The current dc21x4x driver accesses its memory mapped registers directly
instead of using the standard I/O accessors. This can cause problems on
some systems as the accesses can get out of order. So convert the direct
volatile dereferences to use the normal in/out macros.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.

Since the mdio code got upstreamed it is not possible
to activate network ports on CP110 Master and Slave.
The problem is in mvpp2_base_probe which is called for each
CP110 and it initializes the buffer area for descs and rx_buffers.
This should only happen once though and the bd space is actually
set to 0 after the first run of the function.
This leads to an error when the second CP110 tries the initialization
again and disables all network ports on this CP110.
This patch adds a static variable to check if the buffer area is
initialized only once globally.

When compiled as a DM_ETH driver, the scm911x driver was reading the MAC
address from the optional EEPROM storage, but failed to copy this to the
platdata struct. Since it was also missing a definition of the
read_rom_hwaddr() function, the generic Ethernet code was dismissing
this MAC address, falling back to a random address or denying to start
at all.
Add an implementation of .read_rom_hwaddr, and refactor the function
reading the ROM address to be called by all interested parties.
This fixes MAC address issues when using the driver in DM_ETH "mode".

This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.
Before this change it was necessary to use:
/* SPI Flash Configs */
#if defined(CONFIG_SPL_BUILD)
#undef CONFIG_DM_SPI
#undef CONFIG_DM_SPI_FLASH
#undef CONFIG_SPI_FLASH_MTD
#endif
in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.
The goal of this patch:
Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.
Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).
In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):
- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
environment with no fitImage and OF_LIBFDT support).
Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.
This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

As we move towards driver model, it is required to let the FEC driver
know how to properly deal with an Ethernet PHY subnode in the device tree.
For example:
&fec {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_microsom_enet_ar8035>;
phy-handle = <&phy>;
phy-mode = "rgmii-id";
phy-reset-duration = <2>;
phy-reset-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>;
status = "okay";
mdio {
#address-cells = <1>;
#size-cells = <0>;
phy: ethernet-phy@0 {
reg = <0>;
qca,clk-out-frequency = <125000000>;
};
};
};
Currently the PHY node pointer is incorrectly associated with the
Ethernel controller instead of the PHY node itself.
This causes the PHY properties, such as "qca,clk-out-frequency" in
the example above to not get parsed.
Fix this problem by populating the phy_of_node node.

Since two ethernet drivers are independent, we can't ensure their probe

To resolve this problem, introduce an eth phy generic driver and uclass.
After eth-uclass binds, we search the mdio node and binds the phy node
with the eth-phy-generic driver.
When one eth driver get its phy device, the parent of phy device will
probe prior than phy device. So this ensure the eth driver ownes the

Delete the extraneous write to debug reg 5 that enables Tx delay
When the driver was originally introduced in commit "6027384a phylib:
Add Atheros AR8035 GETH PHY support", the Tx delay was being
unconditionally enabled.
Then during "2ec4d10b phy: atheros: add support for RGMII_ID, RGMII_TXID
and RGMII_RXID", the author did not notice that code for enabling Tx
delay code was already. Therefore, the if condition for Tx delay has
always been useless for this PHY since this commit introduced it.
Prior to this patch, every AR8035 PHY in U-boot had Tx delay enabled.
After this patch, only those who define the interface as RGMII_TXID or
RGMII_ID will. This is to be expected, but will nonetheless break the

These accessors are not overridden by any board, and even if they were,
this is something which should be handled via DM now, so remove the
weak alias option. Moreover, drop the inline keyword, as the compiler
can decide better.

Inline all the functions from the header file, as they are not used
outside of the driver or the standalone EEPROM example.
Note that this does introduce considerable amount of duplication in
the standalone EEPROM example, however that one has to be rewritten
anyway, roughly such that the SMC911x driver would expose DM EEPROM
interface and the standalone example would use that.

The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:
"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined
via the license information in the
corresponding source files.
And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.

This hardware reset and reset-wait implementation was twice in the

The DMA may attempt to write a DMA descriptor in the ring while it is
being updated. By writing the DMA descriptor buffer address to 0, it
is assured the DMA will not use such a buffer and the buffer can be
updated without any interference.

This patch prevents an issue where the RX packet might have been
accessed by the CPU, which now has cached data from the packet in
the caches and possibly various write buffers, and these data may
be evicted from the caches into the DRAM while the buffer is also
written by the DMA.
By invalidating the buffer after the CPU accessed it and before the
DMA populates the buffer, it is assured that the buffer will not be
corrupted.

The current code polls the RX desciptor ring for new packets by reading
the RX descriptor status. This works by accident, as the RX descriptors
are often in non-cacheable memory. However, the driver does support use
of RX descriptors in cacheable memory.
This patch adds a missing RX descriptor invalidation, which assures the
CPU will read a fresh copy of the RX descriptor instead of a cached one.

This code programs the next descriptor in the TX descriptor ring into
the hardware as the last valid TX descriptor. The problem is that if
the currenty descriptor is the last one in the array, the code will
not wrap around correctly and use TX descriptor 0 again, but instead
will use TX descriptor at address right past the TX descriptor ring,
which is the first descriptor in the RX ring.
Fix this by adding the necessary wrap-around.

The RX descriptor field 3 should contain only OWN and BUF1V bits before
being used for receiving data by the DMA engine. However, right now, if
the descriptor was already used for receiving data and is being cleared,
the field 3 is only modified and the aforementioned two bits are ORRed
into the field. This could lead to a residual dirty bits being left in
the field 3 from previous transfer, and it generally does. Fully set the
field 3 instead to clear those residual dirty bits.
