[PATCH 3/5] hw/arm: Remove the 'musicpal' machine
Peter Maydell <[email protected]>
| Newsgroups | org.nongnu.qemu-arm,org.nongnu.qemu-devel |
|---|---|
| Message-ID | <[email protected]> |
The 'musicpal' machine emulates the Freecom MusicPal, which was an
"internet radio" released in the mid-2000s. The stock system used a
2.6.16 Linux kernel, but as far as I'm aware, support for the
hardware was never upstreamed to the mainline kernel.
There are a number of reasons for deprecating this board:
* The hardware is now solidly obsolete
* It was never supported in mainline Linux
* The SoC is a Marvell one with no public datasheet
* The only QEMU changes to it have been the usual tree wide
updates and refactoring work
* The only bug report we've ever had about it has been one of
the usual "bug found by static analysis" kind
But in fact we can just drop it immediately, because in commit
59754f85ed35 ("target/arm: Do memory type alignment check when
translation disabled") in 2024 we broke the boot of the standard
firmware image for this board. (The image's u-boot does a LDRH to an
unaligned address, which is UNPREDICTABLE; we used to let it through,
but that commit makes it take a Data Abort, so the image crashes
before it boots the kernel.) Since nobody complained, we can deduce
that nobody's actually using this machine.
Remove the machine proper, and note this in the docs. Devices used
only by this board will be removed in subsequent commits.
