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.

Commit 56c2dbdabab5 ("imx: bootaux: cleanup code") introduces the
following LTO related warning:
"
arch/arm/mach-imx/imx_bootaux.c:24:31: warning: type of ‘hostmap’ does not match original declaration [-Wlto-type-mismatch]
24 | const __weak struct rproc_att hostmap[] = { };

"
This is because the weak empty array of structures "hostmap" is eventually
replaced by non-empty array of structures with different number of elements.
Fix this by avoiding weak variable size array, instead use a weak function
which returns single pointer to the array.

Originally, the mmc aliases node was present in imx6qdl-sabresd.dtsi.
After the sync with Linux in commit d0399a46e7cd ("imx6dl/imx6qdl:
synchronise device trees with linux"), the aliases node is gone as
the upstream version does not have it.
This causes a regression in which the SD card cannot be found anymore.
Fix it by passing the alias node in the u-boot.dtsi file to
restore the original behaviour where the SD card (esdhc3) was
mapped to mmc1.

The struct dcd_v1_t is initialized to MAX_HW_CFG_SIZE_V1 (60)
structs 'dcd_type_addr_data_t', so the indexes to use on its elements
are [0,59]. But on line 478, the variable 'length' can take on the value
60, which applies to array overflow: cd_v1->addr_data[length].type Thus,
it is necessary to tighten the check on the 'size' variable on line 463.

This reverts commit f5315dd6290a588434e4f79bfd2886bb7df9210d.
[why]
TPL is not mandatory for not all Rockchip SoCs, some SoCs like
RK356x, and RK3588 still use mainline u-boot without TPL as
their ddr init programs are accessed via binaries provided by
Rockchip instead of ddr source code.
Marking TPL build makes it not able to build u-boot.itb on
RK356x targets so revert this so that it can build an SPL build
that would support all across Rockchip platforms.

Update the distro config env memory layout for the Apalis iMX8 aka
QuadMax:
- kernel_comp_addr_r=0xf0000000 temporary area for uncompressing (ie FIT
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 fd5c7173ade4
("imx8m{m,n}_venice: update env memory layout"). However, moved past
any reserved areas to avoid any kind of conflicts.
Note that for our regular BSP Layers and Reference Images for Yocto
