The first change is to trying to find out TF-A load address based on reading elf file. Expectation is that bl31.bin is in the same folder as bl31.elf. It brings new flexibility to place TF-A to any address (DDR included).
And also enable TEE generation also with TEE configuration. Expecation is the same as above that tee.bin and tee.elf are in the same folder.
User has to just define link to BL31/BL32 binary files and the rest should be handled by the script.

I am using bash that's why not sure if ${BL31%.*} will work on other shells but let's see. --- arch/arm/mach-zynqmp/mkimage_fit_atf.sh | 41 ++++++++++++++++++++++++- 1 file changed, 40 insertions(+), 1 deletion(-)
