has come to depend on things being set in a
certain way.
For example, on the NXP LS1028A-RDB, the felix switch ports are
connected to a VSC8514 QSGMII PHY. Between the switch port PCS and the
PHY, the U-Boot drivers enable in-band auto-negotiation which makes the
copper-side negotiated speed and duplex be transmitted from the PHY to
the MAC automatically.
The PHY driver portion that does this is in vsc8514_config():
/* Enable Serdes Auto-negotiation */
phy_write(phydev, MDIO_DEVAD_NONE, PHY_EXT_PAGE_ACCESS,
PHY_EXT_PAGE_ACCESS_EXTENDED3);
val = phy_read(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON);
val = val | MIIM_VSC8574_MAC_SERDES_ANEG;
phy_write(phydev, MDIO_DEVAD_NONE, MIIM_VSC8514_MAC_SERDES_CON, val);
The point is that in-band autoneg should be turned on in both the PHY
and the MAC, or off in both the PHY and the MAC, otherwise the QSGMII
link will be broken.
And because phy_config() is currently called at .port_enable() time, the
result is that ports on which traffic has been sent in U-Boot will have
in-band autoneg enabled, and the rest won't.
It can be argued that the Linux kernel should not assume one way or
another and just reinitialize everything according to what it expects,
and that is completely fair. In fact, I've already started an attempt to
remove this dependency, although admittedly I am making slow progress at
it:
https://patchwork.kernel.org/project/netdevbpf/cover/20210212172341.3489046-1-olteanv@gmail.com/
Nonetheless, the sad reality is that NXP also has, apart from kernel
drivers, some user space networking (DPDK), and for some reason, the
expectation there is that somebody else initializes the PHYs. The kernel
can't do it because the device ownership doesn't belong to the kernel,
so what remains is for the bootloader to do it (especially since other
drivers generally call phy_config() at probe time). This is a really
weak guarantee that might break at any time, but apparently that is
enough for some.
Since initializing the ports and PHYs at probe time does not break
anything, we can just do that.
