It makes head_64.S a bit more readable and will allow us to move the iSeries exceptions elsewhere. This also removes the last line of the comment: * The following macros define the code that appears as * the prologue to each of the exception handlers. They * are split into two parts to allow a single kernel binary * to be used for pSeries and iSeries. * LOL. One day... - paulus Anything is possible. :-) Signed-off-by:

Rework timebase handoff to play nice with configurations with more than 2 cores, as well as with CPU hotplug. Previous scheme just pushed out the current timebase from the giving core to all cores without caring if they wanted it or not, nor checking if they'd taken it. The taking side didn't make sure the giving side had provided a value yet either. In other words, it was completely broken. Signed-off-by:

This allows booting on legacy, non-device-tree aware versions of U-boot. It also fixes up the hardware to match the PCI and chipselect information in the device tree, as u-boot is inconsistent in setting these up correctly (or at all). Signed-off-by:

This serial port is used on all 8xx, many 82xx, and some 85xx chips. The driver requires that the port has already been set up by the firmware and/or platform code. Signed-off-by:

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. Use dt_is_compatible() instead. 2. Don't call serial_edit_cmdline if getc isn't defined. Signed-off-by:

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.

This can be used rather than doing a simple strcmp, which will fail to handle multiple compatible entries. Signed-off-by:

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. Signed-off-by:

The current code assumes "foo-bar" must always be compatible with a node compatible with "foo", which breaks device trees where this is not so. The "case" part is also wrong according to Open Firmware, but it's more likely to have drivers and/or device trees depending on it, and thus needs to be handled more carefully. Signed-off-by:

We need to have xLparMap in head_64.S so that it is at a fixed address (because the linker will not resolve (address & 0xffffffff) for us). But the assembler miscalculates the KERNEL_VSID() expressions. So put the confusing expressions into asm-offsets.c. Signed-off-by:

The built-in IDE controller is configured in legacy mode, but the PCI registers advertise native mode. Force the PCI class into legacy mode. This allows pata_via to access two drives. The Pegasos specific irq enforcement in the via82cxxx driver must stay because there is apparently no generic way to setup irq per channel. Tested on Pegasos2 with firmware version 20040810, and two IDE disks. Signed-off-by:

At present the cascade interrupt handler for the UIC (interrupt controller on 4xx embedded chips) will misbehave badly if it is called spuriously - that is if the handler is invoked when no interrupts are asserted in the child UIC. Although spurious interrupts shouldn't happen, it's good to behave robustly if they do. This patch does so by checking for and ignoring spurious interrupts. Signed-off-by:

At present the driver for the UIC (the embedded interrupt controller in 4xx chips) uses the handle_level_irq() flow handler. It turns out this does not correctly handle level triggered interrupts on the UIC. Specifically, acknowledging an irq on the UIC (i.e. clearing the relevant bit in UIC_SR) will have no effect for a level interrupt which is still asserted by the external device, even if the irq is already masked. Therefore, unlike handle_level_irq() we must ack the interrupt after invoking the ISR (which should cause the device to stop asserting the irq) instead of acking it when we mask it, before the ISR. This patch implements this change, in a new handle_uic_irq(), a customised irq flow handler for the UIC. For edge triggered interrupts, handle_uic_irq() still uses the old flow - we must ack edge triggered interrupt before the ISR not after, or we could miss a second event which occurred between invoking the ISR and acking the irq.

The UIC (interrupt controller in 4xx embedded CPUs) driver currently missets the IRQ_lEVEL flag in desc->status, due to a thinko. This patch fixes the bug. Currently this is only a cosmetic problem (affects the output in /proc/interrupts), however subsequent patches will use the IRQ_LEVEL flag to affect flow handling. Signed-off-by:
