This adds support for two additional boot modes on the i.MX7D SoC, which
is most useful when doing U-Boot development on this chip.
1. "bmode usb" can be used to force the ROM boot loader's serial
2. "bmode normal" can be used to revert to the normal boot mode
as specified by fuses and BOOT_MODE pins

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_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>
I missed to add 'add_board_boot_modes(board_boot_modes);'
Now I get:
=> bmode usb

So the board is resetting instead of going into serial download mode.
Any ideas?
I'm not sure. Since I'm currently working with a board with no
fuses blown, I'm getting USB mode either way ;)...
I have an MX7 SABRE SD and I'll try it out there.
Regards,
Eric
