U-Boot, hush and pipes
Greetings
I've been digging into the hush parser and finding, what appear to be, odd things.
Obviously masses of the hush functionality has been removed using the __U_BOOT__ #define but some bits that are left seem to be not relevant to the bootloader environment. I'm particularly confused by the pipe operators '&' and '|' and how they are used in u-boot. Is this just a mistake? or am I (as usual) missing something...
A quick pass with gcc -E -D__U_BOOT__ is most revealing :-))
