From fc2d0302b666cd127fca3a8a800f33841de11c41 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 20 Apr 2018 18:14:25 +0900 Subject: [PATCH] mmc: uniphier-sd: skip clock set-up for SPL The size of SPL is hitting the limit (64KB) for uniphier_v7_defconfig. When booting from SD/eMMC, obviously its clock has been properly set up by the boot ROM. Acutually, no need to re-initialize the clock in SPL. Using a clock driver would generalize the SoC specific code, but solving the memory footprint problem would win.
