net: axi_emac: Fix compilation warnings

2025-11-19T08:28:50Z

Fix compiler warnings about casting integers to pointers of different sizes by using uintptr_t as intermediate type. This ensures proper type conversion across 32-bit and 64-bit architectures.

Merge patch series "arm: airoha: add support for en7523 based boards"

2025-11-07T22:45:09Z

Mikhail Kshevetskiy says: This patch series adds basic support for the boards based on Airoha EN7523/EN7529/EN7562 SoCs. Due to ATF restrictions these boards are able to run 32-bit OS only. This patch series adds support for the following hardware: * console UART * ethernet controller/switch * spinand flash (in non-dma mode) The following issues may be expected: * Extra slow UBI attaching in U-Boot (up to 20 sec with fastmap enabled). This is caused by the lack of DMA support in the U-Boot airoha-snfi driver. * Linux airoha-snfi driver in some cases might damage you flash data (see: https://lore.kernel.org/lkml/20251012121707.2296160-15-mikhail.kshevetskiy@iopsys.eu/) * Latest linux kernel is recommended to properly support flashes with more than one plane per lun (see: https://lore.kernel.org/lkml/20251012121707.2296160-7-mikhail.kshevetskiy@iopsys.eu/) * It's NOT recommended to use flashes working in continuous mode because U-Boot airoha-snfi driver does not support such flashes properly. The patches was tested on the board: - SoC: Airoha EN7562 - RAM: 512 MB - SPI NAND: 4 Gbit, made by Toshiba - Linux boot: was NOT tested The U-Boot was chain-loaded from the running U-Boot. Airoha ATF-2.3 does not allow easily chain-loading of U-Boot from U-Boot, so a special FIT image (mimic linux kernel) was created 1) Create u-boot.its file with the following contents: === cut here === /dts-v1/; / { description = "ARM OpenWrt FIT (Flattened Image Tree)"; #address-cells = <1>; images { u-boot-ram { description = "OpenWrt U-Boot RAM image"; data = /incbin/("u-boot.bin.lzma"); type = "kernel"; arch = "arm"; os = "linux"; compression = "lzma"; load = <0x81e00000>; entry = <0x81e00000>; hash@1 { algo = "crc32"; }; hash@2 { algo = "sha1"; }; }; fdt-1 { description = "OpenWrt device tree blob"; data = /incbin/("dts/upstream/src/arm/airoha/en7523-evb.dtb"); type = "flat_dt"; arch = "arm"; compression = "none"; hash@1 { algo = "crc32"; }; hash@2 { algo = "sha1"; }; }; }; configurations { default = "config-ram-uboot"; config-ram-uboot { description = "OpenWrt RAM U-Boot"; kernel = "u-boot-ram"; fdt = "fdt-1"; }; }; }; ================== 2) Create u-boot.itb image to chain-load new u-boot from the old one lzma_alone e u-boot.bin u-boot.bin.lzma mkimage -f u-boot.its u-boot.itb 3) Load new u-boot from the old one U-Boot> tftpboot u-boot.itb && bootm Link: https://lore.kernel.org/r/20251101004503.2379529-1-mikhail.kshevetskiy@iopsys.eu

net: rswitch: Add Renesas R-Car X5H Ethernet Switch3 support

2025-11-06T19:08:37Z

Add support for the Renesas Ethernet Switch3 (RSW3) controller, present in R-Car Gen5 SoCs such as R-Car X5H (R8A78000). The hardware offset differences are handled via driver match data. The driver newly detects whether the switch prot is connected to xPCS or not, and if so, turns on MIOC bit 3. This is new on R-Car X5H. GWCKSC register is also programmed only on X5H. The rest of the operation is identical to RSwitch2. Signed-off-by: Marek Vasut Signed-off-by: Tam Nguyen Signed-off-by: Phong Hoang Signed-off-by: Thanh Quan Signed-off-by: Hai Pham
