From mboxrd@z Thu Jan 1 00:00:00 1970 From: linux-kernel-dev at beckhoff.com Date: Mon, 18 Dec 2017 10:02:39 +0100 Subject: [U-Boot] [PATCH v2 1/4] arm: imx: cx9020: remove usage of mx53_dram_size In-Reply-To: <20171218090242.16527-1-linux-kernel-dev@beckhoff.com> References: <20171218090242.16527-1-linux-kernel-dev@beckhoff.com> Message-ID: <20171218090242.16527-2-linux-kernel-dev@beckhoff.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Patrick Bruenn 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(). However multiple calls are better than undefined behavior...
