From: Inha Song <[email protected]> This commit extends SMDK5420 board's file by adding functions: - get_dfu_alt_system() - get_dfu_alt_boot()
This allows setting the DFU environment by function set_dfu_alt_info() from: board/samsung/common/misc.c Signed-off-by: Inha Song <[email protected]> Cc: Akshay Saraswat <[email protected]> Cc: Minkyu Kang <[email protected]> --- board/samsung/smdk5420/smdk5420.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) diff --git a/board/samsung/smdk5420/smdk5420.c b/board/samsung/smdk5420/smdk5420.c index 8021f77..88f4044 100644 --- a/board/samsung/smdk5420/smdk5420.c +++ b/board/samsung/smdk5420/smdk5420.c @@ -19,6 +19,7 @@ #include <power/tps65090_pmic.h> #include <i2c.h> #include <lcd.h> +#include <mmc.h> #include <parade.h> #include <spi.h> #include <usb.h> @@ -111,3 +112,32 @@ int board_usb_init(int index, enum usb_init_type init) return dwc3_uboot_init(&dwc3_device_data); } #endif +#ifdef CONFIG_SET_DFU_ALT_INFO +char *get_dfu_alt_system(char *interface, char *devstr) +{ + return getenv("dfu_alt_system"); +} + +char *get_dfu_alt_boot(char *interface, char *devstr) +{ + struct mmc *mmc; + char *alt_boot; + int dev_num; + + dev_num = simple_strtoul(devstr, NULL, 10); + + mmc = find_mmc_device(dev_num); + if (!mmc) + return NULL; + + if (mmc_init(mmc)) + return NULL; + + if (IS_SD(mmc)) + alt_boot = CONFIG_DFU_ALT_BOOT_SD; + else + alt_boot = CONFIG_DFU_ALT_BOOT_EMMC; + + return alt_boot; +} +#endif -- 1.9.1 _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
