Hi Pali,
I got burned for being lazy :) it turned out that the mix of #ifdef and #if defined was the problem. Just stepped away and came back for a few minutes and I can see that I just need to define the CONFIG_DDR4 properly in arch/arm/mach-mvebu/Kconfig and build it to pass the CONFIG_DDR4 stuff.
One more small hurdle after that was CONFIG_USE_PRIVATE_LIBGCC must be undefined for it to build (so I am using /usr/lib/gcc/arm-linux-gnueabi/10/libgcc.a, and not using arch/arm/lib/lib.a)
Hello! It is normally a good idea to unset CONFIG_USE_PRIVATE_LIBGCC unless you have compiled gcc for target CPU.
CONFIG_USE_PRIVATE_LIBGCC was set as a default for ARM target, since u-boot has arch/arm/lib/lib.a. But using arch/arm/lib/lib.a I got several build errors like these:
ld.bfd: drivers/ddr/marvell/a38x/mv_ddr4_training_calibration.o: in function `mv_ddr4_copt_get': /usr/src/u-boot/drivers/ddr/marvell/a38x/mv_ddr4_training_calibration.c:809: undefined reference to `__aeabi_i2d' ld.bfd: /usr/src/u-boot/drivers/ddr/marvell/a38x/mv_ddr4_training_calibration.c:809: undefined reference to `__aeabi_dmul' ld.bfd: /usr/src/u-boot/drivers/ddr/marvell/a38x/mv_ddr4_training_calibration.c:809: undefined reference to `__aeabi_d2uiz'
This looks like a bug in that training code. I would need to see source code, so I can figure out how to fix it.
Have you solved this issue? Or if not, can you show what you had on that problematic line 809?
