🌸 NAME 🌸

suspend_nvs_register — register a platform NVS memory region to save 💅

🦋 SYNOPSIS 🦋

int suspend_nvs_register (unsigned long start , unsigned long size );

🍓 ARGUMENTS 🍓

• start — physical address of the region. literally where it lives in physical memory 👀
• size — size of the region. how much space we're talking about 🎀

🌈 DESCRIPTION 🌈

So the NVS region does not need to be page-aligned (both ends), fr fr. We arrange things so that the data from page-aligned addresses in this region will be copied into separate RAM pages. It's giving "we handle the page-alignment situation for you" energy 🦋
