This patch adds support for the 256k L2 cache found on some IBM/AMCC 4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c) which currently "only" adds the L2 cache init code. Other common 4xx stuff can be added later here. The L2 cache handling code is a copy of Eugene's code in arch/ppc with small modifications. Tested on AMCC Taishan 440GX. Signed-off-by:

Currently Haleakala uses the Kilauea platform code. This patch adds "haleakala" to the compatible property, in case later kernel versions will introduce a Haleakala platform code. Signed-off-by:

The patch adds the Glacier dts. The Glacier is nearly identical to the Canyonlands (460EX). Here the differences: - 4 ethernet ports instead of 2 - no SATA port - no USB port Signed-off-by:

It appears that in some cases, the sync word might not be recognized by the hardware correctly. If this happens, then attempting to read from the port results in an unrecoverable error because of the design of the FPGA core. This patch updates the code to check the status of the device before reading the IDCODE, in order to avoid entering this unrecoverable state. This patch also adds additional NOOP commands into the sychronization sequence, which appears to be necessary to avoid the condition on some hardware. Signed-off-by:

Both the buffer-based and fifo-based icap cores have a status register. Previously, this was only used internally to check whether transactions have completed. However, the status can be useful to the main driver as well. This patch exposes these status functions to the main driver along with some masks for the differnet bits. Signed-off-by:

This patch adds TAH (TCP/IP Acceleration Hardware) support to the taishan 440GX dts. It depends on the NEWEMAC/tah patch that adds the compatible "ibm,tah" property to the matching table. Signed-off-by:

The AMCC 440EP Yosemite board is very similar to the original AMCC Bamboo board. This adds a YOSEMITE option to Kconfig, and reuses the existing bamboo board support in the kernel. Signed-off-by: -

All this code is needed to properly initialize the 460EX PCIe host bridge(s). We re-initialize all ports again, even though this has been done in the bootloader (U-Boot) before. This way we make sure, that we always run the latest init code in Linux and don't depend on code versions from U-Boot. Unfortunately all IBM/AMCC chips currently supported in this PCIe driver need a different reset-/init-sequence. Tested on AMCC Canyonlands eval board. Signed-off-by:

Canyonlands is the AMCC 460EX eval board, featuring nearly all of the 460EX interfaces: - 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane) - 2 * GBit Ethernet with TCP/IP acceleration - USB 2.0 Host/Device OTG and Host interface - SATA port Signed-off-by:

This patch adds basic support for the AMCC 460EX/460GT PPC's to arch/powerpc. Currently those PPC's are still based on a 440 core and *not* a 460 core. Here some basic features of those SoC's: 460EX: - Up to 1.2GHz, 32kB L1 I-cache and D-cache, 256kB L2-cache, FPU - 1 * PCI (max 66MHz), 2 * PCIe (one 4-lane, one 1-lane) - 2 * GBit Ethernet with TCP/IP acceleration - USB 2.0 Host/Device OTG and Host interface - SATA controller - Optional security feature 460GT (only changes to 460EX): - 4 * GBit Ethernet with TCP/IP acceleration - RapidIO - No SATA - No USB Signed-off-by:

This patch alters the bootwrapper for a number of machines (roubhly all 4xx based cuboot or treeboot platforms) to use aliases instead of the linux,network-index hack to work out which MAC address to attach to which ethernet device node. The now obsolete linux,network-index properties are removed from the corresponding device trees. This won't break backwards compatiblity, because in cases where this fixup code is relevant, the device tree is part of the kernel image. The references to linux,network-index are removed from booting-without-of.txt. Not only is it now deprecated, but as a hack applicable only when the device tree blob and fixup code were in the same image, this property never belonged in booting-without-of.txt which describes the interface between the kernel and firmware or bootloaders which produce a device tree. By the time the device tree reaches the kernel, all the MAC addresses must be fully filled in. Signed-off-by:

scanlog_init() could use some love. * properly return -ENODEV if this system doesn't support scan-log-dump * don't printk if scan-log-dump not present; only older systems have it * convert from create_proc_entry() to preferred proc_create() * allocate zeroed data buffer * fix potential memory leak of ent->data on failed create_proc_entry() * simplify control flow Signed-off-by:

This adds /sys/kernel/phyp_dump_active so that kdump init scripts may look for it and take appropriate action if this file is found. This file is only created when phyp_dump has been registered. Signed-off-by:

This adds a kernel command line option "phyp_dump", which takes a 0/1 value for disabling/ enabling phyp_dump at boot time. Kdump can use this on cmdline (phyp_dump=0) to disable phyp-dump during boot when enabling itself. This will ensure only one dumping mechanism is active at any given time. Signed-off-by:

Check to see if there actually is data from a previously crashed kernel waiting. If so, allow user-space tools to grab the data (by reading /proc/kcore). When user-space finishes dumping a section, it must release that memory by writing to sysfs. For example, echo "0x40000000 0x10000000" > /sys/kernel/release_region will release 256MB starting at the 1GB. The released memory becomes free for general use. Signed-off-by:

The hypervisor can look at the value in the wait_state_cycles field of the VPA for an estimate of how busy dedicated processors are. Currently, as the kernel never touches this field, we appear to be 100% busy. This records the duration the kernel is in powersave and passes that to the HV to provide a reasonable indication of utilisation. Signed-off-by:

Prevailing practice for define_machine() in powerpc is to use the platform name when the platform has only one define_machine() statement, but maple uses "maple_md". This caused me some head-scratching when writing some new code that uses machine_is(maple). Use "maple" instead of "maple_md". There should not be any behavioral change -- fixup_maple_ide() calls machine_is(maple) but the body of the function is ifdef'd out. Signed-off-by:
