[PATCH v2 0/3] watchdog: K3: Add RTI watchdog support
by Jan Kiszka 17 Aug '20

17 Aug '20

This brings watchdog support for the TI K3 SoCs, derived from the Linux kernel, augmented with firmware loading as needed on the AM65x. Tested on the AM65x EVM and the IOT2050 (also AM65x-based, upstream support will be posted soon). Changes in v2: - keep watchdog powered when handing over to Linux - drop unneeded explicit power-on - account for RTI firmware locking the power domain Jan Jan Kiszka (3): watchdog: Add support for K3 RTI watchdog watchdog: rti_wdt: Add support for loading firmware arm: dts: k3: Add RTI watchdogs arch/arm/dts/k3-am65-mcu.dtsi | 9 ++ arch/arm/dts/k3-j721e-main.dtsi | 18 ++++ drivers/watchdog/Kconfig | 27 ++++++ drivers/watchdog/Makefile | 4 + drivers/watchdog/rti_wdt.c | 147 ++++++++++++++++++++++++++++++++ drivers/watchdog/rti_wdt_fw.S | 20 +++++ 6 files changed, 225 insertions(+) create mode 100644 drivers/watchdog/rti_wdt.c create mode 100644 drivers/watchdog/rti_wdt_fw.S -- 2.26.2

board/arch-specific artifacts vs. make clean
by Jan Kiszka 17 Aug '20

17 Aug '20

Hi, despite some futile attempts (arch/arm/mach-rmobile/Makefile, board/imgtec/boston/config.mk), CLEAN_FILES cannot be extended outside of the top-level Makefile as clean is in no-dot-config-targets, and the arch and board specific config.mk files are not evaluated then. How to clean extra files that a board or an arch defines? Add them all to the top-level Makefile?

[RESEND PATCH v2 00/18] Add new board: Xen guest for ARM64
by Anastasiia Lukianenko 16 Aug '20

16 Aug '20

From: Anastasiia Lukianenko <anastasiia_lukianenko(a)epam.com> This work introduces Xen [1] guest ARM64 board support in U-Boot with para-virtualized (PV) [2] block and serial drivers: xenguest_arm64. This board is to be run as a virtual Xen guest with U-boot as its primary bootloader. The rationale behind introducing this board is a better and simpler decoupling of the guest from the initial privileged domain which starts a guest’s virtual machine: there are cross dependencies between the guest OS and initial privileged domain (Domain-0) such as Domain-0 needs guest's kernel and may need its device tree to boot it. These dependencies interfere if the kernel or guest OS needs to be updated, thus having a unified bootloader in Domain-0 allows resolving this: 1. U-boot boot scripts, which are stored on the guest’s virtual disk, are guest specific, so any change in the guest’s configuration can be handled by the guest itself. 2. Guest OS’ kernel can be updated if OS’ needs that without any help from Domain-0. 3. Using the Device Tree Overlay mechanism it is possible to customize the device tree entries yet at bootloader stage inside the guest itself, so the base device tree provided by Xen can be customized. Xen support for U-boot was implemented by introducing a new Xen guest ARM64 board and porting essential drivers from MiniOS [3] as well as some of the work previously done by NXP [4]: 1. PV block device front driver with XenStore based device enumeration, new UCLASS_PVBLOCK; 2. PV serial console device front driver; 3. Xen hypervisor support with minimal set of the essential headers adapted from Linux kernel; 4. grant table support; 5. event channel support, without IRQ support, but polling; 6. xenbus support; 7. dynamic RAM size as defined in the device tree instead of statically defined values; 8. position-independent pre-relocation code is used as we cannot statically define any start addresses at compile time which is up to Xen to choose at run-time; 9. new defconfig introduced: xenguest_arm64_defconfig. Please note, that due to the fact that para-virtualized serial driver requires some of the Xen functionality available late not all the printouts are available at the very start including U-Boot banner, memory size etc. All the above was tested with block driver related commands (info/part/read/write), FAT and ext4 operations work properly, the Linux kernel can start. Thank you in advance, Anastasiia Lukianenko, Oleksandr Andrushchenko Changes since v1: ================= 1. Added test for new lib sscanf function 2. Fixed data cache maintenance process 3. Added more comments and explanations 4. Removed unnecessary code, which is not related to ARM64 architecture 5. Added board documentation 6. Coding style cleanup 7.
