Dear Nikos Mavrogiannopoulos,
In message 49F9738D.9060703@gennetsa.com you wrote:
This patch makes fw_setenv write multiple variables on a single command line. That is "fw_setenv var1 value1 var2 value2" will write all variables and values without the need to erase multiple times the environment.
I reject this as it would introduce serious incompatibilities with the existing interfaces, both in fw_setenv and in the U-Boot setenv command.
Not to mention that it would be extremely error prone.
But I understand that such a functionality may be useful - just your interface design is bogus.
What about the following alternative: add an option to fw_setenv to read the commands (evventually even with an [optional?] leading "setenv") from a file (or from stdin, if no file name or '-' is given). Then you can have one set of parameters per line, and no argument counting or similar things are needed.
What do you think?
Best regards,
Wolfgang Denk
