I have read the Documentation/powerpc/booting-without-of.txt and I am still not clear on how manifest constants in platform_get_resource() get translated to items in dts file. Example: in drivers/ide/legacy/ide_platform.c there is code that looks like this. res_base = platform_get_resource(pdev, IORESOURCE_IO, 0); res_alt = platform_get_resource(pdev, IORESOURCE_IO, 1); if (!res_base || !res_alt) { res_base = platform_get_resource(pdev, IORESOURCE_MEM, 0); res_alt = platform_get_resource(pdev, IORESOURCE_MEM, 1); If I want to specify IORESOURCE_MEM (0) and IORESOURCE_MEM ( 1) addresses in my board specific what statements do I need to include in my dts file? I have tried including them in memory {} section of dts and that doesn't work. Would appreciate help/pointer. /Subodh Nijsure (Standard Disclaimers Apply)
