Add a block driver which handles read/write for EFI block devices. This
driver actually already exists ('efi_block') but is not really suitable
for use as a real U-Boot driver:
- The operations do not provide a udevice
- The code is designed for running as part of EFI loader, so uses
EFI_PRINT() and EFI_CALL().
- The bind method probes the device, which is not permitted
- It uses 'EFI' as its parent device
The new driver is more 'normal', just requiring its platform data be set
up in advance.

This fixes two regressions: eMMC operation on boards with WiFi (so using

The sunxi MUSB glue driver has some code to check for external VBUS
presence when it's going to use the MUSB host mode, and it warns if
there is VBUS provided through the cable (in sunxi_musb_enable()).
This code was apparently copied to the USB gadget detection code
(g_dnl_board_usb_cable_connected()), but here we actually *expect*
external VBUS power, so a warning is wrong and confusing.
So far this message rarely triggered, but a recent patch (6fa41cdd19)

The gpio_request_by_name() returns zero in case of success, however the
conditional return value check in gpio_request_by_name() checks only for

This leads to a situation where successful gpio_request_by_name() return
leads to immediate successful eth_phy_of_to_plat() return as well, and
to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the
PHY driver operates with valid reset GPIO, but with assert/deassert times
set to default, which is 0, instead of the values from DT. This breaks
PHY reset.
Fix this by checking if return value is non-zero and then for this one
single allowed non-zero return value, -ENOENT.

Sometimes UART stops transmitting characters after UART clock is changed
back to XTAL. In this state UART fifo is always full. Kernel during early
boot wants to print output on UART and is waiting for non-empty UART fifo.
Which leads to CPU hangup without any (debug) output on UART.
Marvell Armada 3700 Functional Specifications says that for programming
fractional divisor registers it is required to disable UART, enable
loopback mode, reset fifos, program registers, disable loopback mode,
release reset of fifos and enable UART.
But these steps do not fix above mentioned issue that UART hangup. Also
gating UART clock does not help. And even resetting UART state machines do
not help.
Experiments showed that UART fifo is unblocked after board is being reset
(during board reset UART HW transmit UART fifo even CPU is not executing
kernel/bootloader anymore).
And another experiments showed that same workaround can be achieved also
by external reset of UART HW (without need to reset board).
So do not implement any of "Marvell recommended" steps from Functional
Specifications as they do not work. And rather prior changing parent clock
back to XTAL, do external reset of UART HW. This operation also resets all
UART registers, so basically it also sets UART clock to default, which is
XTAL. It is unknown why UART hangups and enters such broken state.

Commit aeb0ca64db ("arm: mvebu: turris_omnia: disable MCU watchdog in
SPL when booting over UART") disabled MCU watchdog when booting over
UART to ensure that watchdog does not reboot the board before UART
transfer finishes.
But if UART transfer fails for some reason, or if U-Boot binary crashes,
then board hangs forever as there is no watchdog running which could
reset it.
To fix this issue, enable A385 watchdog with very high timeout before
disabling MCU watchdog to ensure that even slow transfer can finish
successfully before watchdog timer expires and also to ensure that if
board hangs for some reason, watchdog will reset it.
Omnia's MCU watchdog has fixed 120 seconds timer and it cannot be
changed (without updating MCU firmware). A385 watchdog by default uses
25 MHz input clock and so the largest timeout value (2^32-1) can be
just 171 seconds. But A385 watchdog can be switched to use NBCLK (L2) as
input clock (on Turris Omnia it is 800 MHz clock) and in this case final
watchdog clock frequency is calculated as:
freq = NBCLK / 2 / (2 ^ R)
So A385 watchdog on Turris Omnia can be configured to at most 1374
seconds (about 22 minutes). We set it to 10 minutes, which should be
enough even for bigger U-Boot binaries or slower UART transfers.
Both U-Boot and Linux kernel, when initializing A385 watchdog, switch
watchdog timer to 25 MHz input clock, so usage of NBCLK input clock in
U-Boot SPL does not cause any issues.
