194 * The ARM boot monitor initializes the board.

198 * image to run at reset/power up
199 * e.g. whether the ARM Boot Monitor runs before U-Boot
201 #define CONFIG_SKIP_LOWLEVEL_INIT
206 * The ARM boot monitor does not relocate U-Boot.
207 * However, the default U-Boot code performs the relocation check,
208 * and may relocate the code if the memory map is changed.
209 * If necessary this can be prevented by defining SKIP_RELOCATE_UBOOT

215 * There are various dependencies on the core module (CM) fitted
216 * Users should refer to their CM user guide

218 * to define the necessary CONFIG_ s for the CM involved
219 * see e.g. cp_926ejs_config
222 #include "armcoremodule.h"
225 * If CONFIG_SKIP_LOWLEVEL_INIT is not defined &
226 * the core module has a CM_INIT register
227 * then the U-Boot initialisation code will
228 * e.g. ARM Boot Monitor or pre-loader is repeated once
229 * (to re-initialise any existing CM_INIT settings to safe values).
231 * This is usually not the desired behaviour since the platform
232 * will either reboot into the ARM monitor (or pre-loader)
233 * or continuously cycle thru it without U-Boot running,
234 * depending upon the setting of Integrator/CP switch S2-4.
236 * However it may be needed if Integrator/CP switch S2-1
237 * is set OFF to boot direct into U-Boot.
238 * In that case comment out the line below.
