On the iMX6 Sabre Lite, there is a bin file called iMX6DQ_SPI_touSDHC4.bin which allows boot from SD instead of NOR flash (default).. It's also known as a "shim". At first inspection of the binary file, it doesn't seem to follow the rules for a Plugin Image as described in Section 8.7 of the latest reference manual Rev 0.
Is this shim the same as a Plugin Image?
Does anyone have the source for this binary image?
I am wondering if there is any source code examples for implementing a Plugin Image to change the boot source for iMX6.
