[PATCH v6 0/6] Implement fastboot multiresponce

[Svyatoslav Ryhel]

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.
