2008-06-10powerpc/sysdev: implement FSL GTM supportAnton Vorontsov1-0/+32
GTM stands for General-purpose Timers Module and able to generate timer{1,2,3,4} interrupts. These timers are used by the drivers that need time precise interrupts (like for USB transactions scheduling for the Freescale USB Host controller as found in some QE and CPM chips), or these timers could be used as wakeup events from the CPU deep-sleep mode. Things unimplemented: 1. Cascaded (32 bit) timers (1-2, 3-4). This is straightforward to implement when needed, two timers should be marked as "requested" and configured as appropriate. 2. Super-cascaded (64 bit) timers (1-2-3-4). This is also straightforward to implement when needed, all timers should be marked as "requested" and configured as appropriate.

2008-04-28fbdev: powerpc: driver for Freescale 8610 and 5121 DIUYork Sun1-0/+33
The following features are supported: plane 0 works as a regular frame buffer, can be accessed by /dev/fb0 plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2 plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4 Special ioctls support AOIs All /dev/fb* can be used as regular frame buffer devices, except hardware change can only be made through /dev/fb0. Changing pixel clock has no effect on other fbs. Limitation of usage of AOIs: AOIs on the same plane can not be horizonally overlapped AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1 AOIs can not beyond phisical display area. Application should check AOI geometry before changing physical resolution on /dev/fb0 required command line parameters to preallocate memory for frame buffer diufb. optional command line parameters to set modes and monitor video=fslfb:[resolution][,bpp][,monitor] Syntax: Resolution xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60 Bpp bpp=32, bpp=24, or bpp=16 Monitor monitor=0, monitor=1, monitor=2 0 is DVI 1 is Single link LVDS 2 is Double link LVDS Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching monirot port for MPC5121ADS has no effect. If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

The Xilinx 16550 uart core is not a standard 16550 because it uses word-based addressing rather than byte-based addressing.

2008-03-26[POWERPC] Start removing linux,network-index in favour of aliasesDavid Gibson1-16/+0
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.

2008-01-09[POWERPC] Xilinx: Update booting-without-of.Stephen Neuendorffer1-23/+33
This now better describes what the UBoot device tree generator actually does. In particular: 1) Nodes have a label derived from the device name, and a node name derived from a generic version of the device type, e.g. 'ethernet', 'serial', etc. 2) Usage of compound nodes (representing more than one device in the same IP) which actually works. This requires having a valid compatible node, and all the other things that a bus normally has. I've chosen 'xlnx,compound' as the bus name to describe these compound nodes. In addition, I've clarified some of the language relating to how mhs nodes should be represent in the device tree.

2007-11-08[POWERPC] Fix cache line vs. block size confusionBenjamin Herrenschmidt1-2/+12
We had an historical confusion in the kernel between cache line and cache block size. The former is an implementation detail of the L1 cache which can be useful for performance optimisations, the later is the actual size on which the cache control instructions operate, which can be different. For some reason, we had a weird hack reading the right property on powermac and the wrong one on any other 64 bits (32 bits is unaffected as it only uses the cputable for cache block size infos at this stage). This fixes the booting-without-of.txt documentation to mention the right properties, and fixes the 64 bits initialization code to look for the block size first, with a fallback to the line size if the property is missing.
