From 5044c9cc6c4dffb2959769a785663f46cb418461 Mon Sep 17 00:00:00 2001 From: "angelo@sysam.it" Date: Wed, 27 Apr 2016 21:50:44 +0200 Subject: m68k: add malloc memory for early malloc To use serial uclass and DM, CONFIG_SYS_MALLOC_F must be used. So CONFIG_SYS_GENERIC_GLOBAL_DATA has been undefined and call to board_init_f_mem() is added for all cpu's.
