* [ARM] pxa: make pxa timer initialisation select clock rate at runtimeRussell King2007-10-121-3/+13
| | | | | | | | Rather than using the compile-time constant CLOCK_TICK_RATE, select the clock tick rate at run time. We organise the selection so that PXA3 automatically falls out with the right tick rate. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4550/1: sched_clock on PXA should cope with run time clock rate selectionNicolas Pitre2007-10-122-62/+39
| | | | | | | | | | | | The previous implementation was relying on compile time optimizations based on a constant clock rate. However, support for different PXA flavors in the same kernel binary requires that the clock be selected at run time, so here it is. Let's move this code to a more appropriate location while at it.

| * [POWERPC] Add legacy serial support for OPB with flattened device treeValentine Barshak2007-10-121-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.

| * [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-1223-258/+513
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here. Parts of this patch were originally written by Ben Herrenschmidt. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All ppc32 systems except PReP and 8xx are capable of handling 3G of user address space. Old legacy had set this to 2GB and no one has bothered to fix it. 8xx could be bumped up to 3GB if its SW TLB miss handlers were fixed up to properly determine kernel/user addresses.

Now that more decoupling has occurred we can remove <asm/mpc85xx.h> and some of its legacy. As part of this we moved the definition of CPM_MAP_ADDR into cpm2.h for 85xx platforms.
