With this patch-set applied most of the low-level code in the kernel
supports both LEON and SUN.
The only references left are in:
arch/sparc/Kconfig
arch/sparc/kernel/Makefile
arch/sparc/kernel/ioport.c
arch/sparc/kernel/process_32.c
drivers/pci/Makefile
drivers/usb/Kconfig
drivers/usb/host/Kconfig
drivers/usb/host/ehci-hcd.c
drivers/usb/host/uhci-hcd.c
I need to analyse things a bit before attacking the last users,
and wanted to get this batch out for review (and eventually applied).
I expect some variant (like SPARC_LEON_PCI) to continue to
be present - but lets see.
Changes since the [RFC] version:
- used more optimal assembler as suggested by davem
- fix up error message as pointed out by davem
- fix up error message as pointed out by Julian Calaby
- use LEON as default and patch for SUN (which uncovered a bug - good!)
- added several patches...
This version boots on my ss5.
If I build a LEON variant the build fails when it starts to
probe my SCSI drive (I think it was here). This was expected
since ioport is not fixed up yet. Before it would fail much earlier.
Also note that all references to SPARC_LEON is gone in the header files,
so only a minimal set of files are rebuild when you go from non-LEON
to a LEON build.
I have done builds on some configurations for each step - but
my current build-box is slow so I did not cover all.
And I have boot tested the kernel for almost all steps.
So my confidence in the patch-set i good.
