sh: kexec: Add PHYSICAL_START

2011-10-28T06:03:43+00:00

Add PHYSICAL_START kernel configuration parameter to set the address at
which the kernel should be loaded.

It has been observed on an sh7757lcr that simply modifying MEMORY_START
does not achieve this goal for 32bit sh. This is due to MEMORY_OFFSET in
arch/sh/kernel/vmlinux.lds.S bot being based on MEMORY_START on such
systems.

Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHG

2011-08-03T15:12:37+00:00

cmpxchg() is widely used by lockless code, including NMI-safe lockless
code.  But on some architectures, the cmpxchg() implementation is not
NMI-safe, on these architectures the lockless code may need a
spin_trylock_irqsave() based implementation.

This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that
NMI-safe lockless code can depend on it or provide different
implementation according to it.

On many architectures, cmpxchg is only NMI-safe for several specific
operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch
only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

virtio: expose for non-virtualization users too

2011-07-23T06:50:30+00:00

virtio has been so far used only in the context of virtualization,
and the virtio Kconfig was sourced directly by the relevant arch
Kconfigs when VIRTUALIZATION was selected.

Now that we start using virtio for inter-processor communications,
we need to source the virtio Kconfig outside of the virtualization
scope too.

Moreover, some architectures might use virtio for both virtualization
and inter-processor communications, so directly sourcing virtio
might yield unexpected results due to conflicting selections.

The simple solution offered by this patch is to always source virtio's
Kconfig in drivers/Kconfig, and remove it from the appropriate arch
Kconfigs. Additionally, a virtio menu entry has been added so virtio
drivers don't show up in the general drivers menu.

This way anyone can use virtio, though it's arguably less accessible
(and neat!) for virtualization users now.

Note: some architectures (mips and sh) seem to have a VIRTUALIZATION
menu merely for sourcing virtio's Kconfig, so that menu is removed too.

sh: add to select the new configuration for USB EHCI/OHCI

2011-06-24T08:53:10+00:00

Because the USB EHCI/OHCI driver has new configuration for SH,
the patch enables the EHCI and/or OHCI driver of the on-chip for
some CPUs.

sh: Update shmin to reflect PIO dependency.

2011-05-24T08:33:51+00:00

shmin uses __set_io_port_base() for legacy I/O mapping that ethernet and
other SuperI/O functions depend on. Ensure that PIO support is built in
until the board is updated for MMIO properly.
