From 1c1c8a3a990742a73a75b091c35213b0a50f0c45 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 21 Oct 2019 17:26:43 -0600 Subject: [PATCH] tiny-printf: Reduce size by removing ctype The ctype array is brought into the image, adding 256 bytes, when it is unlikely to be needed. The extra code for %p is only present when DEBUG is defined, so let's drop ctype as well unless DEBUG is defined.
