imx8m: Fix MMU table issue for OPTEE memory
When running with OPTEE, the MMU table in u-boot does not remove the OPTEE
memory from its settings. So ARM speculative prefetch in u-boot may access
that OPTEE memory. Due to trust zone is enabled by OPTEE and that memory
is set to secure access, then the speculative prefetch will fail and cause
various memory issue in u-boot.
The fail address register and int_status register in trustzone has logged
that speculative access from u-boot.

ddr: imx8m: fix ddr firmware location when enable SPL OF
With CONFIG_SPL_OF_CONTROL, the device tree will be padded to
end of the u-boot-spl-nodtb.bin, however we also put
the ddr firmware file to this location, so need to adapt
the code with SPL OF and align to 4 bytes to ease copy firmware.

tools: imx8m_image: align spl bin image size
The loader for the DDR firmware in drivers/ddr/imx/imx8m/helper.c uses a
4-byte-aligned address to load the firmware. In cases where OF is
enabled in SPL the dtb will be appended to the SPL binary and can result
in a binary that is not aligned correctly. If OF is not enabled in SPL,
`_end` is already aligned correctly, but this patch does not hurt.
To ensure the correct alignment we use dd to create a temporary file
u-boot-spl-pad.bin with the correct padding.
Since recent splash changes common code for splashscreen logo
should be used instead of adding duplicated code under board
directories. mx6ul_9x9_evk and mx6ul_14x14_evk configurations
used old board specific logo code and do not link, fix them.

The default CSF_SIZE defined in Kconfig is too high and SPL cannot
fit into the OCRAM in certain cases.
The CSF cannot achieve 0x2000 length when using RSA 4K key which is
the largest key size supported by HABv4.
According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices"
it's recommended to pad CSF binary to 0x2000 and append DEK blob to
deploy encrypted boot images.
As the maximum DEK blob size is 0x58 we can reduce CSF_SIZE to 0x2060
which should cover both CSF and DEK blob length.
Update default_image.c and image.c to align with this change and avoid
a U-Boot proper authentication failure in HAB closed devices:
Authenticate image from DDR location 0x877fffc0...

mmc: Replace printf with debug call for timeouts in the i.MX28 mxs driver
This change replaces printf() with debug() for the notification about
commands timeouts.
This is done on purpose (also other drivers use such approach - dw_mmc.c,
mvebu_mmc.c), as the mmc core code (mmc.c) uses timeouts to assess if one
is using sd card or eMMC device.
In such situation timeout is a some kind of a "normal" behavior and there
shall not be any output to the console.
There is no impact on boot time for boards using this driver (even in SPL)
when two extra timeouts are returned (no SD card present, only eMMC
available).
Boot time tested with grabserial:
sudo grabserial -b 115200 -d /dev/ttyUSB1 -e 30 -t -m "^U-Boot SPL*"
spi: fix: Call mxs_reset_block() during DM/DTS probe
Without this change the DM/DTS version of mxs_spi driver doesn't reset the
SPI IP block in probe.
As a result this driver (when used solely on U-Boot proper) relies on reset
performed by mxs spi driver in SPL.
In the use case where eMMC is used in SPL as a boot primary device, the
mxs_reset_block() is not called at all and DM/DTS aware SPI driver in
U-Boot proper is malfunctioning.
dts: imx28: Remove #include "imx28.dtsi" from imx28-u-boot.dtsi file
After this change it is possible to use imx28-<board>-u-boot.dtsi with

imx28-<board>.dts file.
The problem is that the imx28.dtsi included in a wrong place overrides the
changes made in imx28-<board>.dts. As a result some devices are "disabled"
in the final DTB.
imx: Introduce CONFIG_SPL_FORCE_MMC_BOOT to force MMC boot on falcon mode
This change tries to fix the following problem:
- The board boots (to be more precise - ROM loads SPL) from a slow SPI-NOR
memory.
As a result the spl_boot_device() will return SPI-NOR as a boot device
(which is correct).
- The problem is that in 'falcon boot' the eMMC is used as a boot medium to
load kernel from its partition.
Calling spl_boot_device() will break things as it returns SPI-NOR device.
To fix this issue the new CONFIG_SPL_FORCE_MMC_BOOT Kconfig flag is
introduced to handle this special use case. By default it is not defined,
so there is no change in the legacy code flow.
