[POWERPC] Start removing linux,network-index in favour of aliases

2008-03-26T12:19:16Z

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. Signed-off-by: David Gibson Signed-off-by: Josh Boyer

[POWERPC] 4xx: EP405 boards support for arch/powerpc

2007-12-23T19:13:14Z

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 Signed-off-by: Josh Boyer

[POWERPC] Use embedded libfdt in the bootwrapper

2007-12-11T02:46:14Z

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. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] 4xx: Enable EMAC for PPC405 Walnut board

2007-10-19T21:18:33Z

This patch enables the ibm_newemac driver for the Walnut board. It fixes the device tree for the walnut board to order the MAL interrupts correctly and adds the local-mac-address property to the EMAC node. The bootwrapper is also updated to extract the MAC address from the OpenBIOS offset where it is stored. Signed-off-by: Josh Boyer

[POWERPC] 4xx: Fix timebase clock selection on Walnut

2007-10-19T21:18:31Z

The current bootwrapper fails to set the timebase clock to the CPU clock which causes the time to increment incorrectly. This fixes it by using the correct #define for the CPC0_CR1 register. Signed-off-by: Josh Boyer
