CCS/MSP430FR5989: Referencing Memory Section start address and length from linker file

Tool/software: Code Composer Studio

Hey all,

I am trying to figure out the best way that I can reference in code the start address and length of a memory section defined in the linker file. 

I have found a way to do this, but it seems a little hacky and I was wondering if there is a cleaner way to do it.

As an example, I would have the following in my linker file:

#define TEST_ADDRESS_LOC				0x15000
#define TEST_ADDRESS_LEN				0x1000

TEST_ADDRESS							= TEST_ADDRESS_LOC;

MEMORY
{
    TEST_SECTION: origin = TEST_ADDRESS_LOC, length = TEST_ADDRESS_LEN
}

SECTIONS
{
   .testSection		: {} > TEST_SECTION type=NOINIT
}

and then in code I would define 

extern volatile unsigned long TEST_ADDRESS;

and use TEST_ADDRESS as my origin pointer (very similar to how the compiler maps the register addresses).

While this gets the job done, is there a cleaner way to do this where I don't have to use the variables (where i can just access the sections start address and length without having to define it in two places in the linker file), or is there a way I can assign the value of TEST_ADDRESS to the origin of TEST_SECTION?
