[ Upstream commit 7a3b8758bd6e45f7b671723b5c9fa2b69d0787ae ]
Compile-testing the ixp4xx timer with CONFIG_OF enabled but
CONFIG_TIMER_OF disabled leads to a harmless warning:
arm-linux-gnueabi-ld: warning: orphan section `__timer_of_table' from `drivers/clocksource/timer-ixp4xx.o' being placed in section `__timer_of_table'
Move the select statement from the platform code into the driver
so it always gets enabled in configurations that rely on it.

config IXP4XX_INDIRECT_PCI

bool "Use indirect PCI memory access"
|
|
depends on PCI
|
|
help
|
|
IXP4xx provides two methods of accessing PCI memory space:
|
|
|
|
1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
|
|
To access PCI via this space, we simply ioremap() the BAR
|
|
into the kernel and we can use the standard read[bwl]/write[bwl]
|
|
macros. This is the preferred method due to speed but it
|
|
limits the system to just 64MB of PCI memory. This can be
|
|
problematic if using video cards and other memory-heavy devices.
|
|
|
|
2) If > 64MB of memory space is required, the IXP4xx can be
|
|
configured to use indirect registers to access the whole PCI
|
|
memory space. This currently allows for up to 1 GB (0x10000000
|
|
to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
|
|
is that every PCI access requires three local register accesses
|
|
plus a spinlock, but in some cases the performance hit is
|
|
acceptable. In addition, you cannot mmap() PCI devices in this
|
|
case due to the indirect nature of the PCI window.
|
|
|
|
By default, the direct method is used. Choose this option if you
|
|
need to use the indirect method instead. If you don't know
|
|
what you need, leave this option unselected.
