stm32h743xx: Add AXI SRAM memory map

This issue no longer applies and can be closed, IMO. On the Nucleo-H743ZI, I see that AXI ram is mapped (as RAM_D1).

I fail to see how it "no longer applies". main has not moved since I created this.

If you'd like, I can recreate the scenario / the commands I tried to run that do not work without this patch.

On the Nucleo-H743ZI, I see that AXI ram is mapped (as RAM_D1).

Why would on-chip RAM be declared in the board file instead of the MCU target file?

Nah, I can't do anything about this. Just thought I'd mention that I can access ram at 0x24000000 to upload to it.
