Browse Source 
- tools/atrf-proxy/PROTOCOL: documented new commands GETRAM and SETRAM
  for SRAM access
- tools/atrf-proxy/atrf-proxy.c (cmd_two, cmd_more): added "setram"
  command
- tools/atrf-proxy/atrf-proxy.c (cmd_more): added "getram" command
- tools/lib/atnet.c (atnet_sram_write, atnet_sram_read): SRAM access
  functions
- tools/lub/atnet.c (atnet_driver): added new functions to driver
  operations
