2007-10-03[POWERPC] bootwrapper: Add PlanetCore firmware supportScott Wood3-1/+216
This is a library that board code can use to extract information from the PlanetCore configuration keys. PlanetCore is used on various boards from Embedded Planet.

2007-09-28[POWERPC] mpc8349emitx.dts: Setup USB-DR for peripheral mode.jacmet@sunsite.dk1-0/+1
Setup dr_mode for USB-DR to peripheral as the default (host mode) doesn't make much sense for the mini-AB connector on the ITX board. Peripheral mode is preferable to OTG as the fsl_usb2_udc.c driver doesn't yet properly support it.

2007-09-14[POWERPC] MPC832x_RDB: Update dts to use SPI1 in QE, register mmc_spi stubAnton Vorontsov1-1/+1
Enabled using SPI controller on the MPC832x RDB board. We currently use a modalias of "spidev" as a place holder (replace with "mmc_spie") until the mmc_spi driver support is merged in. This gets us the ability to test SPI until then. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-09-14[POWERPC] Move PCI nodes to be sibilings with SOC nodesKumar Gala16-1285/+1323
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: Kumar Gala <galak@kernel.crashing.org>

2007-09-14[POWERPC] bootwrapper: Only print MAC addresses when the node is actually presentScott Wood1-4/+6
Some firmwares (such as PlanetCore) only provide a base MAC address, and expect the kernel to set certain bits to generate the addresses for the other ports. As such, MAC addresses are generated that may not correspond to actual hardware.

2007-09-14[POWERPC] bootwrapper: flatdevtree fixesScott Wood3-27/+23
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().

2007-08-22[POWERPC] bootwrapper: serial_console_init() fixesScott Wood1-7/+5
1. Search the entire compatible list for serial devices. The serial code previously did a simple strcmp on the compatible node; this fails when the match string is not the first compatible listed.

2007-08-22[POWERPC] bootwrapper: Add TARGET_HAS_ETHn tests to ppcboot.hScott Wood1-3/+4
U-boots more recent than when ppcboot.h was forked allow the board config file to enable additional ethernet ports explicitly, rather than using a hardcoded list of targets. This allows bootwrapper platform files to do the same. Fortunately, nothing after the ethernet addresses is of interest to cuboot platforms, so the inevitable mismatches won't be too catastrophic.

2007-08-22[POWERPC] bootwrapper: dt_xlate_range() bugfixesScott Wood1-7/+13
1. The check whether ranges fits in the buffer was using elements rather than bytes. 2. Empty ranges were not properly treated as transparent, and missing ranges were treated as transparent. 3. The loop terminated when translating from the root rather than to. Once bug #2 was fixed, it failed due to a missing ranges in the root node. 4. In decoding the ranges property, the #size-cells used was that of the parent, not the child.

2007-08-17[POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boardsKumar Gala2-138/+64
The interrupt routing in the device trees for the ULI M1575 was inproperly using the interrupt line field as pci function. Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

2007-08-17[POWERPC] Fixes to allow use of Ebony's flash chips through physmap_ofDavid Gibson2-0/+40
This patch contains a handful of small fixes to allow the Ebony's flash to be exposed as MTD devices via the physmap_of driver. Specifically it: - Makes a small addition to the device tree and zImage wrapper to record the correct address for the flash in the device tree based on the board switches as reported via an FPGA register. - Prohibits building the old hard-coded "Ebony" flash map on arch/powerpc kernels, in favour of using physmap_of's device tree based approach. - Enables MTD and physmap_of in the Ebony defconfig.
