Hi, I'd like to send some work upstream that I've made for a Blackfin BF537 based device. The following patch was necessary for a DMA-based high speed UART driver(*) for Blackfin - it allows to start transmission on serial interfaces with more than just one char at a time.
Notes: This already reworked patch obsoletes the one attached to https://www.rtems.org/bugzilla/show_bug.cgi?id=2185 I'm unsure if the amount of bytes to sent, given as an argument to the final call of (*tty->handler.write)(), is properly chosen. It was always fixed to one before. (*)The UART driver itself is not yet ready for upstream, because it lives still in my BSP only and has some specific mechanisms which are not really suited for general use (such as using an extra GPIO for end-of-transfer signalling).
