From aeb1be536be34fe7992aca7840f34a9313f7b1fe Mon Sep 17 00:00:00 2001 From: Fabio Berton Date: Tue, 18 Oct 2016 11:59:36 -0200 Subject: [PATCH] mx6cuboxi: Use PARTUUID to specify the rootfs location Currently the rootfs location is passed via mmcblk number and the problem with this approach is that the mmcblk number for the eMMC changes depending on the kernel version. In order to avoid such issue, use UUID method to specify the rootfs location. This change was made based on U-Boot commit: - ca4f338e2efece5196eb2178e5f7d07be828da6e Signed-off-by: Fabio Berton Signed-off-by: Otavio Salvador --- include/configs/mx6cuboxi.h | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/include/configs/mx6cuboxi.h b/include/configs/mx6cuboxi.h index 237ef04481..69172486cc 100644 --- a/include/configs/mx6cuboxi.h +++ b/include/configs/mx6cuboxi.h @@ -78,6 +78,9 @@ #define CONFIG_SYS_FSL_USDHC_NUM 1 #define CONFIG_SYS_MMC_ENV_DEV 0 /* SDHC2 */ +#define CONFIG_PARTITION_UUIDS +#define CONFIG_CMD_PART + #define CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG #ifndef CONFIG_SPL_BUILD #define CONFIG_EXTRA_ENV_SETTINGS \ @@ -95,6 +98,7 @@ "console=" CONFIG_CONSOLE_DEV "\0" \ "bootm_size=0x10000000\0" \ "mmcdev=" __stringify(CONFIG_SYS_MMC_ENV_DEV) "\0" \ + "finduuid=part uuid mmc 0:2 uuid\0" \ "update_sd_firmware=" \ "if test ${ip_dyn} = yes; then " \ "setenv get_cmd dhcp; " \ @@ -123,6 +127,7 @@ #define CONFIG_BOOTCOMMAND \ "run findfdt; " \ + "run finduuid; " \ "run distro_bootcmd" #define BOOT_TARGET_DEVICES(func) \ -- 2.40.1
