34694f1a3e ARM: imx8mm: verdin-imx8mm: Rework board_early_init()
Rename board_early_init_f() to board_early_init(), since this function
has nothing to do with actual board_early_init_f() as used throughout
U-Boot. The board_early_init() is function local to this board used to
configure UART and WDT pinmux. Wrap init_uart_clk() into this function
so that early UART init would be all in one place. Turn the function
into __weak one, so it could be overridden in case custom carrier board
uses different UART or needs custom IOMUX settings.

1c9bc0fffa imx8m: soc: Relocate u-boot to the top DDR in 4GB space
The EFI memory init uses gd->ram_top for conventional memory. In
current implementation, the ram_top is below optee address. This cause
grub failed to allocation memory for initrd.
The change updates DDR bank setup functions to place the u-boot at top
DDR in 4GB space.

aa42894471 mx6: ddr: Wait before issuing the first MRS cmd
Wait 1ms before issuing the first MRS command to write DDR3 Mode
registers.

There is a requirement to wait a minimum time before issuing command to
the DDR3 device, according to the JEDEC standard this time is 500us
(after RESET_n is de-asserted until CKE becomes active) + tXPR (Reset
CKE Exit time, maximum value 360ns).

It seems that for some reason this is not enforced by the MMDC
controller.

Without this change we experienced random memory initialization failures
with about 2% boot failure rate on specific problematic boards, after
this change we were able to do more than 10.000 power-cycle without a
single failure.

09dbac8174 mx6: ddr: Restore ralat/walat in write level calibration
The current DDR write level calibration routine always overwrite
the ralat/walat fields to their maximum value, just save
the existing values at the beginning of the calibration routine
and restore it at the end.

In case the delay is estimated by the user to be more than one cycle the
walat should be configured according to that, this is not
automatically done.  From the i.MX6 RM:

   The user should read the results of the associated delay-line at
   MPWLDECTRL#[WL_DL_ABS_OFFSET#] and in case the user estimates that the
   reasonable delay may be above 1 cycle then the user should indicate it at
   MPWLDECTRL#[WL_CYC_DEL#]. Moreover the user should indicate it in
   MDMISC[WALAT] field. For example, if the result of the write leveling calibration
   is 100/256 parts of a cycle, but the user estimates that the delay is above 2 cycles
   then MPWLDECTRL#[WL_CYC_DEL#] should be configured to 2, so the total
   delay will be 2 and 100/256 parts of a cycle

Probably it would just possible to not overwrite the mdmisc register in
the first place, since this is not present in the write_level_calib() example
in NXP AN4467 nor in the i.MX6 RM (44.11.6.1 Hardware Write Leveling
Calibration).

The mxs_nand_spl driver can support to read from page unaligned offset,
so don't need to set bl_len to ask spl_load_simple_fit to handle
the page unaligned access.

Actually spl_load_simple_fit has two parts of reading:
spl_simple_fit_read and spl_load_fit_image.
The spl_load_fit_image can handle the page unaligned offset,
but the spl_simple_fit_read can't do it. spl_simple_fit_read requires
the FIT location at page aligned offset.

Hence, remove the nand_get_mtd overwrite function from mxs_nand_spl
to use page unaligned read by driver.
