The Wifx L1 is a SAMA5D4 LoRaWAN gateway. It boots from NAND, but this can be overridden by inserting a bootable SD-Card. This first port only provides second-stage SD-Card support. It enables use of UART, I2C/EEPROM, Ethernet and SD-Card. For NAND use on SAMA5D4, an updated Linux driver was ported to barebox. This will follow separately. v1 -> v2: - skip stack setup on SAMA5D2 (Sascha) - Add Sam's Acked-by - Rebase on upstream/next Ahmad Fatoum (11): ARM: at91: sama5: switch to nonnaked entry functions ARM: at91: sama5d4: add entry point helpers ARM: at91: sama5d4: enable for DT use net: macb: match atmel,sama5d4-gem compatible i2c: at91: extend for SAMA5D4 support eeprom: at24: add 24mac402/602 support driver: always ensure probe of RAM registered with mem_platform_driver common: deep-probe: don't build without CONFIG_OFDEVICE pinctrl: at91: make deep-probe compatible ARM: at91: make bootsource code generic to all SAMA5 ARM: at91: SAMA5D4: add Wifx L1 support arch/arm/boards/Makefile | 1 + .../boards/microchip-ksz9477-evb/lowlevel.c | 6 +- .../arm/boards/sama5d27-giantboard/lowlevel.c | 4 +- arch/arm/boards/sama5d27-som1/lowlevel.c | 4 +- arch/arm/boards/sama5d3_xplained/lowlevel.c | 6 +- arch/arm/boards/sama5d4_wifx/Makefile | 4 + arch/arm/boards/sama5d4_wifx/board.c | 38 ++ arch/arm/boards/sama5d4_wifx/lowlevel.c | 18 + arch/arm/dts/Makefile | 1 + arch/arm/dts/at91-sama5d4_wifx_l1.dts | 358 ++++++++++++++++++ arch/arm/dts/sama5d4.dtsi | 9 + arch/arm/mach-at91/Kconfig | 11 + arch/arm/mach-at91/Makefile | 3 +- arch/arm/mach-at91/bootm-barebox.c | 3 +- arch/arm/mach-at91/ddramc.c | 7 + arch/arm/mach-at91/include/mach/barebox-arm.h | 23 +- arch/arm/mach-at91/include/mach/cpu.h | 1 - arch/arm/mach-at91/include/mach/ddramc.h | 1 + .../mach-at91/include/mach/sama5_bootsource.h | 5 + arch/arm/mach-at91/sama5_bootsource.c | 36 ++ arch/arm/mach-at91/sama5d2.c | 15 - arch/arm/mach-at91/setup.c | 3 - common/Makefile | 2 +- drivers/eeprom/at24.c | 2 + drivers/i2c/busses/i2c-at91.c | 14 +- drivers/net/macb.c | 1 + drivers/pinctrl/pinctrl-at91.c | 20 +- images/Makefile.at91 | 4 + include/deep-probe.h | 7 + include/driver.h | 13 +- 30 files changed, 572 insertions(+), 48 deletions(-) create mode 100644 arch/arm/boards/sama5d4_wifx/Makefile create mode 100644 arch/arm/boards/sama5d4_wifx/board.c create mode 100644 arch/arm/boards/sama5d4_wifx/lowlevel.c create mode 100644 arch/arm/dts/at91-sama5d4_wifx_l1.dts create mode 100644 arch/arm/dts/sama5d4.dtsi create mode 100644 arch/arm/mach-at91/sama5_bootsource.c -- 2.30.2
