* MIPS: Malta: Fixup rebootPaul Burton2016-11-041-1/+2
| | | | | | | | | | | | | | | | | | | | Commit 10b6ea0959de ("MIPS: Malta: Use syscon-reboot driver to reboot") converted the Malta board to use the generic syscon-reboot driver to handle reboots, but incorrectly used the value 0x4d rather than 0x42 as the magic to write to the reboot register. I also incorrectly believed that syscon/regmap would default to native endianness, but this isn't the case. Force this by specifying with a native-endian property in the devicetree.

* MIPS: generic: Convert SEAD-3 to a generic boardPaul Burton2016-10-062-1/+2
| | | | | | | | | | | | | | | | | | | | | Convert the MIPS SEAD-3 board support to be a generic board, supported by generic kernels. Because the SEAD-3 boot protocol was defined long ago and we don't want to force a switch to the UHI protocol, SEAD-3 is added as a legacy board which is detected by reading the REVISION register. This may technically not be a valid memory read & future work will include attempting to handle that gracefully. In practice since SEAD-3 is the only legacy board supported by the generic kernel so far the read will only happen on SEAD-3 boards, and even once Malta is converted the same REVISION register exists there too. Other boards such as Boston, Ci20 & Ci40 will use the UHI boot protocol & thus not run any of the legacy board detect functions.

* MIPS: generic: Introduce generic DT-based board supportPaul Burton2016-10-061-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a "generic" platform, which aims to be board-agnostic by making use of device trees passed by the boot protocol defined in the MIPS UHI (Universal Hosting Interface) specification. Provision is made for supporting boards which use a legacy boot protocol that can't be changed, but adding support for such boards or any others is left to followon patches. Right now the built kernels expect to be loaded to 0x80100000, ie. in kseg0. This is fine for the vast majority of MIPS platforms, but nevertheless it would be good to remove this limitation in the future by mapping the kernel via the TLB such that it can be loaded anywhere & map itself appropriately. Configuration is handled by dynamically generating configs using scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc makes use of it. This allows for variations upon the configuration, eg. differing architecture revisions or subsets of driver support for differing boards, to be handled without having a large number of defconfig files.

* MIPS: Support generating Flattened Image Trees (.itb)Paul Burton2016-10-061-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for generating kernel images in the Flattened Image Tree (.itb) format as supported by U-Boot. This format is essentially a Flattened Device Tree binary containing images (kernels, DTBs, ramdisks) and configurations which link those images together. The big advantages of FIT images over the uImage format are: - We can include FDTs in the kernel image in a way that the bootloader can extract it & manipulate it before providing it to the kernel. Thus we can ship FDTs as part of the kernel giving us the advantages of being able to develop & maintain the DT within the kernel tree, but also have the benefits of the bootloader being able to manipulate the FDT. Example uses for this would be to inject the kernel command line into the chosen node, or to fill in the correct memory size. - We can include multiple configurations in a single kernel image. This means that a single FIT image can, given appropriate bootloaders, be booted on different boards with the bootloader selecting an appropriate configuration & providing the correct FDT to the kernel. - We can support a multitude of hashes over the data.

| | | | | | | | | | | | | | | | | | | | | | | | Probe the UARTs on SEAD3 boards using device tree rather than platform code, in order to reduce the amount of the latter. This requires that CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig. The SEAD3 DT shim code is extended to read bootloader environment variables to determine the appropriate UART & mode for kernel console output & set the stdout-path property of the chosen node accordingly. In contrast to the old platform code, which appears to have only ever set "console=ttyS0,38400n8r" with the code in console_config never having an effect, this will honor the "yamontty" environment variable to select between the 2 UARTs on the board and then check the "modetty0" or "modetty1" variable as appropriate to determine the UART configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | Probe the CPU interrupt controller & optional Global Interrupt Controller (GIC) using devicetree rather than platform code. Because the bootloader on SEAD3 does not provide a device tree to the kernel & the device tree is always built in, we patch out the GIC node during boot if we detect that a GIC is not present in the system. The appropriate IRQ domain is discovered by platform code setting up device IRQ numbers temporarily. It will be removed by further patches which move the devices towards being probed via device tree. No behavioural change is intended by this patch.

| | | | | | | | | | | | | | | | | | | The DT fragment will select the ohci-platform driver, since that can handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based board with anything connected to the USB host controller, I did test the generic OHCI driver successfully on a JZ4770-based board. The device is disabled by default; boards that want to use it can override the "status" property. The mass-production Qi LB60 boards don't use the USB host controller.

* MIPS: tools: Add relocs toolMatt Redfearn2016-05-136-0/+861
| | | | | | | | | | | | | | | | | | | | | | | This tool is based on the x86/boot/tools/relocs tool. It parses the relocations present in the vmlinux elf file, building a table of relocations that will be necessary to run the kernel from an address other than its link address. This table is inserted into the vmlinux elf, in the .data.relocs section. The table is subsequently used by the code in arch/mips/kernel/relocate.c (added later) to relocate the kernel. The tool, by default, also marks all relocation sections as 0 length. This is due to objcopy currently being unable to handle copying the relocations between 64 and 32 bit elf files as is done when building a 64 bit kernel.
