From d8c3ea99826f652efa5e8843f7fb98dfd6f8d194 Mon Sep 17 00:00:00 2001 From: Tien Fong Chee Date: Wed, 23 Jan 2019 14:20:04 +0800 Subject: spl: fat/fs: Add option to include/exclude FAT write build in SPL Most of the time SPL only needs very simple FAT reading, so having CONFIG_IS_ENABLED(FAT_WRITE) to exclude it from SPL build would help to save 64KiB default max clustersize from memory.
