Subject: [U-Boot] [PATCH V6 07/11] ARM: OMAP3: Get rid of omap3_gp_romcode_call and replace with omap_smc1
Date: Mon, 9 Mar 2015 17:12:05 -0500	[thread overview]
Message-ID: <1425939129-308-8-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1425939129-308-1-git-send-email-nm@ti.com>

omap_smc1 is now generic enough to remove duplicate
omap3_gp_romcode_call logic that omap3 introduced.

As part of this change, move to using the generic lowlevel_init.S for
omap3 as well.
