From 736b491f31ee49689ba80e2ab0897004f4502362 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 26 Nov 2019 09:34:49 +0100 Subject: [PATCH] ARM: mx6: ddr: Make debug prints work with tiny printf The %08X format returns just zeroes with tiny printf, which is horribly confusing, especially when debugging DRAM calibration problems. Change the format to %08x (with lowercase x), which behaves correctly with either implementation of printf in SPL.
