This board has soldered DDR chips. To reduce the SPL image size for
secure boot, use static DDR setting instead of dynamic DDR driver.

+Falcon boot option
+------------------
+Falcon boot is a short cut boot method for SD/eMMC targets. It skips loading the
+RAM version U-Boot. Instead, it loads FIT image and boot directly to Linux.
+CONFIG_SPL_OS_BOOT enables falcon boot. CONFIG_SPL_LOAD_FIT enables the FIT
+image support (also need CONFIG_SPL_OF_LIBFDT, CONFIG_SPL_FIT and optionally
+CONFIG_SPL_GZIP).
+
+To enable falcon boot, a hook function spl_start_uboot() returns 0 to indicate
+booting U-Boot is not the first choice. The kernel FIT image needs to be put
+at CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR. SPL mmc driver reads the header to
+determine if this is a FIT image. If true, FIT image components are parsed and
+copied or decompressed (if applicable) to their desitinations. If FIT image is
+not found, normal U-Boot flow will follow.
+
+An important part of falcon boot is to prepare the device tree. A normal U-Boot
+does FDT fixups when booting Linux. For falcon boot, Linux boots directly from
+SPL, skipping the normal U-Boot. The device tree has to be prepared in advance.
+A command "spl export" should be called under the normal RAM version U-Boot.
+It is equivalent to go through "bootm" step-by-step until device tree fixup is
+done. The device tree in memory is the one needed for falcon boot. Falcon boot
+flow suggests to save this image to SD/eMMC at the location pointed by macro
+CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR, with maximum size specified by macro
+CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTORS. However, when FIT image is used for
+Linux, the device tree stored in FIT image overwrites the memory loaded by spl
+driver from these sectors. We could change this loading order to favor the
+stored sectors. But when secure boot is enabled, these sectors are used for
+signature header and needs to be loaded before the FIT image. So it is important
+to understand the device tree in FIT image should be the one actually used, or
+leave it abscent to favor the stored sectors. It is easier to deploy the FIT
+image with embedded static device tree to multiple boards.
+
+Macro CONFIG_SYS_SPL_ARGS_ADDR serves two purposes. One is the pointer to load
+the stored sectors to. Normally this is the static device tree. The second
+purpose is the memory location of signature header for secure boot. After the
+FIT image is loaded into memory, it is validated against the signature header
+before individual components are extracted (and optionally decompressed) into
+their final memory locations, respectivelly. After the validation, the header
+is no longer used. The static device tree is copied into this location. So
+this macro is passed as the location of device tree when booting Linux.
+
+Steps to prepare static device tree
+-----------------------------------
+To prepare the static device tree for Layerscape boards, it is important to
+understand the fixups in U-Boot. Memory size and location, as well as reserved
+memory blocks are added/updated. Ethernet MAC addressed are updated. FMan
+microcode (if used) is embedded in the device tree. Kernel command line and
+initrd information are embedded. Others including CPU status, boot method,
+Ethernet port status, etc. are also updated.
+
+Following normal booting process, all variables are set, all images are loaded
+before "bootm" command would be issued to boot, run command
+
+spl export fdt <address>
+
+where the address is the location of FIT image. U-Boot goes through the booting
+process as if "bootm start", "bootm loados", "bootm ramdisk"... commands but
+stops before "bootm go". There we have the fixed-up device tree in memory.
+We can check the device tree header by these commands
+
+fdt addr <fdt address>
+fdt header
+
+Where the fdt address is the device tree in memory. It is printed by U-Boot.
+It is useful to know the exact size. One way to extract this static device
+tree is to save it to eMMC/SD using command in U-Boot, and extract under Linux
+with these commands, repectivelly
+
+mmc write <address> <sector> <sectors>
+dd if=/dev/mmcblk0 of=<filename> bs=512 skip=<sector> count=<sectors>
+
+Note, U-Boot takes values as hexadecimals while Linux takes them as decimals by
+default. If using NAND or other storage, the commands are slightly different.
+When we have the static device tree image, we can re-make the FIT image with
+it. It is important to specify the load addresses in FIT image for every
+components. Otherwise U-Boot cannot load them correctly.
+
+Other things to consider
+-----------------------
+Falcon boot skips a lot of initialization in U-Boot. If Linux expects the
+hardware to be initialized by U-Boot, the related code should be ported to SPL
+build. For example, if Linux expect Ethernet PHY to be initialized in U-Boot
+(which is not a common case), the PHY initialization has to be included in
+falcon boot. This increases the SPL image size and should be handled carefully.
+If Linux has PHY driver enabled, it still depends on the correct MDIO bus setup
+in U-Boot. Normal U-Boot sets the MDC ratio to generate a proper clock signal.

Update defconfig to enable falcon boot, add needed macros to board
header file. Because environment variables are not avaiable during
SPL stage for SD boot, set "boot_os=y" as default.

When U-Boot runs at EL2 on ARMv8, OCRAM is in secure world on some
SoCs by default. Allocation of memory from OCRAM causes failure in
this case. Since main memory is available, allocating memory
from heap is successful.

Looking at the contents of this file here, can you please do a follow-up
to move pretty much most of this content to
include/environment/fsl/chain_of_trust.h (or whatever name you thinks
makes most sense) ? Thanks!

Enable falcon boot for SD secure boot. Align non-secure boot image
to sector 0x110 to unify flash layout. Align ARGS sectors with normal
secure boot layout as well. With these changes, both falcon boot and
normal secure boot use the same sectors for FIT image header.
