[U-Boot] [PATCH 07/11] board: ti: am335x: Add platdata for cpsw in SPL

Subject: [U-Boot] [PATCH 07/11] board: ti: am335x: Add platdata for cpsw in SPL
Date: Mon, 18 Mar 2019 13:54:37 +0530	[thread overview]
Message-ID: <20190318082441.16635-8-faiz_abbas@ti.com> (raw)
In-Reply-To: <20190318082441.16635-1-faiz_abbas@ti.com>

The SPL image overflows when cpsw dt nodes are added and SPL_OF_CONTROL
is enabled. Use static platdata instead to save space.
