CONFIG_DW_AXI_BURST_LEN is always defined in designware.h in the same patch. +/* Default AXI BUS Burst length */ +#ifndef CONFIG_DW_AXI_BURST_LEN +#define CONFIG_DW_AXI_BURST_LEN 0 +#endif + Regards, Sonic _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
