Fix NOR, SD and QSPI fallback option in case of secure boot failure.
Signed-off-by: Vinitha V Pillai
Reviewed-by: York Sun -
IFC-NOR and QSPI-NOR pins are multiplexed on SoC, so they cannot be
accessed simultaneously. IFC-NOR can be accessed along with SD-BOOT.Ls1088aqds_sdcard_ifc_defconfig is default config for SD boot and
IFC-NOR to be used as flash. This allows writing to IFC-NOR flash.
QSPI and DSPI cannot be accessed in this defconfig.
IFC-NOR image is generated using ls1088aqds_defconfig.Signed-off-by: Ashish Kumar

This patch makes it possible to verify the contents and location of an
OPTEE image in DRAM prior to handing off control to that image. If image
verification fails we won't try to boot any further.Signed-off-by: Bryan O'Donoghue

This patch adds a new type IH_OS_TEE. This new OS type will be used for
chain-loading to Linux via a TEE.With this patch in-place you can generate a bootable OPTEE image like this:
mkimage -A arm -T kernel -O tee -C none -d tee.bin uTee.optee
where "tee.bin" is the input binary prefixed with an OPTEE header and
uTee.optee is the output prefixed with a u-boot wrapper header.This image type "-T kernel -O tee" is differentiated from the existing
IH_TYPE_TEE "-T tee" in that the IH_TYPE is installed by u-boot (flow
control returns to u-boot) whereas for the new IH_OS_TEE control passes to
the OPTEE firmware and the firmware chainloads onto Linux.Andrew Davis gave the following ASCII diagram:
IH_OS_TEE: (mkimage -T kernel -O tee)

This patch adds optee_verify_bootm_image() which will be subsequently used
to verify the parameters encoded in the OPTEE header match the memory
allocated to the OPTEE region, OPTEE header magic and version prior to

Add a helper function for extracting the least significant 32 bits from the
OPTEE entry point address, which will be good enough to load OPTEE binaries
up to (2^32)-1 bytes.We may need to extend this out later on but for now (2^32)-1 should be
fine.Signed-off-by: Bryan O'Donoghue

CONFIG_OPTEE_LOAD_ADDR is used to tell u-boot where to load the OPTEE
binary into memory prior to handing off control to OPTEE.We need to pull this value out of u-boot in order to produce an IMX IVT/CSF
signed pair for the purposes of secure boot. The best way to do that is to
have CONFIG_OPTEE_LOAD_ADDR appear in u-boot.cfg.Adding new CONFIG entires to u-boot should be kconfig driven so this patch
does just that.Signed-off-by: Bryan O'Donoghue

OPTEE is currently linked to a specific area of memory called the TrustZone
DRAM. This patch adds a CONFIG entry for the default address of TrustZone
DRAM that a board-port can over-ride. The region that U-Boot sets aside for
the OPTEE run-time should be verified before attempting to hand off to the
OPTEE run-time. Each board-port should carefully ensure that the TZDRAM
address specified in the OPTEE build and the TZDRAM address specified in
U-Boot match-up.Further patches will use TZDRAM address with other defines and variables to
carry out a degree of automated verification in U-Boot prior to trying to
boot an OPTEE image.Signed-off-by: Bryan O'Donoghue

This patch adds code to lib to enable sharing of useful OPTEE code between
board-ports and architectures. The code on lib/optee/optee.c comes from the
TI omap2 port. Eventually the OMAP2 code will be patched to include the
shared code. The intention here is to add more useful OPTEE specific code
as more functionality gets added.Signed-off-by: Bryan O'Donoghue
