led and also needs the same cleaning after resume. Data is more complicated, secondary_holding_pen_release is written with the MMU on, clean and invalidated, then read with the MMU off. In contrast __boot_cpu_mode is written with the MMU off, the corresponding cache line is invalidated, so when we read it with the MMU on we don't get stale data. These cache maintenance operations conflict with each other if the values are within a Cache Writeback Granule (CWG) of each other. Collect the data into two sections .mmuoff.data.read and .mmuoff.data.write, the linker script ensures mmuoff.data.write section is aligned to the architectural maximum CWG of 2KB.
