The u-boot console may show some corrupted characters when
printing in board_init() due to reset or baudrate change
of the UART (probe) before the TX FIFO has been completely
drained.
To fix this issue, and in case UART is still running, we now
try to flush the FIFO before proceeding to UART reinitialization.
For this we're waiting for Transmitter Complete bit, indicating
that the FIFO and the shift register are empty.
flushing has a 4ms timeout guard, which is normally more than
enough to consume the FIFO @ low baudrate (9600bps).

When an I2C clock is enabled inside enable_i2c_clk() the clock rate is
configured as PLL_SYS_MAIN_120M_CLK / 2 = 60MHz.
Currently, the I2C clock is retrieved from I2C1_CLK_ROOT, which
may not be the one that was enabled.
As there is no clock driver for the imx7d, it is better to return 60MHz
for the I2C clock.
This provides a workaround for the imx7d-pico board, where I2C4 is
connected to the PMIC.
With this change, it is possible to convert the imx7d-pico board
to DM_I2C and DM_PMIC.

After the sync with Linux in commit d0399a46e7 ("imx6dl/imx6qdl:

the upstream version does not have it.
This causes a regression in which the SD card cannot be found anymore.

- kernel_comp_size=0x08000000

First, to quote the author:
This series adds support for the PCIe controller found on Apple M1 and
M2 machines and enables support for PCIe XHCI controllers. This makes
the type-A USB ports on the M1 Mac mini work. Since the use of Apples
DART IOMMU is mandatory (these PCIe DARTs don't support bypass mode),
this adds DMA mapping operations to the IOMMU uclass and implements
them for the Apple DART. It modifies the XHCI driver code to go map
DMA buffers through the IOMMU if there is one. Since the M1 Mac mini
now has two types of XHCI controllers with different number of ports
(2 for the DWC3 controllers, 8 for the Fresco Logic PCIe controller)
this uncovered an issue in with the way the hub descriptor is
implemented in the XHCI driver.
Second, Mark also fixes some Apple-specific instances of
CONFIG_IS_ENABLED that should be IS_ENABLED.
