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: NJosh Boyer <jwboyer@linux.vnet.ibm.com>

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.

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: NStefan Roese <sr@denx.de> Signed-off-by: NJosh Boyer <jwboyer@linux.vnet.ibm.com>

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: NStefan Roese <sr@denx.de> Signed-off-by: NJosh Boyer <jwboyer@linux.vnet.ibm.com>

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.

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.

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.

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.

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.

lockdep goes off on the iova copy_reserved_iova() because it and a function it calls grabs locks in the from, and the to of the copy operation. The function grab locks of the same lock classes triggering the warning. The first lock grabbed is for the constant reserved areas that is never accessed after early boot. Technically you could do without grabbing the locks for the "from" structure its copying reserved areas from. But dropping the from locks to me looks wrong, even though it would be ok. The affected code only runs in early boot as its setting up the DMAR engines. This patch gives the reserved_ioval_list locks special lockdep classes.

The VIA VT6212 defaults to only waiting 1us between passes over EHCI's async ring, which hammers PCI badly ... and by preventing other devices from accessing the bus, causes problems like drops in IDE throughput, a problem that's been bugging users of those chips for several years. A (partial) datasheet for this chip eventually turned up, letting us see how to make it use a VIA-specific register to switch over to the the normal 10us value instead, as suggested by the EHCI specification Solution noted by Lev A. Melnikovsky. It's not clear whether this register exists on other VIA chips; we know that it's ineffective on the vt8235. So this patch only applies to chips that seem to be incarnations of the (discrete) vt6212. Signed-off-by: NRene Herman <rene.herman@gmail.com> Tested-by: NLev A.
