Change 128680 by gonzo at gonzo_jeeves on 2007/11/05 13:29:17

	o Make new interface for platform_start. Now this function
	    accepts for arguments of __register_t which correspond
	    to a0..a3 registers respectively. It's up to platform_start
	    implementation to use them in a machine-dependent fashion.
	o MALTA board obtaines memory size from a3 register
