doc: usage: Add general rule for `$?`

2025-10-26T15:03:35Z

For nearly all commands in U-Boot the '?' variable is handled the same way with 0 meaning success, 1 meaning any failure. Explain this in the general rules section of the cmdline documentation (with a link to a counter example) and then remove the redundant wording from most commands. We retain a section about the return value in a number of places where we are doing something such as always returning a specific value or we have useful additional information to go along with the normal return codes.

cmd: Add pause command

2022-09-02T17:40:42Z

This command is being introduced with the goal of allowing user-friendly "generic use case" U-Boot builds to pause until user input under some situations. The main use case would be when a boot failure happens, to pause until the user has had time to acknowledge the current state. Tested using: make && ./u-boot -v -T -c 'ut lib lib_test_hush_pause' Signed-off-by: Samuel Dionne-Riel Cc: Simon Glass
