All of the instances of imx_boot_save_loc() do exactly the same thing with the only difference being SoC-specific imx_get_boot_source call.

2018-04-17	7802c6f Browse files » ARM: i.MX6: boot: Return BOOTSOURCE_SPI_NOR, not BOOTSOURCE_SPI ... We use BOOTSOURCE_SPI to denote, among other things, QSPI on i.MX7 and VFxxx, whereas on i.MX6 it is used to mean SPI-NOR. To make functions like imx_xload() work consistently across various i.MX platforms use already existent BOOTSOURCE_SPI_NOR constant to mean booting from SPI-NOR on i.MX6 as well. Replace all in-tree code that relying on the old value as well.
