Two version are generated. linux.bin.ub which is created from linux.bin file and simpleImage.<dts>.ub which is created from stripped simpleImage.<dts> file Load address and entry point is for microblaze first instruction which is CONFIG_KERNEL_BASE_ADDR variable. There is possible for simpleImage format parse _start symbol too. simpleImage.<dts> is still stripped elf file I cleared simpleImage.<dts>.unstrip file because there are so big.
