[U-Boot] mkconfig arch link generation
Hi, I'm updating my uboot to mainline and I have a question about a link generate from mkconfig (with mpc5121_config). Follwing link in include/asm, I found a link named arch genarated by mkconfig. This is broken so point to arch-mpc512x instead of arch/powerpc/cpu/mpc512x. Result is #include asm/arch/asm-offsets.h or similar are be broken. How is the correct way to modify mkconfig? I don't understand mean of link points arch-mpc512x. Regards, Matteo Facchinetti ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

However, all boards in the mainline using the MPC512x are compiled clean. This is because asm-offsets.h is included only by arch/powerpc/cpu/mpc512x/start.S with #include asm-offsets.h, and the compiler search for the file in the same directory of start.S and can find it. The link is not required to compile the 512x boards supported currently by u-boot, but it must be set for the ARM architecture. Under the kernel, asm-offsets.h is auto-generated (I know, this is the best solution). However, why do you need this file ? It should be required only by low level initialization in assembly, as it is done by start.S. After that, it is required in u-boot to access to registers/peripherals via C structures and not using offsets. Result is #include asm/arch/asm-offsets.h or similar are be broken. How is the correct way to modify mkconfig? Probably not setting the link for powerpc, because it is not required.

Yes, you're rigth, but I'm tring to write nand_spl driver for add nand boot support for my TWR-MPC5125 evaluation board. In first step I take what I need from LTIB (freescale) and then I adjust the code for uboot mainline. The part takes from LTIB of 2k first stage nandboot code uses directly SRAMBAR and SWCRR defines. Now, I suppose, correct develop is to use the common c code in nand_spl directory and eventually customizing for my board unless use include/asm/arch/... for powerpc arch. Is it true? Result is #include asm/arch/asm-offsets.h or similar are be broken. How is the correct way to modify mkconfig? Probably not setting the link for powerpc, because it is not required.
