Currently u-boot fastboot can only send one message back to host, so if there is a need to print more than one line messages must be kept sending until all the required data is obtained. This behavior can be adjusted using multiresponce ability (getting multiple lines of response) proposed in this patch set.
Implementation of multiresponce leads to ability to dump content of console buffer which, with use of "oem run", allows to entirely avoid need in UART.
--- Changes from v1: - changed variables to static - fixed multiresponce for udp - documented use of "MORE" - converted #if to if (...) ---
