Struct nrf_modem::MemoryLayout

pub struct MemoryLayout {
    pub base_address: u32,
    pub tx_area_size: u32,
    pub rx_area_size: u32,
    pub trace_area_size: u32,
}

The memory layout used by the modem library.

The full range needs to be in the lower 128k of ram. This also contains the fixed nrfxlib_sys::NRF_MODEM_SHMEM_CTRL_SIZE.
