As usb_ether driver has no compatible string, it can't be find by
lists_bind_fdt(). In bind_by_node_path(), which called lists_bind_fdt(),
the driver entry is known, pass it to lists_bind_fdt() to force the driver
entry selection.

For this, add a new parameter struct *driver to lists_bind_fdt().

ad7e967738 serial: serial_msm: Delay initialization to let pins stabilize
For some reason, the DragonBoard 410c aborts autoboot immediately if
U-Boot is started without LK. It looks like it picks up a single broken
character via serial and therefore believes a key was pressed to abort
autoboot.

After some debugging, it seems like adding some delay after pinctrl
setup but before UART initialization fixes the issue. It's also worth
mentioning that unlike when booting from LK, the pinctrl setup is
actually necessary when booting U-Boot without LK since UART is broken
if the pinctrl line is removed.

I suspect that reconfiguring the pins might take some time to stabilize
and if the UART controller is enabled too quickly it will pick up some
random noise. Adding a few milliseconds of delay fixes the issue and
shouldn't have any other negative side effects.

3ms seems to be the minimum delay required in my tests, use 5ms instead
just to be sure.

8214728e4f serial: a37xx: Switch to XTAL clock when booting Linux kernel
Unfortunately the UART driver in current Linux for Armada 3700 expects
UART's parent clock to be XTAL and calculats baudrate divisor according
to XTAL clock. Therefore we must switch back to XTAL clock before
booting kernel.

Implement .remove method for this driver with DM_FLAG_OS_PREPARE flag
set.

If current baudrate is unsuitable for XTAL clock then we do not change
anything. This can only happen if the user either configured unsupported
settings or knows what they are doing and has kernel patches which allow
usage of non-XTAL parent clock.

5f41bab86c serial: a37xx: Use TBG as parent clock
Using TBG clock as parent clock for UART allows us using higher

Turris MOX with external FT232RL USB-UART works fine up to 3 MBaud
(which is maximum for this USB-UART controller), while EspressoBIN with
integrated pl2303 USB-UART also works fine up to 6 MBaud.

Slower baudrates with TBG as a parent clock can be achieved by
increasing TBG dividers and oversampling divider. When using the slowest
TBG clock, minimal working baudrate is 300.

139d081384 serial: a37xx: Fix parent clock rate value and divider calculation
UART parent clock is by default the platform's xtal clock, which is
25 MHz.

The value defined in the driver, though, is 25.8048 MHz. This is a hack
for the suboptimal divisor calculation
  Divisor = UART clock / (16 * baudrate)
which does not use rounding division, resulting in a suboptimal value
for divisor if the correct parent clock rate was used.

Change the code for divisor calculation to round to closest value, i.e.
  Divisor = Round(UART clock / (16 * baudrate))
and change the parent clock rate value to that returned by
get_ref_clk().

This makes A3720 UART stable at standard UART baudrates between 1800 and
230400.

725cf89512 serial: serial_msm: Ensure BAM/single character mode are disabled
At the moment, the U-Boot serial_msm driver does not initialize the
UART_DM_DMEN register with the required value. Usually this does not
cause any problems, because there is Qualcomm's LK bootloader running
before U-Boot which initializes the register with the correct value.

It's important that this register is initialized correctly, because
the U-Boot driver does not make use of the BAM/DMA or single character
mode functionality of the UART controller. A different bootloader
before U-Boot might initialize the register differently.

For example, on DragonBoard 410c U-Boot can also be installed to the
"aboot" partition (replacing LK entirely). In this case U-Boot is
loaded directly by SBL, which seems to use the single-character mode
for some reason. In single character mode there is always just one
char in the FIFO, instead of the 4 characters expected by
msm_serial_fetch(). It also causes issues with "earlycon" later in
the Linux kernel, which tries to output 4 chars at once,
but only the first char will be written.

This causes early UART log in Linux to be corrupted like this:

    [ 00ano:ameoi .Q1B[ 00ac _idaM00080oo'ahani-lcle._20). 15NdNii 5 SPMSJ20:U2
    [ 00rkoolmsamel
    [ 00Fw ]elamletopsioble
    [ 00ore

instead of

    [    0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd030]
    [    0.000000] Machine model: Qualcomm Technologies, Inc. APQ 8016 SBC
    [    0.000000] earlycon: msm_serial_dm0 at MMIO 0x00000000078b0000 (options '')
    [    0.000000] printk: bootconsole [msm_serial_dm0] enabled

Make sure to initialize UART_DM_DMEN correctly to fix this issue
when loading U-Boot directly after SBL (instead of through LK).

There is no functional difference when loading U-Boot through LK
since LK also initializes UART_DM_DMEN to 0x0. [1]

e35b6497f4 x86: Make coreboot sysinfo available to any x86 board
It is possible to boot U-Boot for chromebook_coral either 'bare metal' or
from coreboot. In the latter case we want to provide access to the coreboot
sysinfo tables. Move the definitions into a file available to any x86
board.

0b9f1ae586 serial: mtk: rewrite the setbrg function
Currently the setbrg logic of serial-mtk is messy, and should be rewritten.
Also an option is added to make it possible to use highspeed-3 mode for all
bauds.

The new logic is:
1. If baud clock > 12MHz
   a) If baud <= 115200, highspeed-0 mode will be used (ns16550 compatible)
   b) If baud <= 576000, highspeed-2 mode will be used
   c) any bauds > 576000, highspeed-3 mode will be used
2. If baud clock <= 12MHz
   Forced highspeed-3 mode
   a) If baud <= 115200, calculates the divisor using DIV_ROUND_CLOSEST
   b) any bauds > 115200, the same as 1. c)

384b62c073 serial: ns16550: Handle zero <clock-frequency> value
A working device tree node of ns16550 should never be populated
with value zero for the <clock-frequency> property. Unfortunately
this is the case for the QEMU ppce500 target.

Let's try to assign plat->clock to CONFIG_SYS_NS16550_CLK as the
last resort to handle such case.

This commit should be reverted when:

- The following QEMU patch [1] is merged, and
- U-Boot CI has upgraded its QEMU version that contains the fix

09bd08401a serial: ns16550: Correct the base address type
Currently ns16550_serial_assign_base() treats the argument 'base'
with type `ulong`. This is incorrect because the base address was
obtained from device tree with type `fdt_addr_t` that can represent
a physical address larger than 32-bit in a 32-bit system.

7f840c1b26 serial: usbtty: Send urb data in correct order
Function next_urb() selects the last urb data buffer from linked list to
which next data from usbtty's puts function should be appended.

But to check if TX data still exists it is needed to look at the first urb
data buffer from linked list. So check for endpoint->tx_urb (first from the
linked list) instead of current_urb (the last from the linked list).

Successful call to udc_endpoint_write() may invalidate active urb and
allocate new urb in queue which invalidates pointer returned by next_urb()
function.

So call next_urb() prior putting data into urb buffer and call it every
time after using udc_endpoint_write() function to prevent sending data from
usbtty's puts function in incorrect order.

This patch fixes issue that usbtty code does not transmit data when they
are waiting in the tx queue.

This function has incorrect implementation of prepending CR prior LF.
Without this patch it prepended CR prior whole string which is going to be
written and let LF without leading CR. Fix this issue by inserting CR at
correct place to make output on usbtty serial console more readable.

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.
