Hello TI Expert,
HW : SK-AM62
SW : Processor SDK 8.5
Boot mode : eMMC
I've verified SBL EMMC Linux booting with below guide.
However, as shown in the log below, it takes a lot of time in SBL stage1/2(about 2.5sec). This can affect overall Linux boot time.

Is there any way to reduce the SBL boot time?
