2020-12-09efi: capsule: clean scatter-gather entries from the D-cacheArd Biesheuvel1-0/+5
Scatter-gather lists passed to UpdateCapsule() should be cleaned from the D-cache to ensure that they are visible to the CPU after a warm reboot before the MMU is enabled. On ARM and arm64 systems, this implies a D-cache clean by virtual address to the point of coherency. However, due to the fact that the firmware itself is not able to map physical addresses back to virtual addresses when running under the OS, this must be done by the caller.

2020-12-09Merge tag 'omap-for-v5.11/genpd-drivers-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/driversArnd Bergmann3-1/+19
Driver changes for omaps for genpd for v5.11 merge window This series of changes allows booting am335x with genpd and device tree data without the legacy platform data. Also at least am437x can be booted with gendp with power domain and dts data. The SoC specific dts changes will be a separate pull request. We need the following driver changes merged before the dts changes can be done: - platform code needs a few improvments to probe l4_wkup first for clocks, and to bail out when there is no platform data - ti-sysc driver needs a non-urgent fix for asserting rstctrl reset only after disabling the clocks, to probe modules with no known control registers, and added quirk handling for gpmc devices - omap-prm driver needs a non-urgent fix for reset status bit, support added for pm_clk, and then we add the rest of am335x power domain data - clock driver for am335x needs to keep l3_main clock enabled with genpd for suspend and resume to work - wkup_m3 remoteproc driver needs support added for reset control if available instead of the legacy pdata callbacks - pm33xx driver needs PM runtime support added for genpd The am335x specific driver changes for the clock, wkup_m3, pm33xx and remoteproc drivers are quite trivial and have not caused merge conflicts in Linux next. I did not get acks for these changes except from Santosh but had already pushed out the branch already at that point. So I've added the related driver maintainers to Cc. * tag 'omap-for-v5.11/genpd-drivers-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: remoteproc/wkup_m3: Use reset control driver if available soc: ti: pm33xx: Enable basic PM runtime support for genpd soc: ti: omap-prm: am3: add genpd support for remaining PRM instances soc: ti: omap-prm: Add pm_clk for genpd clk: ti: am33xx: Keep am3 l3 main clock always on for genpd bus: ti-sysc: Implement GPMC debug quirk to drop platform data bus: ti-sysc: Support modules without control registers ARM: OMAP2+: Probe PRCM first to probe l4_wkup with simple-pm-bus ARM: OMAP2+: Check for inited flag bus: ti-sysc: Assert reset only after disabling clocks soc: ti: omap-prm: Do not check rstst bit on deassert if already deasserted bus: ti-sysc: Fix bogus resetdone warning on enable for cpsw bus: ti-sysc: Fix reset status check for modules with quirks ARM: OMAP2+: Fix missing select PM_GENERIC_DOMAINS_OF ARM: OMAP2+: Fix location for select PM_GENERIC_DOMAINS Link: https://lore.kernel.org/r/pull-1606806458-694517@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

He also disables the USB3 PHY node for devices that lack USB3 and adds USB3 support to the Luxul XWR-3150 DTS. - Jonathan drops the incorrect 'io-channel-ranges' from the Cygnus SoC DTSI. - Maxime disables the Wi-Fi frequencies (around 2.4GHz) for HDMI on the Raspberry Pi 4 due to some cross-talk between the two blocks. - Pavel updates the DWC2 USB controller RX FIFO sizes to be more accurate for all BCM283x (Raspberr Pi) SoCs. - Florian updates all BCM5301x and NSP Device Tree files to allow switching the Broadcom B53 Ethernet switch device tree binding to YAML. * tag 'arm-soc/for-5.11/devicetree' of https://github.com/Broadcom/stblinux: (22 commits) dt-bindings: net: dsa: b53: Add YAML bindings ARM: dts: NSP: Provide defaults ports container node ARM: dts: NSP: Add a SRAB compatible string for each board ARM: dts: NSP: Fix Ethernet switch SGMII register name ARM: dts: NSP: Update ethernet switch node name ARM: dts: BCM5301X: Provide defaults ports container node ARM: dts: BCM5301X: Add a default compatible for switch node ARM: dts: BCM5301X: Update Ethernet switch node name dt-bindings: net: dsa: Document sfp and managed properties dt-bindings: net: dsa: Extend switch nodes pattern ARM: dts: bcm283x: increase dwc2's RX FIFO size ARM: dts: rpi-4: disable wifi frequencies ARM: dts: Cygnus: Drop incorrect io-channel-ranges property.

