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

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