* rockchip: add Orange Pi R1 Plus supportTianling Shen2023-06-097-3/+505
| | | | | | | | | | | | | | | | | Orange Pi R1 Plus is a Rockchip RK3328 based SBC by Xunlong. This device is similar to the NanoPi R2S, and has a 16MB SPI NOR (mx25l12805d). The reset button is changed to directly reset the power supply, another detail is that both network ports have independent MAC addresses. Note: booting from SPI is currently unsupported, you have to install the image on a SD card.

* kernel: enable (ARM|ARM64)_MODULE_PLTS in generic configTony Ambardar2023-05-241-1/+0
| | | | | | | | | | | | | | | | | | | | | This allows loading modules with large memory requirements, recently needed while testing on armvirt/32. Past forum discussions [1] and bug reports [2] also raised this and the ipq806x target already set it in response [3]. Given this increases kernel image size by only ~1KB, is generally useful on multi-platform kernels, and enabled by default on upstream arm32 Linux, add it to the generic config. The setting has similar utility on arm64, is a requirement for KASLR, and already enabled on most OpenWrt aarch64 targets, so pull this into the top-level generic config.

* kernel: improve handling of CONFIG_IO_URINGTony Ambardar2023-05-032-2/+0
| | | | | | | | | | | | | | | | | | | | | | Kernel setting CONFIG_IO_URING supports high-performance I/O for file access and servers, generally for more performant platforms, and adds ~45 KB to kernel sizes. The need for this on less "beefy" devices is questionable, as is the size cost considering many platforms have kernel size limits which require tricky repartitioning if outgrown. The size cost is also large relative to the ~180 KB bump expected between major OpenWRT kernel releases. No OpenWrt packages have hard dependencies on this; samba4 and mariadb can take advantage if available (+KERNEL_IO_URING:liburing) but otherwise build and work fine. Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting in Config-kernel.in (default Y), remove it from those target configs which unconditionally enable it, and update the defaults to enable it conditionally only on more powerful 64-bit x86 and arm devices. It may still be manually enabled as needed for high-performance custom builds. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
* kernel: Deactivate CONFIG_COMPATHauke Mehrtens2023-04-292-7/+0
| | | | | | | | | | | | | | This deactivates the CONFIG_COMPAT kernel option. With CONFIG_COMPAT the kernel will provide syscall interfaces for arm32 binaries in addition to the interfaces needed for arm64 binaries. In OpenWrt the complete userspace is compiled for this specific architecture and support for 32 bit ARM applications is not needed. This reduces the size and the attack surface for the systems. On all other targets CONFIG_COMPAT is already deactivated. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

* kernel: Activate CONFIG_ARM64_SW_TTBR0_PANHauke Mehrtens2023-04-292-2/+0
| | | | | | | | | | | | | This activates the CONFIG_ARM64_SW_TTBR0_PAN option for all arm64 kernels by default. The CONFIG_ARM64_SW_TTBR0_PAN option prevents the kernel form accessing user space memory directly. This makes it harder to exploit the kernel. This is activated by default and was already activate on all other arm64 targets before. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Activate CONFIG_HARDENED_USERCOPY for all targetsHauke Mehrtens2023-04-292-2/+0

This was not activated for ARCHS38 before because of a bug in the Linux kernel 5.4 till 5.14, which as fixed and is described here: https://github.com/foss-for-synopsys-dwc-arc-processors/linux/issues/15 I do not know why this was deactivated for mt7629 and rockchip.
