Subject: [U-Boot] [PATCH] arm: New stack pointer is already aligned
Date: Wed, 27 Nov 2013 14:35:30 -0500	[thread overview]
Message-ID: <1385580930-9830-1-git-send-email-trini@ti.com> (raw)

The code in arch/arm/lib/board.c::board_init_f that sets
gd->start_addr_sp has already make sure we're 8-byte aligned, so we
don't need to do that again.
