commit 9b6a51aab5f5f9f71d2fa16e8b4d530e1643dfcb upstream.
With subtle timings changes, we can now sometimes get an external abort on non-linefetch error booting am3 devices at sysc_reset(). This is because of a missing reset delay needed for the usb target module.
Looks like we never enabled the delay earlier for am3, although a similar issue was seen earlier with a similar usb setup for dm814x as described in commit ebf244148092 ("ARM: OMAP2+: Use srst_udelay for USB on dm814x").
