Bout perhaps you could add some documentation what all these magic numbers mean? Of course we can all download the documetnation, study it for hours and finally uinderstand this, too - but it would be nicer if you could save us this effort. > > > + u32 reg, pclk_ratio = get_PCLK() / gd->baudrate; > > why not > > u32 reg; > > u32 pclk_ratio = get_PCLK() / gd->baudrate; > > There is more than one way to do it. Indeed. But the one that is better readable is preferred. > > > + /* PCLK / (16 * baudrate) - 1 */ > > > + reg = pclk_ratio / 16 - 1; > > > + i = pclk_ratio - (reg + 1) * 16; > > => > > i = pclk_ratio - (pclk_ratio / 16 - 1 + 1) * 16; > > => > > i = pclk_ratio - (pclk_ratio / 16 ) * 16; > > => > > i = pclk_ratio - pclk_ratio; > > => > > i = 0; > > Please, think again. This is integer arithmetics, not analysis. So perhaps you want to elucidate your code in a comment?
