The value for RLE_DEC_AMBA_BASE
is not clear from RM. Can someone confirm its value.

the DMA MUX SOURCE configuration was missed out (vybrid have different source numbers vs rainbow), and that fixed the RLE.
Thanks everyone for this learning opportunity!!
I tried the RLE with DMA destination address to 0x78000080 and DMA source address to 0x780000C0.
I have used a working sample code from Rainbow with MCR.GRLE_EN = 0.
The code doesn't seem to complete the decoding. ISR register has a value of 0x38, which looks like the DMA for reading the tx fifo didn't happen. Let me know if I am missing any configurations?
