Hey, I'm having some trouble with my linker script.

There's a little section here about extra sections: https://docs.rs/cortex-m-rt/latest/cortex_m_rt/#extra-sections

I too have an extra section, but the way it's specified in the link, any data in the section isn't initialized. However, I do want it to be initialized. How do I do that?

My chip is an STM32H7

```ld
SECTIONS {
    .axisram : ALIGN(8) {
        *(.axisram .axisram.*);
        . = ALIGN(8);
    } > AXISRAM AT>FLASH

    .uninit_axisram (NOLOAD) : ALIGN(8) {
        *(.uninit_axisram .uninit_axisram.*);
        . = ALIGN(8);
    } > AXISRAM
} INSERT BEFORE .data;
```

From what I'm reading removing the`NOLOAD` and adding the `AT>FLASH` should do it, but it's not loaded. My guess is that the init data is not added to `.data` and `.bss`. What can I do to fix this? Is it even reasonable? Or does `cortex-m-rt` simply not support this?
