2007-12-23[POWERPC] 4xx: Change Kilauea PCIe bus ranges in dts fileStefan Roese1-4/+4
Currently we have some limitations in the 4xx PCIe driver and can't support all possible PCIe busses. But the current limits in the dts file are quite low (only 16 busses per RC). This patch increases the number to 64 per RC. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

2007-12-23[POWERPC] 4xx: Rename CPU nodes to avoid dtc incompatibilityJosh Boyer9-18/+27
Recent DTC versions disallow certain special characters in full paths without being quoted with {}. That however breaks compatibility with older DTC versions. Work around this by renaming the CPU nodes for the 4xx files to a generic node name, and specify the processor type in the model property of the CPU node.

2007-12-23[POWERPC] 4xx: Change Kilauea dts to support new EMAC device tree propertiesStefan Roese1-0/+5
The recent changes from Benjamin Herrenschmidt to the ibm_newemac now make it possible to support other 4xx variants by just defining the correct properties in the device tree. In this case of the 405EX we need to define "has-mdio" in the RGMII node and "has-inverted-stacr-oc" and "has-new-stacr-staopc" in the EMAC node same as on the 440EPx.

2007-12-23[POWERPC] 4xx: Add 440SPe revA runtime detection to PCIeStefan Roese1-3/+3
This patch adds runtime detection of the 440SPe revision A chips. These chips are equipped with a slighly different PCIe core and need special/ different initialization. The compatible node is changed to "plb-pciex-440spe" ("A" and "B" dropped). This is needed for boards that can be equipped with both PPC revisions like the AMCC Yucca.

2007-12-23[POWERPC] 4xx: remove bogus "ranges" property in Bamboo EBC nodeBenjamin Herrenschmidt1-1/+0
This removes a bogus empty "ranges" property in the EBC device node of the Bamboo board device-tree. The "ranges" property should be created by the wrapper code when it is implemented. Until then, remove the empty property since it incorrectly implies that there is a 1:1 address mapping between the EBC and the OPB. This also fixes a warning from newer DTCs.

2007-12-23[POWERPC] 4xx: Rework clock probing in boot wrapperBenjamin Herrenschmidt7-135/+233
This reworks the boot wrapper library function that probes the chip clocks. Better separate the base function that is used on 440GX,SPe,EP,... from the uart fixups as those need different device-tree path on different processors. Also, rework the function itself based on the arch/ppc code from Eugene Surovegin which I find more readable, and which handles one more bypass case. Also handle the subtle difference between 440EP/EPx and 440SPe/GX, on the former, PerClk is derived from the PLB clock while on the later, it's derived from the OPB.

2007-12-23[POWERPC] 4xx: EP405 boards support for arch/powerpcBenjamin Herrenschmidt7-52/+353
Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD comes from a device-tree property, PCI is working to the point where I can see the video card, USB device, and south bridge. This should work with both EP405 and EP405PC. I've not totally figured out how IRQs are wired on this hardware though, thus at this stage, expect only USB interrupts working, pretty much the same as what arch/ppc did. Also, the flash, nvram, rtc and temp control still have to be wired. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

devp_offset_find() Many operations, as currently used in the wrapper, assume they can pass NULL and have it be treated as the root node. However, libfdt-wrapper converts NULL to -1, which is only appropriate when searching for nodes, and will cause an error otherwise.

This incorporates libfdt (from the source embedded in an earlier commit) into the wrapper.a library used by the bootwrapper. This includes adding a libfdt_env.h file, which the libfdt sources need in order to integrate into the bootwrapper environment, and a libfdt-wrapper.c which provides glue to connect the bootwrapper's abstract device tree callbacks to the libfdt functions. In addition, this changes the various wrapper and platform files to use libfdt functions instead of the older flatdevtree.c library.

It should do that in the same directory as the output, not the directory where the wrapper objects are kept (which might potentially not be writable when the script runs).
