I am looking for boot mode and fuse register settings in IMX7 reference manual. I can see the option for selecting SD and eMMC port in internal boot mode.


BOOT_CFG[11:10] -  USDHC Port Selection

00                            -   USDHC-1

01                            -   USDHC-2
10                            -   USDHC-3
else                         - reserved


But I cannot find the fuse register settings for selecting SDHC ports in fuse mode. I can only see the values for 0x470[7:0] register. (Table 6-11. SD/eSD Boot Fusemap in TRM). 


Can anyone say, how eMMC port selection can be programmed in fuse mode?  I mean, in IMX6, I can find these details in 0x450[15:8] register in Table 5-8. MMC/eMMC Boot Fusemap.
