I know I can compare a simple value using itest command. e.g.
itest *4000 -eq 1234 && echo 'Addr 4000 contains 1234'
Now my problem is how can I test a bit of 32 bit quantity (say bit 4) stored at location 4000? This is a question about general hush/u-boot shell capability? It is a generic question...
At the moment there is no command that implements this. As you probaly are aware, the "itest" command just implements the following operations:
I did hope there was some clever way to do this using existing commands.
Feel free to add new commands for AND, OR, and XOR...
I will send a patch. I am not sure how OR or XOR could be useful though... We do not support multiple operations or store computed expression results anywhere.
