From 96b97fa3110f9a7d8bdb097995511fd78f966043 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 12 Jul 2021 12:42:14 -0400 Subject: m68k: Remove M52277EVB board This board has not been converted to CONFIG_DM_MMC by the deadline. Remove it. As this is also the last in family remove the related support as well.

MEMORY MAP UNDER U-BOOT AND LINUX KERNEL -=========================================== -2.1. System memory map: - Flash: 0x00000000-0x3FFFFFFF (1024MB) - DDR: 0x40000000-0x7FFFFFFF (1024MB) - SRAM: 0x80000000-0x8FFFFFFF (256MB) - IP: 0xF0000000-0xFFFFFFFF (256MB) - -2.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and - linux kernel, you can customize it based on your system requirements: - Flash0: 0x00000000-0x00FFFFFF (16MB) - - DDR: 0x40000000-0x4FFFFFFF (64MB) - SRAM: 0x80000000-0x80007FFF (32KB) - IP: 0xFC000000-0xFC0FFFFF (64KB) - -3.
