2008-10-13powerpc/83xx: don't probe broken PCI on mpc837x_mds boardsAnton Vorontsov
In the standalone setup the board's CPLD disables the PCI internal arbiter, thus any access to the PCI bus will hang the board. The common way to disable particular devices in the device tree is to put the "status" property with any value other than "ok" or "okay" into the device node we want to disable. So, when there is no PCI arbiter on the bus the u-boot adds status = "broken (no arbiter)" property into the PCI controller's node, and so marks the PCI controller as unavailable.

2008-10-13powerpc: make Freescale QE support a selectable Kconfig optionTimur Tabi
Modify the Kconfig so that Freescale QUICC Engine (QE) support is a selectable option, thereby allowing users to compile kernels without any QE support. The drawback is that QE support is now disabled by default on platforms that have a QE, and so a defconfig is needed to enable QE and QE devices (like UCC GETH). Fortunately, all the current relevant defconfigs do that already. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-07-29powerpc/fsl: proliferate simple-bus compatibility to soc nodesKim Phillips
add simple-bus compatible property to soc nodes for 83xx/85xx platforms that were missing them. Add same to platform probe code. This fixes SoC device drivers (such as talitos) to succeed in matching devices present in the soc node. also update mpc836x_rdk dts to new SEC bindings (overlooked in commit 3fd4473: powerpc/fsl: update crypto node definition and device tree instances).

2008-07-16powerpc: pci config cleanupJohn Rigby
Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes.

2008-04-17[POWERPC] 83xx: mpc8315 - fix USB UTMI Host setupAnton Vorontsov
Currently USB Host isn't functional on the MPC8315E boards, for two reasons as described below. MPC8315 Reference Manual says: "The USB DR unit must have the same clock ratio as the encryption core unit, unless one of them has its clock disabled." The encryption core also drives I2C clock, so it is enabled and is equal to 01. That means USBDRCM should be 01 here. Plus, according to MPC8315E-RDB schematics, USB unit consumes CLK_IN clock from the 24.00MHz oscillator, which means we must adjust REFSEL bits as well. p.s. Idially we should rework whole 83xx/usb.c code, in two steps: 1. Move SCCR code to the U-Boot; 2. Implement fsl,usb-clock property in the device tree, so usb.c could decide what clock exactly to use on per-board basis. Though, today we're not in a hurry since there is just one 8315e board out there. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2007-10-08[POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascadingAnton Vorontsov
set_irq_chained_handler overwrites MPIC's handle_irq function (handle_fasteoi_irq) thus MPIC never gets eoi event from the cascaded IRQ. This situation hangs MPIC on MPC8568E. To solve this problem efficiently, QEIC needs pluggable handlers, specific to the underlaying interrupt controller. Patch extends qe_ic_init() function to accept low and high interrupt handlers. To avoid #ifdefs, stack of interrupt handlers specified in the header file and functions are marked 'static inline', thus handlers are compiled-in only if actually used (in the board file). Another option would be to lookup for parent controller and automatically detect handlers (will waste text size because of never used handlers, so this option abolished). qe_ic_init() also changed in regard to support multiplexed high/low lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic() handler implemented appropriately.
