Split the device setup code in ps3_register_repository_device() in two routines: 1. ps3_setup_static_device(), to handle the setup of static devices in the PS3 repository, which can be __init, 2. ps3_setup_dynamic_device(), to handle the setup of storage devices that may appear later in the PS3 repository. This fixes a few section mismatch warnings.

Improve the debugging support of the PS3 bootwraper code: o Increase the size of the PS3 bootwrapper overlay from 256 to 512 bytes to allow for more debugging code in the overlay. o Use the dot symbol to set the size of __system_reset_overlay. The assembler will then emit an error if the overlay code is too big. o Remove some unused instructions. o Update the text describing the PS3 bootwrapper overlay. o Add a check for null pointer writes. o Change hcall return value from s64.

The KSI8560 is a single compact, mid-, or full-size Advanced Mezzanine Card (AdvancedMC™) based on the Freescale™ Semiconductor MPC8560 PowerQUICC III™ microprocessor. This product will serve in data and signaling applications such as signaling gateways (SGW) and softswitch signaling interface cards. The board has altera maxii CPLD, that is used to obtain and manage board configuration. Also there are two SCC UART serial consoles and FCC ethernet, that is routed to the front panel, while other ethernet controlers (TSEC's) are routed to the backplane.

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.

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.

由 David Gibson 提交于
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.
