+target programming performance as IO and target programming can easily be profiled

+@chapter TFTP
+@cindex TFTP
+If OpenOCD runs on an embedded host(as ZY1000 does), then tftp can
+be used to access files on PCs(either developer PC or some other PC).
+
+The way this works is to prefix a filename by "/tftp/ip/" and append
+the tftp path on the tftp server(tftpd). E.g. "load_image /tftp/10.0.0.96/c:\temp\abc.elf"
+will load c:\temp\abc.elf from the developer pc (10.0.0.96) into memory as
+if the file was hosted on the embedded host.
+
+In order to achieve decent performance, you must choose a tftp server
+that supports a packet size bigger than the default packet size(512 bytes). There
+are numerous tftp servers out there(free and commercial) and you will have to do
+a bit of googling to find something that fits your requirements.

is the low level API upon which "flash banks" is implemented.

OpenOCD commands can consist of two words, e.g. "flash banks". The
startup.tcl "unknown" proc will translate this into a tcl proc
called "flash_banks".
