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/[email protected]/) * Latest linux kernel is recommended to properly support flashes with more than one plane per lun (see: https://lore.kernel.org/lkml/[email protected]/) * 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 Christian Marangi (1): reset: airoha: convert to regmap API Mikhail Kshevetskiy (18): airoha/an7581: add CONFIG_TARGET_AN7581=y to the defconfig arm/airoha: add support for airoha en7523 SoC family arm: airoha: introduce AN7581 helpers to get SCU and CHIP_SCU regmaps arm: airoha: introduce EN7523 helpers to get SCU and CHIP_SCU regmaps clk: airoha: use CHIP_SCU regmap helper clk: airoha: add support for airoha en7523 SoC family configs: airoha: en7523: enable clk support reset: airoha: unify code using SCU regmap helper dt-bindings: reset: Add reset support for Airoha EN7523 reset: airoha: add support for airoha en7523 SoC family dts: airoha: en7523: add reset controller support configs: airoha: en7523: enable reset controller support net: airoha: unify code using SCU regmap helper net: airoha: add support for airoha en7523 SoC family dts: airoha: en7523: add ethernet controller support configs: airoha: en7523: enable ethernet controller support dts: airoha: en7523: add spinand flash support configs: airoha: en7523: enable spinand flashes support arch/arm/dts/en7523-evb-u-boot.dtsi | 11 ++ arch/arm/dts/en7523-u-boot.dtsi | 70 ++++++++++ arch/arm/include/asm/arch-airoha/scu-regmap.h | 13 ++ arch/arm/include/asm/arch-an7581 | 1 + arch/arm/include/asm/arch-en7523 | 1 + arch/arm/mach-airoha/Kconfig | 14 ++ arch/arm/mach-airoha/Makefile | 1 + arch/arm/mach-airoha/an7581/Makefile | 1 + arch/arm/mach-airoha/an7581/scu-regmap.c | 30 +++++ arch/arm/mach-airoha/en7523/Makefile | 4 + arch/arm/mach-airoha/en7523/init.c | 33 +++++ arch/arm/mach-airoha/en7523/scu-regmap.c | 38 ++++++ board/airoha/en7523/Makefile | 3 + board/airoha/en7523/en7523_rfb.c | 16 +++ configs/an7581_evb_defconfig | 1 + configs/en7523_evb_defconfig | 67 +++++++++ drivers/clk/airoha/clk-airoha.c | 127 ++++++++++++++++-- drivers/net/airoha_eth.c | 78 +++++++---- drivers/reset/reset-airoha.c | 106 ++++++++++++--- include/configs/en7523.h | 21 +++ .../dt-bindings/reset/airoha,en7523-reset.h | 61 +++++++++ 21 files changed, 642 insertions(+), 55 deletions(-) create mode 100644 arch/arm/dts/en7523-evb-u-boot.dtsi create mode 100644 arch/arm/dts/en7523-u-boot.dtsi create mode 100644 arch/arm/include/asm/arch-airoha/scu-regmap.h create mode 120000 arch/arm/include/asm/arch-an7581 create mode 120000 arch/arm/include/asm/arch-en7523 create mode 100644 arch/arm/mach-airoha/an7581/scu-regmap.c create mode 100644 arch/arm/mach-airoha/en7523/Makefile create mode 100644 arch/arm/mach-airoha/en7523/init.c create mode 100644 arch/arm/mach-airoha/en7523/scu-regmap.c create mode 100644 board/airoha/en7523/Makefile create mode 100644 board/airoha/en7523/en7523_rfb.c create mode 100644 configs/en7523_evb_defconfig create mode 100644 include/configs/en7523.h create mode 100644 include/dt-bindings/reset/airoha,en7523-reset.h -- 2.51.0
