* powerpc: Copy bootable images in the default install scriptGrant Likely2009-01-08
| | | | | | | | | | | | | | | | | | | This patch makes the default install script (arch/powerpc/boot/install.sh) copy the bootable image files into the install directory. Before this patch only the vmlinux image file was copied. This patch makes the default 'make install' command useful for embedded development when $(INSTALL_PATH) is set in the environment. As a side effect, this patch changes the calling convention of the install.sh script. Instead of a single 5th parameter, the script is now passed a list of all the target images stored in the $(image-y) Makefile variable. This should be backwards compatible with existing install scripts since it just adds additional arguments and does not change existing ones.

| | * USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]Vitaly Bordug2009-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A published errata for ppc440epx states, that when running Linux with both EHCI and OHCI modules loaded, the EHCI module experiences a fatal error when a high-speed device is connected to the USB2.0, and functions normally if OHCI module is not loaded. There used to be recommendation to use only hi-speed or full-speed devices with specific conditions, when respective module was unloaded. Later, it was observed that ohci suspend is enough to keep things going, and it was turned into workaround, as explained below. Quote from original descriprion: The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In USB 2.0 Host controllers, each EHCI controller has one or more companion controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will contain one or more ports. For each port, only one of the controllers is connected at any one time. In the 440EPx, there is only one OHCI companion controller, and only one USB 2.0 Host port. All ports on an USB 2.0 controller default to the companion controller. If you load only an ohci driver, it will have control of the ports and any deviceplugged in will operate, although high speed devices will be forced to operate at full speed. When an ehci driver is loaded, it explicitly takes control of the ports. If there is a device connected, and / or every time there is a new device connected, the ehci driver determines if the device is high speed or not. If it is high speed, the driver retains control of the port. If it is not, the driver explicitly gives the companion controller control of the port. The is a software workaround that uses Initial version of the software workaround was posted to linux-usb-devel: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html and later available from amcc.com: http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2 The patch below is generally based on the latter, but reworked to powerpc/of_device USB drivers, and uses a few devicetree inquiries to get rid of (some) hardcoded defines.

| * powerpc/86xx: Update 8641hpcn dts file to match latest u-bootBecky Bruce2008-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The newest revision of uboot reworks the memory map for this board to look more like the 85xx boards. Also, some regions which were far larger than the actual hardware have been scaled back to match the board, and the imaginary second flash bank has been removed. Rapidio and PCI are mutually exclusive in the hardware, and they now are occupying the same space in the address map. The Rapidio node is commented out of the .dts since PCI is the common use case.

So far all devices are detected as OF device. A notifier function is used to set the dma_ops for the of_platform bus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch the L2 cache is enabled on Canyonlands to increase the overall performance. There is a known cache coherency issue with the L2 cache, but this is related to the high bandwidth (HB) PLB segment where the memory address is 0x8.xxxx.xxxx (low bandwidth PLB segment is mapped to 0x0.xxxx.xxxx). Since this HB address is currently unused it is safe to enable the L2 cache. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

The patch includes changes to the Bamboo and Canyonlands device-trees to add such a hole, others can be updated separately. The ISA memory hole is an additional outbound window configured in the bridge to generate PCI cycles in the low memory addresses, thus allowing to access things such as the hard-decoded VGA aperture at 0xa0000..0xbffff or other similar things. It's made accessible to userspace via the new legacy_mem file in sysfs for which support was added by a previous patch.

* | powerpc: Revert CHRP boot wrapper to real-base = 12MB on 32-bitPaul Mackerras2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9b09c6d909dfd8de96b99b9b9c808b94b0a71614 ("powerpc: Change the default link address for pSeries zImage kernels") changed the real-base value in the CHRP note added by addnote to the zImage from 12MB to 32MB. It turns out that this causes unnecessary extra reboots on old 32-bit CHRP machines. This therefore adds a -r flag to addnote to allow us to specify what real-base value it should put in the CHRP note, and adjusts the wrapper script to pass -r c00000 to addnote when making a zImage for a CHRP machine. Also, CHRP machines ignore the RPA note, so we don't need to arrange for it to be the same as the kernel's.

* | powerpc: Fix boot wrapper memcmp() called with zero length argumentMike Ditto2008-10-21
| | | | | | | | | | | | | | | | | | I noticed, when trying to use, e.g., node = find_node_by_prop_value(prev, "booleanprop", "", 0)) to search for all nodes with a certain boolean property, that memcmp() returns garbage when comparing zero bytes. It should return zero. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* | powerpc/boot: Compare _start against ei.loadsize instead ei.memsizeSebastian Siewior2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the vmlinux binary in memory is larger than 4 MiB than it collides with the initial boot code which is linked at 4 MiB in case of cuBoot. If the the uncompressed image size (on disk size) is less than 4 MiB then it would fit. The difference between those two sizes is the bss section. In cuBoot we have the dtb embedded right after the data section so it is very likely that the reset of the bss section (in kernel's start up code) will overwrite the dtb blob. Therefore we reallocate the dtb. Something similar is allready done to the initrd.
