The xilinxfb driver is improperly casting a physical address to a u32, and the probe routine isn't as straight forward as it could be. (discovered by gcc spitting out warnings on most recent change to xilinxfb driver). This patch fixes the cast and simplifies the probe path. Signed-off-by:

Without this clobber, mtspr can be re-ordered by gcc vs. surrounding memory accesses. While this might be ok for some cases, it's not in others and I'm not confident that all callers get it right (In fact I'm sure some of them don't). So for now, let's make mtspr() itself contain a memory clobber until we can audit and fix everything, at which point we can remove it if we think it's worth doing so. Signed-off-by: -

commit 5b7c3c91 introduced an invalid construct in our CPU selection. This caused warnings, though it still appeared to do the right thing. This fixes it properly by having separate formal definitions of PPC_BOOK3S_32 and PPC_BOOK3S_64 and one statement defining PPC_BOOK3S based on the two above. Signed-off-by:

Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by:

The macro spin_event_timeout() takes a condition and timeout value (in microseconds) as parameters. It spins until either the condition is true or the timeout expires. It returns the result of the condition when the loop was terminated. This primary purpose of this macro is to poll on a hardware register until a status bit changes. The timeout ensures that the loop still terminates if the bit doesn't change as expected. This macro makes it easier for driver developers to perform this kind of operation properly. Signed-off-by:

Some XPedite52xx boards have a legacy boot loader requiring some special care in the boot wrapper. The use of cuboot-85xx is needed to fix up embedded device trees, and a custom link address is specified to accommodate the boot loader and larger kernel image sizes used on X-ES MPC85xx platforms.

Some MPC85xx platforms do support 4 ethernet ports, so make sure the boot wrapper fixes up all of them in the fdt. Since MAC addresses are at the end of the bd_t structure there is no harm in expanding to support 4 MAC address on older 85xx systems that might not have that many. Signed-off-by:

usb0 and usb1 mux settings in the sicrl register were swapped (twice!) in mpc834x_usb_cfg(), leading to various strange issues with fsl-ehci and full speed devices. The USB port config on mpc834x is done using 2 muxes: Port 0 is always used for MPH port 0, and port 1 can either be used for MPH port 1 or DR (unless DR uses UTMI phy or OTG, then it uses both ports) - See 8349 RM figure 1-4.. mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit positions of the usb0 / usb1 mux settings swapped. It would basically work if you specified port1 instead of port0 for the MPH controller (and happened to use ULPI phys), which is what all the 834x dts have done, even though that configuration is physically invalid. Instead fix mpc8349_usb_cfg() and adjust the dts files to match reality. Signed-off-by:

The current device tree for the MPC8272ADS assumes a mapping of 32 MB of NOR flash at 0xFE00.0000, while there are actually only 8 MB on the boards, mapped at 0xFF80.0000. When booting an uImage with such a device tree, the kernel crashes because 0xFE00.0000 is not mapped. Also introduce aliases for serial[01] and ethernet[01]. Signed-off-by:

We determine if we need to enable swiotlb based on how much memory is in the board and if it exceeds 4G or what we can map via PCI inbound windows. Signed-off-by: -

This is the final bit of code to allow enabling swiotlb on mpc86xx. The platform-specific code is very small and consists of enabling SWIOTLB in the config file, registering the swiotlb_setup_bus_notifier initcall, and setting pci_dma_ops to point to swiotlb_pci_dma_ops if we have more memory than can be mapped by the inbound PCI windows.

Add support for caching, to reduce FLASH wear when writing using small blocksizes. As we also don't care anymore about heads and tails in case of partial writes, this greatly simplifies the code for handling writes. Note: We don't bother caching reads smaller than the FLASH chunk size (256 KiB). Signed-off-by:

Currently the FLASH database is updated by the kernel using file operations, meant for userspace only. While this works for us because copy_{from,to}_user() on powerpc can handle kernel pointers, this is unportable and a bad example. Replace the file operations by callbacks, registered by the ps3flash driver. Signed-off-by: -
