2019-08-23arm64: dts: allwinner: orange-pi-3: Enable WiFiOndrej Jirman1-0/+46
Orange Pi 3 has AP6256 WiFi/BT module. WiFi part of the module is called bcm43356 and can be used with the brcmfmac driver. The module is powered by the two always on regulators (not AXP805). WiFi uses a PG port with 1.8V voltage level signals. SoC needs to be configured so that it sets up an 1.8V input bias on this port. This is done by the pio driver by reading the vcc-pg-supply voltage. You'll need a fw_bcm43456c5_ag.bin firmware file and nvram.txt configuration that can be found in the Xulongs's repository for H6: https://github.com/orangepi-xunlong/OrangePiH6_external/tree/master/ap6256 Mainline brcmfmac driver expects the firmware and nvram at the following paths relative to the firmware directory: brcm/brcmfmac43456-sdio.bin brcm/brcmfmac43456-sdio.txt Signed-off-by: Ondrej Jirman <megous@megous.com> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

2019-08-23arm64: dts: allwinner: a64: Add A64 OlinuXino board (with eMMC)Sunil Mohan Adapa2-0/+24
A64 OLinuXino board from Olimex has three variants with onboard eMMC: A64-OLinuXino-1Ge16GW, A64-OLinuXino-1Ge4GW and A64-OLinuXino-2Ge8G-IND. In addition, there are two variants without eMMC. One without eMMC and one with SPI flash. This suggests the need for separate device tree for the three eMMC variants. This patch has been tested on A64-OLinuXino-1Ge16GW with Linux 5.0 from Debain.

2019-08-22arm64: dts: fsl: Remove num-lanes property from PCIe nodesHou Zhiqiang5-17/+0
Remove the num-lanes property to avoid the driver setting the link width. On FSL Layerscape SoCs, the number of lanes assigned to PCIe controller is not fixed, it is determined by the selected SerDes protocol in the RCW (Reset Configuration Word). The PCIe link training is completed automatically through the selected SerDes protocol - the link width set-up is updated by hardware after power on reset, so the num-lanes property is not needed for Layerscape PCIe. The current num-lanes property was added erroneously, which actually indicates the maximum lanes the PCIe controller can support up to, instead of the lanes assigned to the PCIe controller. The link width set by SerDes protocol will be overridden by the num-lanes property, hence the subsequent re-training will fail when the assigned lanes do not match the value in the num-lanes property.

2019-08-19kexec_file: split KEXEC_VERIFY_SIG into KEXEC_SIG and KEXEC_SIG_FORCEJiri Bohac1-3/+3
This is a preparatory patch for kexec_file_load() lockdown. A locked down kernel needs to prevent unsigned kernel images from being loaded with kexec_file_load(). Currently, the only way to force the signature verification is compiling with KEXEC_VERIFY_SIG. This prevents loading usigned images even when the kernel is not locked down at runtime. This patch splits KEXEC_VERIFY_SIG into KEXEC_SIG and KEXEC_SIG_FORCE. Analogous to the MODULE_SIG and MODULE_SIG_FORCE for modules, KEXEC_SIG turns on the signature verification but allows unsigned images to be loaded. KEXEC_SIG_FORCE disallows images without a valid signature.
