            Bug ID: 85661
           Summary: Double Firmware for Radeon GPUs (at least HAWAII)
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.17.0
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: debian at carbon-project.org
                CC: alexdeucher at gmail.com
        Regression: No

Not sure if this is a mistake or I'm missing something here, but I was looking
at
<https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/radeon>
and noticed, that there are firmware files of the same name – except case – but
different content for HAWAII and others, eg. HAWAII_ce.bin and hawaii_ce.bin:
7fa992d86295f741e8cdea76c5b6c632  linux-firmware/radeon/HAWAII_ce.bin
9e05820da42549ce9c89d147cf1f8e19  linux-firmware/radeon/hawaii_ce.bin
For other firmware parts (eg. mc2) there is only one version available.

Now the question is: is this intended? Or should there only be one version? If
I had to guess, I'd say the lower-case variants are the current ones, since
they have the same checksums as the firmware I've downloaded from
<http://people.freedesktop.org/~agd5f/radeon_ucode/> in the course of
<https://bugs.freedesktop.org/show_bug.cgi?id=78453>.
