mtk_eth.c contains not only the ethernet GMAC/DMA driver, but also
some ethernet switch initialization code. As we may add more switch
support in the future, it's better to move them out of mtk_eth.c to
avoid increasing the code complexity.
Since not all switches are supported for a particular board, Kconfig
options are added to allow user to select which switch should be
built into u-boot. If multiple switches are selected, auto-detecting
can also be enabled.

The netc-blk-ctrl driver is used to configure Integrated Endpoint
Register Block (IERB) and Privileged Register Block (PRB) of NETC.
For i.MX platforms, it is also used to configure the NETCMIX block.
The IERB contains registers that are used for pre-boot initialization,
debug, and non-customer configuration. The PRB controls global reset
and global error handling for NETC. The NETCMIX block is mainly used
to set MII protocol and PCS protocol of the links, it also contains
settings for some other functions.
Note the IERB configuration registers can only be written after being
unlocked by PRB, otherwise, all write operations are inhibited. A warm
reset is performed when the IERB is unlocked, and it results in an FLR
to all NETC devices. Therefore, all NETC device drivers must be probed
or initialized after the warm reset is finished.

We are using a custom board where an ethernet switch device KSZ9896 is
available. This family of devices can use several types of serial bus
as management interface: mdio, i2c or SPI. Due to board design
constraints and because we initially planned to use this device only
from Linux, the SPI bus was used.
Luckily we are using a recent enough u-boot release where KSZ9477
driver is available... but only for the i2c interface. Indeed, unlike
the kernel driver, the KSZ9477 driver doesn't use the regmap API to
access the underlying bus since the regmap API is limited to direct
memory access [1].
Until regmap API with bus support is available in U-boot, we introduced
struct ksz_phy_ops to store low-level ksz bus operations (I2C or SPI).
This series has been tested on the current master branch (after v2024.10
release).

The Microchip KSZ Gigabit Ethernet Switches support
SGMII/RGMII/MII/RMII with register access via SPI, I2C, or MDIO.
Since this driver is now able to check the underlying bus type,
handle the case when the SPI bus is used.
The SPI bus is only used for 8/16/32 wide access of registers.
Reword Kconfig option to include SPI bus support.

Some IP cores of dc2114x or its variants do not comply so well with
the behaviors described by the official document. Originally this
driver uses only one tx descriptor and organizes it as a ring buffer,
which would lead to a problem that one packet would be sent twice.
This commit adds support to prevent this bug if you are using IP
cores with this issue, by using multiple tx descriptors and

Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by
adding a new net/lwip/ directory and the NET_LWIP symbol. Network
support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent
commits will introduce the lwIP code, re-work the NETDEVICE integration
and port some of the NET commands and features to lwIP.
SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols
that are part of NET (such as arp_init(), arp_timeout_check(),
arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be
added later.
Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP
because of dependencies on net_loop(), tftp_timeout_ms,
tftp_timeout_count_max and other NET things. Let's add a dependency on
!NET_LWIP for now.
SANDBOX can select NET_LWIP but doing so will currently disable the eth
dm tests as well as the wget tests which have strong dependencies on the
NET code.
Other adjustments to Kconfig files are made to fix "unmet direct
dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when
the default networking stack is set to NET_LWIP ("default NET_LWIP"
instead of "default NET" in Kconfig).
The networking stack is now a choice between NO_NET,
NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be
'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.

Simon Glass <sjg@chromium.org> says:
When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL
Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.
For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:
#if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)
In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.
This series starts a change in terminology and usage to resolve the
above issues:
- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_
It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.
This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.
The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.
SPL_BUILD is not a Kconfig symbol. Perhaps the intent here is to use
SPL instead. However, this causes build errors, e.g. with T1024RDB_NAND
So drop the dependency on !SPL_BUILD since it does nothing.

FTGMAC100 enables drivers/net/ftgmac100.c which uses
PHY_INTERFACE_MODE_NCSI, which is defined only when PHY_NCSI is enabled.
Therefore FTGMAC100 depends on PHY_NCSI. However adding such a
dependency causes a "recursive dependency detected!" message, so
add a dependency on NET instead (PHY_NCSI depends on NET).
All in all, either the stack is NET and FTGMAC100 can be enabled,
or it is NET_LWIP (or NO_NET) and it cannot.
