I would suggest to move this to you Kconfig file.
something like this:

# The byte offset of the kernel image in RAM from the start of RAM
config UNICORE32_TEXT_OFFSET
hex
default 0x00408000

Then you have the symbol available as CONFIG_UNICORE32_TEXT_OFFSET
both in your Makefiles and in your source files.

And then they use equal methods - OK.
