The SPARC and PPC targets currently have a fragment of target-specific information about the -g and -prom options which would be better placed as part of the general documentation of those options in qemu-options.hx. Move the relevant information to those locations. SPARC also has a bit of text about the -M option which is out of date and provides no useful information over the generic documentation of that option, so just delete it. The motivation here is again to avoid having to awkwardly include this text into the rST version of the qemu.1 manpage.

The emulation is somewhat complete. SMP up to 16 CPUs is supported,
|
|
but Linux limits the number of usable CPUs to 4.

@end itemize

The number of peripherals is fixed in the architecture. Maximum
|
|
memory size depends on the machine type, for SS-5 it is 256MB and for
|
|
others 2047MB.

Since version 0.8.2, QEMU uses OpenBIOS
|
|
@url{https://www.openbios.org/}. OpenBIOS is a free (GPL v2) portable
|
|
firmware implementation. The goal is to implement a 100% IEEE
|
|
1275-1994 (referred to as Open Firmware) compliant firmware.
|
|
|
|
A sample Linux 2.6 series kernel and ram disk image are available on
|
|
the QEMU web site. There are still issues with NetBSD and OpenBSD, but
|
|
most kernel versions work. Please note that currently older Solaris kernels
|
|
don't work probably due to interface issues between OpenBIOS and
|
|
Solaris.
