rocm is a noarch package, so it's included on all arches. But it has a lot of dependencies which are archful and built only on x86_64. So on other arches rocm, rocm-devel and rocm-test are all uninstallable due to a big list of missing deps:

package: rocm-7.2.0-3.eln155.noarch from file:///mnt/update_repo
  amdsmi >= 7.2
  hipblas >= 7.2
  hipcc
  hipfft >= 7.2
  hiprand >= 7.2
  hipsolver >= 7.2
  hipsparse >= 7.2
  rocblas >= 7.2
  rocfft >= 7.2
  rocm-clang
  rocm-hip >= 7.2
  rocm-runtime >= 7.2
  rocm-smi >= 7.2
  rocminfo >= 7.2
  rocrand >= 7.2
  rocsolver >= 7.2
  rocsparse >= 7.2
package: rocm-devel-7.2.0-3.eln155.noarch from file:///mnt/update_repo
  amdsmi-devel >= 7.2

package: rocm-test-7.2.0-3.eln155.noarch from file:///mnt/update_repo
  kfdtest >= 7.2

rocm should be prevented from showing up in other arches, somehow. Either just make it x86_64, or I think there's a way to somehow make it noarch but only show up on x86_64 (something like making the source package archful but all the binary packages noarch or something like that).
