When booting a mainline kernel on warp7 we have:
- mmc0: Wifi SDIO chip
- mmc1: eMMC
, so point CONFIG_MMCROOT to use mmcblk1 instead.

As far as I know, the sold WaRP7 boards are shipped with the NXP kernel so if this patch is applied, the U-Boot won't work out of box for most of users
Currently U-Boot mainline does not boot NXP kernel, so I am not breaking anything here.
Well ...
warp7: Select secure boot
In order to boot NXP 4.1.15 we need to boot in secure mode.
So enable the variable CONFIG_ARMV7_BOOT_SEC_DEFAULT by default.

From Breno, sent to the mailing list, does fix this and so it does work.
To better handle NXP kernel I can add a 'warp7_secure_defconfig' and then do like this to handle the mmcroot:
--- a/include/configs/warp7.h +++ b/include/configs/warp7.h @@ -113,7 +113,11 @@
#define CONFIG_SYS_MMC_ENV_DEV 0 #define CONFIG_SYS_MMC_ENV_PART 0 -#define CONFIG_MMCROOT "/dev/mmcblk2p2" +#ifdef CONFIG_ARMV7_BOOT_SEC_DEFAULT +#define CONFIG_MMCROOT "/dev/mmcblk2p2" /* NXP kernel */ +#else +#define CONFIG_MMCROOT "/dev/mmcblk1p2" /* Mainline kernel */ +#endif
Someone using mainline kernel is expected to know how to set mmcroot variable or so. I would not include this patch at all.
