why so slowly when use serial to download S-record file?

[Kenneth Johansson]

The reason is that ppcboot/u-boot only support a very simple version of
kermit where the sender waits for an ack before sending another block.

kermit should have a mode that is as efficient as some of the
[x|y|z]-modem maybe you could add that code to u-boot.
