2847 BCH soft reset may cause bus master lock up.<br />
Description:<br />
The BCH bus master may lock up if <strong>the</strong> soft reset bit (HW_BCH_CTRL_SFTRST) is set.<br />
HW_BCH_CTRL_CLKGATE may be set and cleared as desired to clock gate <strong>the</strong> block, as long<br />
as HW_BCH_CTRL_SFTRST is never set.<br />
Workaround:<br />
Do not assert HW_BCH_CTRL_SFTRST. To reset <strong>the</strong> register set, write desired values to <strong>the</strong> BCH<br />
registers.<br />
