From da37d096820e15b2bcdb0243da2dc01707c650f2 Mon Sep 17 00:00:00 2001 From: Jörg Krause Date: Sun, 14 Jan 2018 19:26:37 +0100 Subject: mtd: nand: export nand_get_flash_type function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `nand_get_flash_type()` allows identification of supported NAND flashs. The function is useful in SPL (like mxs_nand_spl.c) to lookup for a NAND flash (which does not support ONFi) instead of using nand_simple.c and hard-coding all required NAND parameters.
