Subject: ARM: mx6: ddr: Make debug prints work with tiny printf
X-Git-Tag: v2020.04-rc1~37^2~50
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=736b491f31ee49689ba80e2ab0897004f4502362;p=oweals%2Fu-boot.git

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.
