193 * The ARM boot monitor initializes the board.
194 * However, the default U-Boot code also performs the initialization.
195 * If desired, this can be prevented by defining SKIP_LOWLEVEL_INIT
196 * - see documentation supplied with board for details of how to choose the
197 * image to run at reset/power up
198 * e.g. whether the ARM Boot Monitor runs before U-Boot
200 #define CONFIG_SKIP_LOWLEVEL_INIT
205 * The ARM boot monitor does not relocate U-Boot.
206 * However, the default U-Boot code performs the relocation check,
207 * and may relocate the code if the memory map is changed.
208 * If necessary this can be prevented by defining SKIP_RELOCATE_UBOOT

214 * There are various dependencies on the core module (CM) fitted
215 * Users should refer to their CM user guide
216 * - when porting adjust u-boot/Makefile accordingly
217 * to define the necessary CONFIG_ s for the CM involved
218 * see e.g. cp_926ejs_config
221 #include "armcoremodule.h"
224 * If CONFIG_SKIP_LOWLEVEL_INIT is not defined &
225 * the core module has a CM_INIT register
226 * then the U-Boot initialisation code will
227 * e.g. ARM Boot Monitor or pre-loader is repeated once
228 * (to re-initialise any existing CM_INIT settings to safe values).
230 * This is usually not the desired behaviour since the platform
231 * will either reboot into the ARM monitor (or pre-loader)
232 * or continuously cycle thru it without U-Boot running,
233 * depending upon the setting of Integrator/CP switch S2-4.
235 * However it may be needed if Integrator/CP switch S2-1
236 * is set OFF to boot direct into U-Boot.
237 * In that case comment out the line below.
