Subject: [U-Boot] [PATCH v2 4/4] arm: imx: mx53loco: remove usage of mx53_dram_size
Date: Mon, 18 Dec 2017 10:02:42 +0100	[thread overview]
Message-ID: <20171218090242.16527-5-linux-kernel-dev@beckhoff.com> (raw)
In-Reply-To: <20171218090242.16527-1-linux-kernel-dev@beckhoff.com>

From: Patrick Bruenn <p.bruenn@beckhoff.com>

Static variables are not available during board_init_f().
'static uint32_t mx53_dram_size[2];' was used in board specific
dram_init(), dram_init_banksize() and get_effective_memsize() to avoid
multiple calls to get_ram_size().

Reused dram initialization functions from arch/arm/mach-imx/mx5/mx53_dram.c

Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com>

---

Changes in v2: None


Only compile tested with make mx53loco_defconfig
