i.MX 7 has a Boot Information structure which is passed from the Boot ROM, so we have a much cleaner method there. http://git.denx.de/?p=u-boot/u-boot-imx.git;a=blob;f=arch/arm/mach-imx/mx7/soc.c;h=87bf105f385d4c12bee6d038c0ba50e2e588124c;hb=HEAD#l392 As far as I can tell this boot information structure is also accurate when the Boot ROM entered serial downloader as a fallback. Do we have boards using SPL on i.MX 7? -- Stefan _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
