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 in v5: - restored membuff_readline behavior changed in v4
Changes in v4: - adjust membuff_readline behavior with overflow
Changes in v3: - fix missing function calls if CONFIG_CONSOLE_RECORD is not enabled
Changes in v2: - changed variables to static - fixed multiresponce for udp - documented use of "MORE" - converted #if to if (...) ---
