Isn't that switch statement equivalent to -always- breaking, as in:

+	while (pa_data) {
+		data = early_ioremap(pa_data, PAGE_SIZE);
+		break;

I doubt you want to do that.  I suppose what you want to do is check for
data == NULL instead, as in:

+	while (pa_data) {
+		data = early_ioremap(pa_data, PAGE_SIZE);
+		if (!data)
+			break;

???
