[U-Boot] mx53loco_defconfig failure with Buildroot toolchain

[U-Boot] mx53loco_defconfig failure with Buildroot toolchain

[Fabio Estevam]

Hi,

When I try to build mx53loco_defconfig in U-boot 2016.05 I get the
following errors with the toolchain provided by Buildroot:

  LD      u-boot
/home/fabio/buildroot/output/host/usr/bin/arm-buildroot-linux-uclibcgnueabihf-ld.bfd:

Does anyone have any suggestion on how to fix this error?

Thanks

Yes, this is the IPU - rather a patch to fix this was not included for
the release, I applied it later:


commit c510f2e436008e55a50b063f2180cb1e63984224
Author: Peng Fan <van.freenix@gmail.com>

    video: ipu_common: fix build error

    Some toolchains fail to build
    "clk->rate = (u64)(clk->parent->rate * 16) / div;"
    And the cast usage is wrong.

    Use the following code to fix the issue,
    "
      do_div(parent_rate, div);
      clk->rate = parent_rate;
    "

That's correct. I applied this patch and that fixes the issue, thanks!
