* tools/coreutils: build chownFelix Fietkau2022-01-271-1/+1
| | | | | | | On ARM macOS, injecting extra shared libraries does not work for system binaries. This causes fakeroot to fail for chown calls Signed-off-by: Felix Fietkau <nbd@nbd.name>

* netfilter: correct some dependenciesTiago Gaspar2022-01-271-2/+2
| | | | | | | | | | | | nf-nathelper-extra and nf-conntrack-netlink had iptables related dependencies, yet, when looking for the respective kernel symbols and checking it's dependencies it was confirmed that iptables wasn't required and that these were either it's own moodule or tool independent (nftables or iptables). Correct these and make sure no unneeded extras are pulled in. Signed-off-by: Tiago Gaspar <tiagogaspar8@gmail.com>
* rockchip: disable UHS modes for NanoPi R4SDavid Bauer2022-01-271-0/+26
| | | | | | | | | | | The NanoPi R4S leaves the SD card in 1.8V signalling when rebooting while U-Boot requires the card to be in 3.3V mode. Remove UHS support from the SD controller so the card remains in 3.3V mode. This reduces transfer speeds but ensures a reboot whether from userspace or following a kernel panic is always working.

* mediatek: mt7623: include regular AHCI PCI driverDaniel Golle2022-01-251-1/+1
| | | | | | | | | The legacy image for the UniElec U7623-02 until now included kmod-ata-ahci-mtk. The MT7623 chip doesn't have that IP and that board uses a PCIe-connected AHCI controller for the SATA port and mSATA-pins of the mPCIe socket. Hence include kmod-ata-ahci instead.

* mediatek: mt7623: rework images for U7623-02 boardDaniel Golle2022-01-2313-313/+95
| | | | | | | | | | | | | | | | | | | | | | Users of older OpenWrt versions need sysupgrade using the *emmc.img.gz file once which will upgrade U-Boot and switch to the new image layout. Users of the vendor firmware need to first flash the legacy image to then sunsequently carry out a full-flash upgrade. Alternatively the board can also be flashed using MediaTek's proprietary SP Flash Tool. Configuration as well as persistent MAC address will be lost once at this point and you will have to redo (or restore) all configuration manually. To restore the previous persistent MAC address users may set it manually using fw_setenv ethaddr 00:11:22:33:44:55 For future upgrades once running OpenWrt past this commit, the usual *sysupgrade.itb file can be used.

* ramips: correct vendor name for COMFAST/JoowinRodrigo Araujo2022-01-227-44/+50
| | | | | | | | | | | | | | | | When Joowin WR758AC V1 and V2 devices were added, they should have been added with the primary manufacturer name which is COMFAST, since Joowin is just an alternate vendor name on some coutries or stores. Fix this by changing the the vendor name on the respective files and set Joowin as ALT0 variants while ensuring compatibility for early users. Also adjust the model names to better follow the naming rules. As a side effect, fix mt76x8 network script which was left incorrectly unsorted on the case block conditions.

* ramips: read Tenbay T-MB5EU address from single locationDavid Bauer2022-01-221-5/+2
| | | | | | | | | | | | | Currently the WAN MAC address is read from a different offset contrary to all other addresses. There's conflicting information whether offset 0x28 on the factory partition contains the valid WAN mac for all devices while 0x4 seems to be uniform.

The 5GHz MAC address OUI is +2 in the first EUI octet. We currently don't do this in OpenWrt. Ignore this offset for now. With the current assignment, recurring MAC addresses between radios is already taken care of. Signed-off-by: David Bauer <mail@david-bauer.net>

* ath79: add support for reset key on MikroTik RB912UAG-2HPnDDenis Kalashnikov2022-01-197-8/+282
| | | | | | | | | | | | | | | | | | | | | | On MikroTik RB91x board series a reset key shares SoC gpio line #15 with NAND ALE and NAND IO7. So we need a custom gpio driver to manage this non-trivial connection schema. Also rb91x-nand needs to have an ability to disable a polling of the key while it works with NAND. While we've been integrating rb91x-key into a firmware, we've figured out that: * In the gpio-latch driver we need to add a "cansleep" suffix to several gpiolib calls, * When gpio-latch and rb91x-nand fail to get a gpio and an error is -EPROBE_DEFER, they shouldn't report about this, since this actually is not an error and occurs when the gpio-latch probe function is called before the rb91x-key probe. We fix these related things here too.

| | | | | | | | | | | | | | | On ar71xx, it was possible to overwrite the name of the spi-nor mtd device identifier using the flash_platform_data which each mach-*.c could adjust for its devices. A similar feature was introduced for mtd-physmap in devicetree's. The property linux,mtd-name can be used to set the name and provide a stable identifier for mtdpart from the bootloader.

* lantiq: xrx200: enable use of baby jumbo framesThomas Nixon2022-01-166-12/+484
| | | | | | | | | | | | | | | | | | xrx200 max MTU is reduced so that it works correctly when set to the max, and the max MTU of the switch is increased to match. In 5.10, the switch driver now enables non-standard MTUs on a per-port basis, with the overall frame size set based on the cpu port. When the MTU is not used, this should have no effect. The maximum packet size is limited as large packets cause the switch to lock up. 0702-net-lantiq-add-support-for-jumbo-frames.patch comes from net-next commit 998ac358019e491217e752bc6dcbb3afb2a6fa3e. In 5.4, all switch ports are configured to accept the max MTU, as 5.4 does not have port_max_mtu/port_change_mtu callbacks. Signed-off-by: Thomas Nixon <tom@tomn.co.uk>
