Early in boot it is necessary to decode the PCI device/function values for
particular peripherals in the device tree or of-platdata. This is needed
in TPL where CONFIG_PCI is not defined.

To handle this, move pci_get_devfn() into a file that is built even when
CONFIG_PCI is not defined.

a pci_dev_t.

This fixes an issue that would cause I2C writes to timeout when the
number of bytes is a multiple of the FIFO depth (i.e. 16 bytes).

Within the transfer loop, after writing the data register with a new
byte to transfer, if the transfer size equals the FIFO depth, the loop
pauses until the INTERRUPT_COMP bit asserts to indicate data has been
sent. This same check is performed after the loop as well to ensure data
has been transferred prior to returning.

In the case where the amount of data to be written is a multiple of the
FIFO depth, the transfer loop would wait for the INTERRUPT_COMP bit to
assert after writing the final byte, and then wait for this bit to
assert once more. However, since the transfer has finished at this
point, no new data has been written to the data register, and hence
INTERRUPT_COMP will never assert.

Fix this by only waiting for INTERRUPT_COMP in the transfer loop if
there's still data to be written.

riscv: increase stack size to avoid a stack overflow during distro boot

This fixes a problem, where booting Linux using distro boot will
sometimes lead to an invalid instruction exception on the main hart. The
secondary harts are not affected and boot Linux successfully. The root
cause of this problem is a stack overflow on the main hart.

With distro boot, the current default stack size of 8KiB on RISC-V is
not sufficient and will cause a stack overflow. The stacks are allocated
sequentially. In the case of a stack overflow the stack of the main hart
can reach into that of another hart and be corrupted.

The stack overflow previously did not cause any problems, because only
stack frames, which are not used anymore since the hart enters Linux,
were corrupted. Starting with GCC 9, the stack usage has decreased. Now,
only the most recent stack frame overflows into the stack of a secondary
hart and is corrupted. The illegal instruction exception is caused by
the secondary hart overwriting the return address in the stack frame of
the main hart with an address that does not include valid code.

Increase the default stack size of each hart to 16KiB to avoid this
problem.

net: phy: dp83867: rework delay rgmii delay handling

Based on commit c11669a2757e ("net: phy: dp83867: Rework delay rgmii delay
handling") of mainline linux kernel.

The current code is assuming the reset default of the delay control
register was to have delay disabled.  This is what the datasheet shows as
the register's initial value.  However, that's not actually true: the
default is controlled by the PHY's pin strapping.

This patch:
- insures the other direction's delay is disabled If the interface mode is
selected as RX or TX delay only
- validates the delay values and fail if they are not in range
- checks if the board is strapped to have a delay and is configured to use
"rgmii" mode and warning is generated that "rgmii-id" should have been
used.

net: phy: dp83867: Add ability to disable output clock

Based on commit 13c83cf8af0d ("net: phy: dp83867: Add ability to disable
output clock") of mainline linux kernel.

Generally, the output clock pin is only used for testing and only serves as
a source of RF noise after this.  It could be used to daisy-chain PHYs, but
this is uncommon.  Since the PHY can disable the output, make doing so an
option.  I do this by adding another enumeration to the allowed values of
ti,clk-output-sel.

The code was not using the value DP83867_CLK_O_SEL_REF_CLK as one might
expect: to select the REF_CLK as the output.  Rather it meant "keep clock
output setting as is", which, depending on PHY strapping, might not be
outputting REF_CLK.

Change this so DP83867_CLK_O_SEL_REF_CLK means enable REF_CLK output.
Omitting the property will leave the setting as is (which was the previous
behavior in this case).

Out of range values were silently converted into DP83867_CLK_O_SEL_REF_CLK.
Change this so they generate an error.

for disabling clock output") of mainline linux kernel.

The clock output is generally only used for testing and development and not
used to daisy-chain PHYs.  It's just a source of RF noise afterward.

Add a mux value for "off".  I've added it as another enumeration to the
output property.  In the actual PHY, the mux and the output enable are
independently controllable.  However, it doesn't seem useful to be able
to describe the mux setting when the output is disabled.

Document that PHY's default setting will be left as is if the property
is omitted.
