Re: [U-Boot] [PATCH] command "sspi": add write-only flag '.w' (discard read data)

Hi Mike,

Following the common U-Boot way to do this, I'd suggest sspi [<bus>:]<cs>[.<mode>] <bit_len> <dout> [din_env_var] and either never print the read result to the console (my favorite) or only if no env variable to store is passed. To be defined, comments welcome.

is this the common u-boot approach ? seems like extending every random func to take a supplementary env var is the wrong way. if the hush shell simply supported syntax like: foo="`sspi ......`" then every command would get this for free

Indeed - this would be the best solution and I would greatly appreciate such a feature as it would be a big step in what we can script (elegantly) in U-Boot.

Cheers Detlev
