2020-07-29arm: qemu: override flash accessors to use virtualizable instructionsArd Biesheuvel
Some instructions in the ARM ISA have multiple output registers, such as ldrd/ldp (load pair), where two registers are loaded from memory, but also ldr with indexing, where the memory base register is incremented as well when the value is loaded to the destination register. MMIO emulation under KVM is based on using the architecturally defined syndrome information that is provided when an exception is taken to the hypervisor. This syndrome information describes whether the instruction that triggered the exception is a load or a store, what the faulting address was, and which register was the destination register. This syndrome information can only describe one destination register, and when the trapping instruction is one with multiple outputs, KVM throws an error like kvm [615929]: Data abort outside memslots with no valid syndrome info on the host and kills the QEMU process with the following error: U-Boot 2020.07-rc3-00208-g88bd5b179360-dirty (Jun 06 2020 - 11:59:22 +0200) DRAM: 1 GiB Flash: error: kvm run failed Function not implemented R00=00000001 R01=00000040 R02=7ee0ce20 R03=00000000 R04=7ffd9eec R05=00000004 R06=7ffda3f8 R07=00000055 R08=7ffd9eec R09=7ef0ded0 R10=7ee0ce20 R11=00000000 R12=00000004 R13=7ee0cdf8 R14=00000000 R15=7ff72d08 PSR=200001d3 --C- A svc32 QEMU: Terminated This means that, in order to run U-Boot in QEMU under KVM, we need to avoid such instructions when accessing emulated devices. For the flash in particular, which is a hybrid between a ROM (backed by a read-only KVM memslot) when in array mode, and an emulated MMIO device (when in write mode), we need to take care to only use instructions that KVM can deal with when they trap. So override the flash read accessors that are used when running on QEMU under KVM. Note that the the 64-bit wide read and write accessors have been omitted: they are never used when running under QEMU given that it does not emulate CFI flash that supports it.

2020-07-29arm: qemu: disable the EFI workaround for older GRUBArd Biesheuvel
The QEMU/mach-virt targeted port of u-boot currently only runs on QEMU under TCG emulation, which does not model the caches at all, and so no users can exist that are relying on the GRUB hack for EFI boot. We will shortly enable support for running under KVM, but the GRUB hack (which disables all caches without doing cache cleaning by VA during ExitBootServices()) is likely to cause more problems than it solves, given that KVM hosts require correct maintenance if they incorporate non-architected system caches. So let's disable the GRUB hack by default on the QEMU/mach-virt port. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2020-07-29arm: qemu: enable LPAE on 32-bitArd Biesheuvel
QEMU's mach-virt machine only supports selecting CPU models that implement the virtualization extensions, and are therefore guaranteed to support LPAE as well. Initially, QEMU would not allow emulating these CPUs running in HYP mode (or EL2, for AArch64), but today, it also contains a complete implementation of the virtualization extensions themselves. This means we could be running U-Boot in HYP mode, in which case the LPAE long descriptor page table format is the only format that is supported. If we are not running in HYP mode, we can use either. So let's enable CONFIG_ARMV7_LPAE for qemu_arm_defconfig so that we get the best support for running with the MMU and caches enabled at any privilege level.

2020-07-29arm: enable allocate-on-read for LPAE's DCACHE_WRITEBACK/_WRITETHROUGHArd Biesheuvel
The LPAE versions of DCACHE_WRITEBACK and DCACHE_WRITETHROUGH are currently defined as no-allocate for both reads and writes, which deviates from the non-LPAE definition, and mostly defeats the purpose of enabling the caches in the first place. So align LPAE with !LPAE, and enable allocate-on-read for both. And while at it, add some clarification about the meaning of the chosen values.

2020-07-29arm: Add support for Qualcomm IPQ40xx familyRobert Marko
This introduces initial support for the popular Qualcomm IPQ40x8 and IPQ40x9 WiSoC series. IPQ40xx series have 4x Cortex A7 ARM-v7A cores. Supported are: IPQ4018, IPQ4019, IPQ4028 and IPQ4029. IPQ40x8 and IPQ40x9 use the same cores, but differ in addressable RAM size (1GB for IPQ40x9 and 256MB for IPQ40x8) and supported peripherals (IPQ40x8 lacks RGMII, LCD controller and EMMC/SDHCI controllers). IQP4028/IPQ4029 models differ from IPQ4018/IPQ4019 only by their rated temperatures rates with IPQ402X models being rated for wider temperature ranges. Initially this supports: * Simple clock driver (Only for UART1 now, will be extended) * Pinctrl driver (Supports UARTX and GPIO now, will be extended) * GPIOs already supported by msm_gpio driver with updates * UARTs already supported by serial_msm driver with updates Further peripherals will come in later patches.

2020-07-28azure: Switch to use the MSYS2 official installer as the CI baseBin Meng
Recent CI failures were seen [1] when building MSYS2 Windows host tools. The error messages are something like: downloading mingw32.db... downloading mingw32.db.sig... error: mingw32: key "4A6129F4E4B84AE46ED7F635628F528CF3053E04" is unknown error: mingw32: signature from "David Macek <david.macek.0@gmail.com>" is unknown trust error: failed to update mingw32 (invalid or corrupted database (PGP signature)) Per the MSYS2 official news [2], this was caused by a packager switch and several solutions were suggested, e.g.: a new package of msys2-keyring and a new msys2 installer that includes them are released. However right now we have been using the MSYS2 github CI base repo [3] for the MSYS2 build in U-Boot, but per the project information on the github webpage, it says: "This repository is unused/deprecated and will be remove after 2021-01-01". Since it is unmaintained it's unlikely the new PGP keys will be included in the git repo, and the only choice is to switch to use the MSYS2 official installer as the CI base instead.
