From 56c91bc3b6be0551113df0eb1f0c8b1a597b9da1 Mon Sep 17 00:00:00 2001 From: Simon Schwarz Date: Mon, 31 Oct 2011 06:34:45 +0000 Subject: Fix regression in SMDK6400 s3c64xx.c implemented its own nand_read_byte, nand_write_buf and nand_read_buf functions. This provoked a regression when these functions were made public by patch 55f429bb39614a16b1bacc9a8bea9ac01a60bfc8. This deletes these duplicated functions from s3c64xx.c and adds the generic implementations in nand_base.c to the spl Makefile. It also adds -ffcuntion-sections and -gc-sections to the compilation flags of the SPL to avoid errors originating from unused functions in nand_base.c.
