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.

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.

restore the original behaviour where the SD card (esdhc3) was
mapped to mmc1.

images or Image.gz booted using booti)
- kernel_comp_size=0x08000000
- loadaddr=0x95400000 avoiding any reserved areas located before that
- fdt_addr_r = loadaddr + 128MB - allows for 128MB kernel
- scriptaddr = fdt_addr_r + 512KB - allows for 512KB fdt
- ramdisk_addr_r = scriptaddr + 512KB - allows for 512KB script
Basic idea of memory layout taken from commit fd5c7173ad
("imx8m{m,n}_venice: update env memory layout"). However, moved past
any reserved areas to avoid any kind of conflicts.