2020-12-08ARM: 9034/1: __div64_32(): straighten up inline asm constraintsNicolas Pitre1-15/+6
The ARM version of __div64_32() encapsulates a call to __do_div64 with non-standard argument passing. In particular, __n is a 64-bit input argument assigned to r0-r1 and __rem is an output argument sharing half of that r0-r1 register pair. With __n being an input argument, the compiler is in its right to presume that r0-r1 would still hold the value of __n past the inline assembly statement. Normally, the compiler would have assigned non overlapping registers to __n and __rem if the value for __n is needed again. However, here we enforce our own register assignment and gcc fails to notice the conflict. In practice this doesn't cause any problem as __n is considered dead after the asm statement and *n is overwritten. However this is not always guaranteed and clang rightfully complains. Let's fix it properly by making __n into an input-output variable. This makes it clear that those registers representing __n have been modified. Then we can extract __rem as the high part of __n with plain C code. This asm constraint "abuse" was likely relied upon back when gcc didn't handle 64-bit values optimally. Turns out that gcc is now able to optimize things and produces the same code with this patch applied.

2020-12-08ARM: 9030/1: entry: omit FP emulation for UND exceptions taken in kernel modeArd Biesheuvel3-30/+49
There are a couple of problems with the exception entry code that deals with FP exceptions (which are reported as UND exceptions) when building the kernel in Thumb2 mode: - the conditional branch to vfp_kmode_exception in vfp_support_entry() may be out of range for its target, depending on how the linker decides to arrange the sections; - when the UND exception is taken in kernel mode, the emulation handling logic is entered via the 'call_fpe' label, which means we end up using the wrong value/mask pairs to match and detect the NEON opcodes. Since UND exceptions in kernel mode are unlikely to occur on a hot path (as opposed to the user mode version which is invoked for VFP support code and lazy restore), we can use the existing undef hook machinery for any kernel mode instruction emulation that is needed, including calling the existing vfp_kmode_exception() routine for unexpected cases. So drop the call to call_fpe, and instead, install an undef hook that will get called for NEON and VFP instructions that trigger an UND exception in kernel mode. While at it, make sure that the PC correction is accurate for the execution mode where the exception was taken, by checking the PSR Thumb bit.

2020-12-08ARM: 9029/1: Make iwmmxt.S support Clang's integrated assemblerJian Cai2-44/+92
This patch replaces 6 IWMMXT instructions Clang's integrated assembler does not support in iwmmxt.S using macros, while making sure GNU assembler still emit the same instructions. This should be easier than providing full IWMMXT support in Clang. This is one of the last bits of kernel code that could be compiled but not assembled with clang. Once all of it works with IAS, we no longer need to special-case 32-bit Arm in Kbuild, or turn off CONFIG_IWMMXT when build-testing. "Intel Wireless MMX Technology - Developer Guide - August, 2002" should be referenced for the encoding schemes of these extensions.

2020-12-08ARM: 9028/1: disable KASAN in call stack capturing routinesArd Biesheuvel1-0/+3
KASAN uses the routines in stacktrace.c to capture the call stack each time memory gets allocated or freed. Some of these routines are also used to log CPU and memory context when exceptions are taken, and so in some cases, memory accesses may be made that are not strictly in line with the KASAN constraints, and may therefore trigger false KASAN positives. So follow the example set by other architectures, and simply disable KASAN instrumentation for these routines.

ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected by silicon errata #1742098 and #1655431, respectively, where the second instruction of a AES instruction pair may execute twice if an interrupt is taken right after the first instruction consumes an input register of which a single 32-bit lane has been updated the last time it was modified. This is not such a rare occurrence as it may seem: in counter mode, only the least significant 32-bit word is incremented in the absence of a carry, which makes our counter mode implementation susceptible to these errata. So let's shuffle the counter assignments around a bit so that the most recent updates when the AES instruction pair executes are 128-bit wide.

Due to strobe signal not being propagated from CPU to securam the securam needs to be mapped as device or strongly ordered memory to work properly. Otherwise, updating to one offset may affect the adjacent locations in securam.

2020-12-03ARM: dts: exynos: Reduce assigned-clocks entries for SPI0 on Artik5 boardMarek Szyprowski1-5/+2
Commit 2024b130b0c8 ("ARM: dts: exynos: Add Ethernet to Artik 5 board") added ethernet chip on SPI0 bus and the whole bunch of assigned clock entries to ensure proper clock rates and topology. Limit the assigned clock parents only to the direct clocks of the SPI0 device and assume that MPLL clock is already properly configured. The applied clock topology was incorrect as some clocks between were missing, what resulted in the following warning: clk: failed to reparent div_mpll_pre to mout_mpll: -22 Fixes: 2024b130b0c8 ("ARM: dts: exynos: Add Ethernet to Artik 5 board") Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Link: https://lore.kernel.org/r/20201202122029.22198-1-m.szyprowski@samsung.com Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
