* [POWERPC] celleb: Add support for PCI ExpressIshizaki Kou2008-04-245-0/+639
| | | | | | | | | | This adds support for PCI Express port on Celleb. I/O space of this PCI Express port is not mapped in memory space. So we use the io-workaround mechanism to make accesses indirect.

* [POWERPC] Add CONFIG_PPC_PSERIES_DEBUG to enable debugging for platforms/pseriesMichael Ellerman2008-04-249-10/+10
| | | | | | | | | | | | | | | | | | | Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | In pseries/lpar.c, fix some printf specifier mismatches, and add a newline to one printk. In pseries/rtasd.c add "rtasd" to some messages to make it clear where they're coming from. In pseries/scanlog.c remove the hand-rolled runtime debugging support in there. This file has been largely unchanged for eons, if we need to debug it in future we can recompile.

* [POWERPC] Register udbg console early on pseries LPARMichael Ellerman2008-04-241-0/+2
| | | | | | | | | | | | | | On pseries LPAR we can call the udbg routines, and the udbg console very early. So mark the udbg console as safe to call early in boot, and register the udbg console as soon as the udbg routines are hooked up. This allows platforms/pseries code to use printk() and pr_debug() rather than needing to call udbg_printf() directly for early debugging. This is nice because a) it's standard, b) it goes via the printk buffer, and c) you can get printk time stamps.

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>

While the core dumps notes have correct contents, they have the wrong names, as the file descriptors used to generate the note names are off-by-one. An application that opens a SPE context as fd 3, the current core dump code will generate notes like: SPU/4/mem SPU/4/regs etc. This confuses GDB, which knows it is looking for SPE context 3 (from parsing the spu_context_run system call arguments), and cannot find any notes that match context 3. This change corrects the file descriptor counting, to only increment the fd until after we've written the note name.

This trips up if you use "netconsole=foo" on the command line, and has the result that you get _only_ the netconsole, because the hvc device is never added as a preferred console. Worse still if you get the netconsole configuration wrong somehow, you end up with no console at all. As it turns out we don't need to worry about checking the command line. If the user has specified "console=foo", then foo will be set as the preferred console when the command line is parsed in start_kernel(), much later than the pseries code, and so the latter setting will take effect.

Currently we reserve 256MB only. With this change, the code first checks to see if an amount has been specified on the boot command line with the "phyp_dump_reserve_size" option, and if so, uses that much. Otherwise it computes 5% of total ram and rounds it down to a multiple of 256MB, and uses the larger of that or 256MB. This is for large systems with a lot of memory (10GB or more). The aim is to have more space available for the kernel on reboot on machines with more resources. Although the dump will be collected pretty fast and the memory released really early on allowing the machine to have the full memory available, this alleviates any issues that can be caused by having way too little memory on very very large systems during those few minutes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up the pwrficient iommu code a bit. It was using u32 *-based offsets for registers, which can be a bit confusing when comparing to the manual. Generated binaries from the code is unchanged from before.

| * | | | [POWERPC] 4xx: Add idle wait support for 44x platformsJerone Young2008-04-162-1/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the cpu_idle loop for 44x platforms to utilize the Wait Enable feature of the CPU. This helps virtulization solutions know when the guest Linux kernel is in an idle state. A command line option called "idle" is also added to allow people to change the idle loop back to the original variation. This is done by setting "idle=spin" on the kernel command line.

| * | | | [POWERPC] iSeries: Use alternate paca structure for bootingStephen Rothwell2008-04-152-4/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iSeries HV only needs the first two fields of the paca statically initialised, so create an alternate paca that contains only those and switch to our real paca immediately after boot. This is in order to make the 1024 cpu patches easier since they will no longer have to statically initialise the pacas for iSeries.
