Updated the device trees to have the PCI nodes be at the same level as the SOC node. This is to make it so that the SOC nodes children address space is just on chip registers and not other bus memory as well. Also, for PCIe nodes added a P2P bridge to handle the virtual P2P bridge that exists in the PHB. Signed-off-by:

Removed the following cruft from .dts files: * 32-bit in cpu node -- doesn't exist in any spec and not used by kernel * removed built-in (chrp legacy) * Removed #interrupt-cells in places they don't need to be set * Fixed ranges on lite5200* * Removed clock-frequency from i8259 pic node, not sure where this came from * Removed big-endian from i8259 pic nodes, this was just bogus Signed-off-by:

1. Update the way get_brgfreq() finds things in the device tree. It now uses names that are less namespace polluting. The old names are supported until all boards are converted. 2. "size" is changed from unsigned int to int, to match what of_get_property() expects. Signed-off-by:

1. Fix RTC type - it is a rs5c372a, not rs5c372b 2. Configure both UART interrupts edge-triggered 3. Add a license header to ls_uart.c 4. Check for running on linkstation in a late_initcall() function. Needed for multiplatform builds, even though linkstation doesn't support them yet 5.

Renamed functions in 85xx_ds from 8544 to 85xx. Kept an unique machine def/probe for the MPC8544 DS board to handle some subtle differences between the future board based on the DS platform. Also fixed building w/o CONFIG_PCI and minor whitespace fixes. Signed-off-by:

Currently, the ps3 kernel fails to build without smp but with kexec, as ps3_kexec_cpu_down needs ps3_smp_cleanup_cpu, which isn't defined on UP kernels. This change adds an empty ps3_smp_cleanup_cpu for UP kernels. Booted on ps3. Signed-off-by:

Some versions of PWRficient 1682M have an interrupt controller in which the first register in each pair for interrupt sources doesn't always read with the right polarity/sense values. To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution. Still, keep it under a config option to avoid wasting memory on other platforms. Signed-off-by:

1. ft_create_node was returning the internal pointer rather than a phandle. 2. ft_find_device_rel was treating a "top" phandle of NULL as an error, rather than as the root of the tree. The old, absolute ft_find_device is removed, and the relative version is renamed to ft_find_device(). Signed-off-by:

Add printout of some SoC error status registers, and dump the SLB contents for those machine check events where it makes sense. Since we can't go about and ioremap registers at machine check time, and we generally want to do as little as possible to print out the information, pre-build a table of the registers to dump and their address in the common PCI config space range.

Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch. Signed-off-by:
