Provide generic start code that assumes the MMU is off and caches are disabled as per the linux booting protocol for ARMv6 and ARMv7 boards. u-boot image type should be changed to 'linux' for correct behaviour. The new start code builds a minimal "bootstrap" L1PT with cached access disabled and uses the same table for all processors. AP startup is performed in less steps and more code is written in C. The bootstrap tables and stack are placed into an (orphaned) section "_init_memory" which is given to uvm when it is no longer used. Various kernels have been converted to use this code and tested. Some boards were provided by TNF. Thanks! The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS kernels. The GENERIC kernel will also work on RPI2 using u-boot. Thanks to martin@ and aymeric@ for testing on parallella and nanosoc respectively

FDT changes. Untested. Use arm_fdt_cpu_hatch and add mmu entry for DTB Fix exynos5 devmap, bootstrap, and implement early_putchar. Calculate UART frequency based on bootloader config. Fix KERNEL_BASE_PHYS (how did this ever work?) Avoid divide-by-zero for unconfigured PLLs Correctly initialize i2cbus attach args. Add delay and enable mct timecounter. Fix build w/o VERBOSE_INIT_ARM Remove ODROID-U and ODROID-XU kernel configs as they no longer work. - Replace CONSADDR with SSCOM2CONSOLE in example - Remove gtmr (Exynos5422 uses mct) - cinclude EXYNOS.local instead of TEGRA.local Use fdtbus_intr_establish to hook in block interrupts instead of intr_establish. Simplify MCT; just enable it and then attach an ARMv7 generic timer. Add support for building DTB files during kernel build, from christos. build vexpress-v2p-ca15-tc1.dtb with the kernel build tegra124-apalis-eval.dtb, tegra124-jetson-tk1.dtb, tegra124-nyan-big.dtb, tegra124-nyan-blaze.dtb, and tegra124-venice2.dtb with the kernel Allow multiline makeoptions to work by quoting the newline.. Bump for quoting makeoptions with multiple lines. un-c99 bump required config version for multiline makeoptions feature Set DTS makeoption in kernel config Assign DTB files to a variable so we can make -V DTB put the dtb files with their kernels. no need for debug printing. Don't assume that CPU index = GIC CPU interface number. We can determine the current CPU interface number by reading from the read-only GICD_ITARGETSR0 through GICD_ITARGETSR7 registers. This gets interrupts working on Exynos 5422, where the boot processor has GIC CPU interface #4. use -v to get the expanded variable. Use -v to get the expanded variables. Get baud rate from sclk_uartN instead of uartN. Print IRQ number at attach. Fix PLL con0 register locations and add uart clocks Disable exyortc for now, it doesn't work. More or less a rewrite of dwc_mmc, based on awin_mmc, adding DMA support. Update for new dwc_mmc driver Fix dmesg Add Exynos 5410 clock controller driver. Fix a few typos in clock parent names for mmc clocks. From jmcneill@ Update for new dwc_mmc driver Implement platform reset for exynos5 Attach fdtbus to a /clocks node with no compatible string. Add support for ARM Power State Coordination Interface (PSCI). Support interrupt sharing. Add initial support for Allwinner H3 SoC. ARM Trusted Firmware reserves SGIs 8-15 for secure use. Even without ATF, U-Boot on some platforms may use SGIs in this range for the PSCI implementation. Change ARMGIC_IPI_BASE to 0 from (16 - NIPI) and add a compile-time assert to ensure that we don't end up with a conflict. Add H3 MMC support SD/MMC clock fixes Add FDT PHY interface. Add glue for generic ehci/ohci bindings. Rename a variable, NFC. Support parents in different clock domains. Add USB stuff. Doesn't quite work yet. Synopsys DesignWare APB UART needs "options COM_AWIN" for now. Add i2c glue. Add RTC driver. PHY registers start at index 1. Now USB works. Don't allow sharing edge and level triggered interrupts. Add arm_fdt_memory_dump helper for dumping physical addresses from ddb Print clocks with aprint_debug Remove unused defines Add fdtbus_get_string helper Add of_search_compatible, which searches an array of compat_data structures for a matching "compatible" entry matching the supplied OFW node. This allows us to associate data with compatible strings. Add driver for Allwinner Gigabit Ethernet (EMAC) as found in sun8i and later family SoCs. This is a port of my FreeBSD driver which has been confirmed to work on Allwinner H3, A83T, and A64 SoCs. Fix dmesg Add basic support for Allwinner A31. Add basic FDT GPIO support. Fix the pinctrl api to match the spec. A pinctrl config can have more than one xref, and an xref may have specifier data associated with it. Enable sunxi pinctrl support Adjust to new pinctrl API Add P2WI/RSB driver, based on awin_p2wi.c. Fix typo in a compat string. Configure pin defaults at attach No need to explicitly set pinctrl config 0 now Fix some register definitions. Disallow sharing between MPSAFE and non-MPSAFE handlers. Add of_match_compat_data. This routine searches an array of compat_data structures for a matching "compatible" entry matching the supplied OFW node. Add options __HAVE_CPU_UAREA_ALLOC_IDLELWP Add support for reserved memory and MEMORY_DISK_DYNAMIC for FDT-based kernels. the extent code cannot use the full range of u_long, so ignore the last page before 4GB too. ok jmcneill@ Copy install ramdisk to releasedir. Provide both a raw ffs and Legacy U-Boot version of it. Replace HUMMINGBIRD_A31 with SUNXI kernel on armv7.img and include .dtb files for SUNXI and TEGRA kernels on the MSDOS partition. Let the controller provide a default name for pins. This makes pins easier to locate when we have multiple banks and a variable number of pins per bank. Attach gpio(4) to sunxigpio Test for kernel build directory before reading DTB list Add support for Allwinner A83T SoC. Add A83T files Fixup busdma sync and locking in the RX path. Disable batch RX/TX ints. Fix AHB2 register definition and explicitly set AHB2 parent to PLL_PERIPH0/2 -- this gives us 50% more bus bandwidth for emac Restore TX_INTERVAL_DEFAULT to 64 Drop the sunxi_emac_rx_batch feature. It was originally designed to reduce the amount of mutex unlock/lock cycles during the RX path on FreeBSD and if_input, but it is not required to drop the lock before calling if_percpuq_enqueue on NetBSD. Write back the data value instead of mask in sunxi_gpio_write Add a helper for exposing LED controls via sysctl. Add GPIO LED driver. add gpioleds Add misc. gates and resets driver, and explicitly enable PIO clocks at attach. Add fdtbus_get_string_index helper. Add driver for fixed-factor clocks. Add ffclock Remove the requirement for ehci to attach after companion devices. "go for it" - skrll@ Remove the hack to find companion devices and just assume 1 companion if ETTF flag is not set. Remove pass numbers for ehci/ohci now that the attach order no longer matters Use unsigned char for ctype functions, suggested by christos Add : to body of populate_sunxi to appease bash. port-evbarm/52388: Fix number of args to a debug printf.

FDT: Interrupts -- add support for interrupt maps The mct on exynos uses an interrupt map so we add support now. Devices represent their interrupts either through a combination of interrupt-parent and interrupts properties, where the 'interrupts' property is an array of one or more interrupt specifiers; or through a combination of an interrupt-parent that points to an interrupt-map, where the interrupt-map contains 2 or more entries consisting of an index, a pointer to an interrupt-controller, and a specifier for that controller. This code adds the ability to walk the interrupt-map and return a specifier. Unfortunately, the addition requires changing the interface to the interrupt-controllers' _establish and _intstr functions, so this check in contains a rototill of the three existing fdt interrupt controllers to use the new interface.
XU4 interrupt combiner / fake sysmmu Add sysmmu to have something that calls through to the combiner's establish routine. Debug the combiner with it. At this point the combiner is mostly done, but the interrupt handler has not been tested. This may never happen as we may never support any of the devices that use the combiner for interrupts. (Or maybe mct)
XU4 i2c, gpio & pinctrl changes modify exynos_gpio.c to support the new pinctrl model. set up the new pinctrl model in exynos_pinctrl.c Flesh out exynos_i2c.c and set it up to use the new pinctrl model. NOTE: exynos_i2c.c is still incomplete. I need to figure out what to set the prescaler and scaler to.

XU4 interrupt combiner Written but untested. I'm still confused about how to handle two things: 1) at interrupt disestablishment, where do I get an interrupt number so that I can disable the interrupt on the combiner? 2) How is interrupt multiplexing handled? I don't seem to have any sort of interrupt dispatch routine that takes the 1 interrupt that reaches the gic and turn it into one of eight combined interrupts to call the established interrupt for the original uncombined interrupt source.
XU4 FDT final checkpoint step N of N: get rid of baggage by removing whole files. What's left is in approximately the same shape as when the FDT update started, that is mostly broken. What's missing is most of the 76 devices recognized in the dtd. In other words, This is barely the start of a port. Next up, gpio then i2c, followed either by straightening out usb or getting the sdhc driver to work -- both probably require getting the interrupt combiner to work first. A large chunk of work is left to do on the clocks. I barely got them attaching to fdt and didn't do anything to take advantage of the information in the dtd. None of the other existing drivers, such as they are, properly request gpios, i2c or clocks, and, of course power domains are off the table.
XU4 FDT checkpoint It is rather amazing that XU4 gets as far as it does, given how much of this code simply doesn't work. Focusing now on getting everything converted to FDT. Next up USB and clocks. After that nuke everything that's not needed and start the port in earnest.
