[U-Boot] Relocation

Hi, Albert:

I have ever tried to del these code in crt0.S :
	ldr	sp, [r8, #GD_START_ADDR_SP]	/* r8 =
gd->start_addr_sp */
	bic	sp, sp, #7	/* 8-byte alignment for ABI compliance
*/
	ldr	r8, [r8, #GD_BD]		/* r8 = gd->bd */
	sub	r8, r8, #GD_SIZE		/* new GD is below bd */

	/// tricky code : insure to return here after running
relocate_code.
	adr	lr, here
	ldr	r0, [r8, #GD_RELOC_OFF]		/* lr =
gd->start_addr_sp */
	add	lr, lr, r0
	ldr	r0, [r8, #GD_RELOCADDR]		/* r0 = gd->relocaddr */
	/// start.S implement this function.
	b	relocate_code

Then no relocation, it seemed OK.

Best wishes,
