If PM2 is enabled with LPM_CONF_MAX_PM, but not active, the non-retention area of the SRAM can be useful to place temporary data that does not fit in the low-leakage SRAM, typically after having called lpm_set_max_pm(LPM_PM1). Hence, give access to this non-retention area thanks to .nrdata* sections. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>
