TMS320C6747: Concerns about using MRAM with the TMS320C6747

Part Number: TMS320C6747

Hi,
I'm considering using the TMS320C6747 and connecting Everspin MRAM via EMIFA. The specific part number is MR5A16AUMA45.

I'd like to confirm the following:

Q1: Is it possible to use this MRAM as 16-bit asynchronous memory on EMIFA?

Q2: Can RBL boot from this MRAM in EMIFA NOR boot mode?

Q3: Are there any known issues when sharing the EMIFA bus with an FPGA?

Q4: I'll use a separate NOR Flash for booting, but I'll use the MRAM as external work memory connected to EMIFA.

Are there any restrictions or conflicts when using NOR Flash (for boot) and MRAM (for data) simultaneously with different chip selects?

Best Regards,
Keisuke
