I tried testing your patch on a imx7d sabresd, but it seems there is
an issue with bmode that is unrelated to your patch.

I also did:

diff --git a/configs/mx7dsabresd_defconfig b/configs/mx7dsabresd_defconfig
index 8f2e33a..c70fde8 100644
--- a/configs/mx7dsabresd_defconfig
+++ b/configs/mx7dsabresd_defconfig
@@ -5,7 +5,6 @@ CONFIG_VIDEO=y
 # CONFIG_ARMV7_VIRT is not set
 CONFIG_IMX_RDC=y
 CONFIG_IMX_BOOTAUX=y
-# CONFIG_CMD_BMODE is not set
 CONFIG_DEFAULT_DEVICE_TREE="imx7d-sdb"
 CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx7dsabresd/imximage.cfg"
 CONFIG_BOOTDELAY=3

so that bmode command can be added.

However I am getting:

=> bmode usb
bmode - <NULL>

Usage:
bmode
=> bmode normal
bmode - <NULL>

Usage:
bmode
=>

Any ideas?

Thanks
