SDHC1 emmc boot for imx8mini

[Partrick_Bin]

Hello everyone,

When designing imX8Mini hardware, customers will switch emmc from SDHC3 to SDHC1.
I have some questions about the following part of the imx8M Mini Reference Manual. The RM contains the following information:

ECSPI2 and ECSPI1 in the reference manual are not configured with alt2 MUX.SD3_DATA could not be queried in the manual.

I have some questions about the description of this chapter.

I have some questions about whether emmc can be boot with SDHC1 in imx8Mini.
Whether emmc can be boot in SDHC1. 

How should I configure emmc if it can be boot from SDHC1?

Thank you for your attention

The emmc can be boot in SDHC1. You need to configure the SDHC1 clock in u-boot. The details on the SDHC1 configuration I will share to you later.
