From e5509ce87b29f773b045200735bec2903b72eed4 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 1 Oct 2023 19:13:13 -0600 Subject: cli: Create a function to process characters Move most of the inner loop from cread_line() into a new function. This will allow using it from other code. This involves adding a few more members to the state struct.
