I am using i.MX7ULP now and I want to enable A7 LDO.

I got some clues in of IMX7ULPRMV2_RevC.pdf.

However, I don't know how to modify the parameter (please refer to the following image) of eFuse.

As I know, once the parameter be enabled, M4 will set PMC_0_CTRL[LDOEN] bit and the current of A7 domain will be from the internal LDO. Isn't it?

In addition, I can't find "fuse map" in the document as well.

Could you help me, please?
