From mboxrd@z Thu Jan 1 00:00:00 1970 From: Fabio Estevam Date: Mon, 17 Sep 2018 14:09:02 -0300 Subject: [U-Boot] [RFC] colibri_imx7: Do not hardcode the memory size Message-ID: <1537204142-10226-1-git-send-email-festevam@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Instead of hardcoding the memory size, use the generic imx_ddr_size() function, which extracts the memory size in runtime by reading the DDR controller registers. This helps in supporting 512MB and 1GB modules. Signed-off-by: Fabio Estevam --- Hi Stefan, I don't have the hardware to test, but I think we should be good by using imx_ddr_size() here. board/toradex/colibri_imx7/colibri_imx7.c | 2 +- include/configs/colibri_imx7.h | 1 - 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/board/toradex/colibri_imx7/colibri_imx7.c b/board/toradex/colibri_imx7/colibri_imx7.c index 2b7591e..9029c0b 100644 --- a/board/toradex/colibri_imx7/colibri_imx7.c +++ b/board/toradex/colibri_imx7/colibri_imx7.c @@ -52,7 +52,7 @@ DECLARE_GLOBAL_DATA_PTR; int dram_init(void) { - gd->ram_size = get_ram_size((void *)PHYS_SDRAM, PHYS_SDRAM_SIZE); + gd->ram_size = imx_ddr_size(); return 0; } diff --git a/include/configs/colibri_imx7.h b/include/configs/colibri_imx7.h index ff6bd67..02849ba 100644 --- a/include/configs/colibri_imx7.h +++ b/include/configs/colibri_imx7.h @@ -14,7 +14,6 @@ #include "mx7_common.h" /*#define CONFIG_DBG_MONITOR*/ -#define PHYS_SDRAM_SIZE SZ_1G /* Size of malloc() pool */ #define CONFIG_SYS_MALLOC_LEN (32 * SZ_1M) -- 2.7.4
