2007-07-10[POWERPC] Modify sched_clock() to make CONFIG_PRINTK_TIME more saneTony Breeds1-3/+6
When booting a current kernel with CONFIG_PRINTK_TIME enabled you'll see messages like: [ 0.000000] time_init: decrementer frequency = 188.044000 MHz [ 0.000000] time_init: processor frequency = 1504.352000 MHz [3712914.436297] Console: colour dummy device 80x25 This cause by the initialisation of tb_to_ns_scale in time_init(), suddenly the multiplication in sched_clock() now does something :). This patch modifies sched_clock() to report the offset since the machine booted so the same printk's now look like: [ 0.000000] time_init: decrementer frequency = 188.044000 MHz [ 0.000000] time_init: processor frequency = 1504.352000 MHz [ 0.000135] Console: colour dummy device 80x25 Effectivly including the uptime in printk()s. This patch makes tb_to_ns_scale and tb_to_ns_shift static and read_mostly for good measure. Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-07-10[POWERPC] PS3: Bootwrapper support.Geoff Levand7-11/+542
Add support to build the PS3 flash rom image and remove some unneeded lmb calls. The PS3's lv1 loader supports loading gzipped binary images from flash rom to addr zero. The loader enters the image at addr 0x100. In this implementation a bootwrapper overlay is use to arrange for the kernel to be loaded to addr zero and to have a suitable bootwrapper entry at 0x100. To construct the rom image, 0x100 bytes from offset 0x100 in the kernel is copied to the bootwrapper symbol __system_reset_kernel. The 0x100 bytes at the bootwrapper symbol __system_reset_overlay is then copied to offset 0x100. At runtime the bootwrapper program copies the 0x100 bytes at __system_reset_kernel to addr 0x100. zImage.ps3 is a wrapped image that contains a flat device tree, an lv1 compatible entry point, and an optional initrd. otheros.bld is the gzip compresed rom image built from zImage.ps3. otheros.bld is suitable for programming into the PS3 boot flash memory.

2007-07-10[POWERPC] Make the debugfs "powerpc" dir globally accessibleMichael Ellerman3-6/+18
The prom.c debugging code creates a "powerpc" directory in debugfs, which is nice, but doesn't allow any other debugging code to stick things under "powerpc" in debugfs. So make it global. While we're there we should make the prom.c debugging code depend on CONFIG_DEBUG_FS, because it doesn't work otherwise.

2007-07-10[POWERPC] Add a warning to help trackdown device_node refcounting bugsMichael Ellerman2-0/+12
When the refcount for a device node goes to 0, we call the destructor - of_node_release(). This should only happen if we've already detached the node from the device tree. So add a flag OF_DETACHED which tracks detached-ness, and if we find ourselves in of_node_release() without it set, issue a warning and don't free the device_node. To avoid warning continuously reinitialise the kref to a sane value. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-10[POWERPC] Generalise device_node flag interfaceMichael Ellerman3-5/+13

2007-07-10[POWERPC] Check for the root node in of_detach_node()Michael Ellerman1-0/+3

2007-07-10[POWERPC] Add cputable entry for PowerPC 440SPe Rev. BRoland Dreier1-5/+15
When adding the cputable entry for 440SPe Rev. B, we also need to adjust the existing entries for 440SP Rev. A and 440SPe Rev. B so that they look more bits of the PVR. The 440SPe Rev. B has PVR 53421891, which would match the current 440SP Rev. A pattern of 53xxx891. To distinguish between 440SP and 440SPe, we need to use the first three digits of the PVR, which are respectively 532 and 534.
