* powerpc/dts: add eSDHC compatible listYangbo Lu2015-06-015-0/+5

* powerpc: Remove the celleb supportMichael Ellerman2015-04-071-2/+0
| | | | | | | | | | | | | | | | | The celleb code has seen no actual development for ~7 years. We (maintainers) have no access to test hardware, and it is highly likely the code has bit-rotted. As far as we're aware the hardware was never widely available, and is certainly no longer available, and no one on the list has shown any interest in it over the years. So remove it. If anyone has one and cares please speak up. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Jeremy Kerr <jk@ozlabs.org>

* powerpc/boot: don't clobber r6 and r7 in epapr bootJeremy Kerr2015-03-161-12/+12
| | | | | | | | | | | We use r6 and r7 for epapr boot, but the current pre-C init will clobber both of these. This change does a simple replacement, of r6 -> r12 and r7 -> r13, so that we hit platform init with these registers intact.

* powerpc/boot: Fix stack corruption in epapr entry pointJeremy Kerr2015-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, a 64-bit little-endian zImage.epapr won't boot in epapr mode, as we never return from platform_init. Before entering C, we initialise our stack by setting r1 16 bytes below the end of the _bss_stack: stwu r0,-16(r1) /* establish a stack frame */ However, the called function will save the caller's lr in the caller's frame's lr save area, at -16(r1) to -32(r1). This means that writes to the fdt variable will corrupt the saved link register: 0000000020c06018 l O .bss 0000000000001000 _bss_stack 0000000020c07018 l O .bss 0000000000000008 fdt We'll need at least 32 bytes in the initial stack frame, to handle the LR save area. We bump this to 112 bytes, as that'll be the max required by ABIv1. Thanks to Alistair Popple for debugging help.

* powerpc/boot/wrapper: use the pseries wrapper for zImage.epaprJeremy Kerr2015-03-161-1/+1
| | | | | | | | | | | | We'll likely be entering the zImage.epapr as BE, so include the pseries implementation of _zimage_start, which adds the endian fixup magic. Although the endian fixup won't work on Book III-E machines starting LE, the current entry point doesn't support LE anyway, so we shouldn't be breaking anything.

* powerpc/boot/fdt: Add little-endian support to libfdt wrappersJeremy Kerr2015-03-162-6/+16
| | | | | | | | | | For epapr-style boot, we may be little-endian. This change implements the proper conversion for fdt*_to_cpu and cpu_to_fdt*. We also need the full cpu_to_* and *_to_cpu macros for this.

Run the loop at least once to let the user stop the boot by holding a key pressed. If the timeout is set to 0, don't wait for input, which can be used as a workaround if the boot hangs on random data coming in on the serial port.

The biggest series, also aimed at -stable, is from Aneesh and is the result of weeks and weeks of debugging to find out why the heck or THP implementation was occasionally triggering multi-hit errors in our level 1 TLB. It ended up being a combination of issues including subtleties as to how we should invalidate those special 'MPSS' pages we use to allow the use of 16M pages inside 4K/64K "base page size" segments (you really have to love our MMU !) Another interesting one in the "OMG" category is the series from Michael adding memory barriers to spin_is_locked(). That's also the result of many days of debugging to figure out why the semaphore code would occasionally crash in ways that made no sense. It ended up being some creative lock stacking that was defeated by the fact that our locks allow a load inside the locked section to be re-ordered with the load of the lock value itself (I'm still of two mind about whether to kill that once and for all by putting a heavier barrier back into our lock implementation...).

| | | | | | | | | | | | | | | | | | | | | | | | The rule to create the final images uses a zImage.% pattern. Unfortunately, this also matches the names of the zImage.*.lds linker scripts, which appear as a dependency of the final images. This somehow worked when $(srctree) used to be an absolute path, but now the pattern matches too much. List only the images from $(image-y) as the target of the rule, to avoid the circular dependency.

It got a bit delayed in part because I wasn't paying attention, and in part because I discovered I had a core PCI change without a PCI maintainer ack in it. Bjorn eventually agreed it was ok to merge it though we'll probably improve it later and I didn't want to rebase to add his ack. There is going to be a bit more next week, essentially fixes that I still want to sort through and test. The biggest item this time is the support to build the ppc64 LE kernel with our new v2 ABI. We previously supported v2 userspace but the kernel itself was a tougher nut to crack. This is now sorted mostly thanks to Anton and Rusty. We also have a fairly big series from Cedric that add support for 64-bit LE zImage boot wrapper. This was made harder by the fact that traditionally our zImage wrapper was always 32-bit, but our new LE toolchains don't really support 32-bit anymore (it's somewhat there but not really "supported") so we didn't want to rely on it. This meant more churn that just endian fixes. This brings some more LE bits as well, such as the ability to run in LE mode without a hypervisor (ie. under OPAL firmware) by doing the right OPAL call to reinitialize the CPU to take HV interrupts in the right mode and the usual pile of endian fixes. There's another series from Gavin adding EEH improvements (one day we *will* have a release with less than 20 EEH patches, I promise!). Another highlight is the support for the "Split core" functionality on P8 by Michael. This allows a P8 core to be split into "sub cores" of 4 threads which allows the subcores to run different guests under KVM (the HW still doesn't support a partition per thread). And then the usual misc bits and fixes ..." [ Further delayed by gmail deciding that BenH is a dirty spammer.
