No need to reinvent the wheel. This is what the  logging  driver  was
made  for.  It  handles a ring buffer which is compatible to theLinux
implementation and can be passed directly between kernel and  U-Boot,
i.  e.  you  can  log  messages in U-Boot (like the POST routines are
doing with their test results) and pick them up under Linux,  or  you
can use U-Boot to display the log buffer contents for example after a
Linux kernel crash. See common/cmd_log.c

Note that the Linux kernel must be adapted minimally to pick up  such
a  pre-initialized  log buffer; you can find the modifications in our
kernel tree.

You mean you want syslog over UDP?

There are no such "libraries". You will have  to  build  the  network
packets  manually.  I  recommend  to  implement  such a feature asa n
extension to the existing log buffer driver.

Best regards,
