The stolen time calculation (per comment within the code) doesn't need the half-jiffy stagger any more. There isn't an issue with bouncing off global locks, so we really shouldn't need any sort of staggering at all. However, the last_jiffy value still needs to be set. This removes the extra stagger logic, and just sets the values. This change should benefit applications that rely on barrier synchronization, and will help cut down OS jitter.

The resulting zImage will be arch/powerpc/boot/zImage.dts. and arch/powerpc/boot/zImage.dts_initrd., respectively. Having separate rules allows the user to choose whether to include a device tree--and which device tree--at build time. This is useful when one Makefile target builds a zImage that runs on several platforms except for differing device trees. By just setting CONFIG_DEVICE_TREE and running "make zImage.dts" the exact zImage you want is built without Makefile bloat or manually running the wrapper script. The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE) Signed-off-by: Mark A.

Unfortunately, the firmware on some of mv64x60-based platforms do not properly or completely configure those windows (e.g., MPSC->system memory windows not configured or CPU->PCI MEM space not configured). So, the missing configuration needs to be done in either the bootwrapper or in the kernel. To keep the kernel as clean as possible, it is done in the bootwrapper. Note that I/O controller configuration is NOT being done, its only the windows to allow the I/O controllers and other components to access memory, etc. that is being done--drivers assume that their controllers can already access system memory). Table of routines and the windows they configure: mv64x60_config_ctlr_windows() ENET->System Memory MPSC->System Memory IDMA->System Memory mv64x60_config_pci_windows() PCI MEM->System Memory PCI I/O->Bridge's Registers mv64x60_config_cpu2pci_window() CPU->PCI MEM CPU->PCI I/O Signed-off-by: Mark A.

Greer" Date: Sat, 12 May 2007 10:54:53 +1000 Subject: [PATCH 14/23] [POWERPC] Add bootwrapper support for Marvell/mv64x60 I2C Some platforms support a variety processor modules with no method of determining which exact processor module is being used except by examining Vital Product Data (VPD). The modules may have different amounts of memory, clock frequencies, etc. so reading the VPD becomes necessary to correctly set properties in the device tree before its passed to the kernel. Often the VPD is stored in I2C EEPROMs so an I2C driver becomes necessary. This I2C driver is for the I2C controller that's embedded on the Marvel mv64x60 line of host bridges. Signed-off-by: Mark A.

This driver (like the other mv64x60 drivers) are unusual in that it works on both the MIPS and PowerPC architectures. Because of that, the drivers do not support the normal PowerPC of_platform_bus_type. They support platform_bus_type instead.

Greer" Date: Sat, 12 May 2007 10:58:18 +1000 Subject: [PATCH 22/23] [POWERPC] Add bootwrapper support for Motorola PrPMC2800 platform The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or PrPMC2800 baseboard, respectively. There are several variants of each type of processor module which can have different amounts of memory, amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362. The bootwrapper code for that platform reads VPD from an I2C EEPROM to determine the processor module variant. From the variant, the amount of memory, etc. is determined and the device tree is updated accordingly. If the variant cannot be determined (e.g., corrupted VPD or a previously unknown variant), the property values already in the device tree are used. Also, the firmware for those platforms does not completely configure the mv64x60 host bridge so that configuration is done here. Signed-off-by: Mark A.

From fd4ba7e2b7ce9a48b8c60d5fcd65feda5746812e Mon Sep 17 00:00:00 2001 From: Dale Farnsworth Date: Sat, 12 May 2007 10:58:43 +1000 Subject: [PATCH 23/23] [POWERPC] Add arch/powerpc support for the Motorola PrPMC2800 This finally adds the PPC_PRPMC2800 Kconfig option, the board setup code (the setup and reset functions) and the defconfig, to support the Motorola PrPMC2800 platform.
