> The derating (timing parameter derating using MR4 read value) can't be activated
> during BIST test, as the MR4 read answer will be not understood by BIST
> (BISTGSR.BDONE bit stay at 0, BISTWCSR.DXWCNT = 0x206 instead of
> BISTWCR.BWCNT = 0x200).
> This patch only impacts the tuning on LPDDR2/LPDDR3, if
> derateen.derate_enable = 1.
