From 5079d8bbad77bf21ecc5f17e05141f04cfaaabb3 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 23 Jul 2010 11:34:49 -0400 Subject: Blackfin: jtag-console: robustify against missing peer If the other side isn't listening, we should reset the state to ignore the whole message and not just the part we missed. This makes it easier to connect at any time to the jtag console without worrying about the two sides getting out of sync and thus sending garbage back and forth.

We need custom debug statements because we need the output to only go to the serial port. If we used the standard debug helpers, the output would also go to the stdout (which would be the jtag console) and make it hard to figure out what is going where exactly.

In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation.
