1434f93ee0 arm: imx: imx8m: Map RAM as NS if PSCI provider
In case U-Boot is a PSCI provider, map RAM explicitly as NS,
otherwise secondary cores crash with SError when attempting
to access RAM mapped as secure in EL2.

0b32bc4831 imx6q-sabrelite: Re-add mmc aliases
In commit d0399a46e7, the device tree was
synchronized from linux and the aliases were dropped.

They need to be kept so that the mmc cards are in the right order.
Without the aliases, u-boot reports:
MMC:   FSL_SDHC: 2, FSL_SDHC: 3

With the aliases, u-boot reports:
MMC:   FSL_SDHC: 0, FSL_SDHC: 1

The upstream linux device tree does not contain the same aliases than
u-boot (It keeps the devices order with /dev/mmcblk2 and /dev/mmcblk3).
Because this board has been using different aliases in u-boot
and linux, a imx6q-sabrelite-u-boot.dtsi file is added to be
automatically included in imx6q-sabrelite.dts.

This way, linux and u-boot each keep their own aliases and there
is no breakage on current installations.

This should never be done for new boards as we want to keep linux and
u-boot with the same aliases as much as possible.
This patch is only necessary to avoid breaking existing setups.

747c2e613b imx: imx6ul: kontron-sl-mx6ul: Disable CONFIG_FSL_QSPI_AHB_FULL_MAP to fix SPI NAND read access
The introduction of CONFIG_FSL_QSPI_AHB_FULL_MAP as default in:

def88bce09 ("spi: fsl_qspi: Support to use full AHB space on i.MX")

broke the SPI NAND read access on the Kontron SL i.MX6UL/ULL boards.
Reading data from the flash returns garbage instead of the actual
content. Fix this for now by disabling the introduced option.

In the long run this should be fixed globally.

7150f56a85 serial: mxc: Wait for TX completion before reset
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).

c4d79448b0 mx7: clock: Use 60MHz for the I2C clocks
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.
