Since Linux 3.19, these products +must use this method to boot the Linux kernel. + +Work In Progress statement: +Device Tree files and Device Tree bindings that apply to AT91 SoCs and boards are +considered as "Unstable". To be completely clear, any at91 binding can change at +any time. So, be sure to use a Device Tree Binary and a Kernel Image generated from +the same source tree. +Please refer to the Documentation/devicetree/bindings/ABI.txt file for a +definition of a "Stable" binding/ABI. +This statement will be removed by AT91 MAINTAINERS when appropriate. + +Naming conventions and best practice: +- SoCs Device Tree Source Include files are named after the official name of + the product (at91sam9g20.dtsi or sama5d33.dtsi for instance). +- Device Tree Source Include files (.dtsi) are used to collect common nodes that can be + shared across SoCs or boards (sama5d3.dtsi or at91sam9x5cm.dtsi for instance). + When collecting nodes for a particular peripheral or topic, the identifier have to + be placed at the end of the file name, separated with a "_" (at91sam9x5_can.dtsi + or sama5d3_gmac.dtsi for example). +- board Device Tree Source files (.dts) are prefixed by the string "at91-" so + that they can be identified easily. Note that some files are historical exceptions + to this rule (sama5d3[13456]ek.dts, usb_a9g20.dts or animeo_ip.dts for example). diff --git a/MAINTAINERS b/MAINTAINERS index b65b22b0ea3e..2381bc195f94 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -877,6 +877,7 @@ F: arch/arm/boot/dts/at91*.dts F: arch/arm/boot/dts/at91*.dtsi F: arch/arm/boot/dts/sama*.dts F: arch/arm/boot/dts/sama*.dtsi +F: arch/arm/include/debug/at91.S ARM/ATMEL AT91 Clock Support M: Boris Brezillon <boris.brezillon@free-electrons.com> diff --git a/arch/arm/Kconfig.debug b/arch/arm/Kconfig.debug index 5ddd4906f7a7..e34d24949c6a 100644 --- a/arch/arm/Kconfig.debug +++ b/arch/arm/Kconfig.debug @@ -115,15 +115,18 @@ choice 0x80024000 | 0xf0024000 | UART9 config AT91_DEBUG_LL_DBGU0 - bool "Kernel low-level debugging on rm9200, 9260/9g20, 9261/9g10 and 9rl" + bool "Kernel low-level debugging on rm9200, 9260/9g20, 9261/9g10, 9rl, 9x5, 9n12" + select DEBUG_AT91_UART depends on HAVE_AT91_DBGU0 config AT91_DEBUG_LL_DBGU1 - bool "Kernel low-level debugging on 9263 and 9g45" + bool "Kernel low-level debugging on 9263, 9g45 and sama5d3" + select DEBUG_AT91_UART depends on HAVE_AT91_DBGU1 config AT91_DEBUG_LL_DBGU2 bool "Kernel low-level debugging on sama5d4" + select DEBUG_AT91_UART depends on HAVE_AT91_DBGU2 config DEBUG_BCM2835 @@ -1165,6 +1168,8 @@ config DEBUG_LL_INCLUDE string default "debug/sa1100.S" if DEBUG_SA1100 default "debug/8250.S" if DEBUG_LL_UART_8250 || DEBUG_UART_8250 + default "debug/at91.S" if AT91_DEBUG_LL_DBGU0 || AT91_DEBUG_LL_DBGU1 || \ + AT91_DEBUG_LL_DBGU2 default "debug/asm9260.S" if DEBUG_ASM9260_UART default "debug/clps711x.S" if DEBUG_CLPS711X_UART1 || DEBUG_CLPS711X_UART2 default "debug/meson.S" if DEBUG_MESON_UARTAO diff --git a/arch/arm/mach-at91/include/mach/debug-macro.S b/arch/arm/include/debug/at91.S index 2103a90f2261..80a6501b4d50 100644 --- a/arch/arm/mach-at91/include/mach/debug-macro.S +++ b/arch/arm/include/debug/at91.S @@ -1,6 +1,4 @@ /* - * arch/arm/mach-at91/include/mach/debug-macro.S - * * Copyright (C) 2003-2005 SAN People * * Debugging macro include header @@ -11,18 +9,23 @@ * */ -#include <mach/hardware.h> -#include <mach/at91_dbgu.h> - #if defined(CONFIG_AT91_DEBUG_LL_DBGU0) -#define AT91_DBGU AT91_BASE_DBGU0 +#define AT91_DBGU 0xfffff200 /* AT91_BASE_DBGU0 */ #elif defined(CONFIG_AT91_DEBUG_LL_DBGU1) -#define AT91_DBGU AT91_BASE_DBGU1 +#define AT91_DBGU 0xffffee00 /* AT91_BASE_DBGU1 */ #else /* On sama5d4, use USART3 as low level serial console */ -#define AT91_DBGU SAMA5D4_BASE_USART3 +#define AT91_DBGU 0xfc00c000 /* SAMA5D4_BASE_USART3 */ #endif +/* Keep in sync with mach-at91/include/mach/hardware.h */ +#define AT91_IO_P2V(x) ((x) - 0x01000000) + +#define AT91_DBGU_SR (0x14) /* Status Register */ +#define AT91_DBGU_THR (0x1c) /* Transmitter Holding Register */ +#define AT91_DBGU_TXRDY (1 << 1) /* Transmitter Ready */ +#define AT91_DBGU_TXEMPTY (1 << 9) /* Transmitter Empty */ + .macro addruart, rp, rv, tmp ldr \rp, =AT91_DBGU @ System peripherals (phys address) ldr \rv, =AT91_IO_P2V(AT91_DBGU) @ System peripherals (virt address) diff --git a/arch/arm/mach-at91/Kconfig b/arch/arm/mach-at91/Kconfig index 2395c68b3e32..cec0fb5d621a 100644 --- a/arch/arm/mach-at91/Kconfig +++ b/arch/arm/mach-at91/Kconfig @@ -174,14 +174,6 @@ config SOC_AT91SAM9N12 # ---------------------------------------------------------- endif # SOC_SAM_V4_V5 -config MACH_AT91RM9200_DT - def_bool SOC_AT91RM9200 - -config MACH_AT91SAM9_DT - def_bool SOC_AT91SAM9 - -# ---------------------------------------------------------- - comment "AT91 Feature Selections" config AT91_SLOW_CLOCK diff --git a/arch/arm/mach-at91/Makefile b/arch/arm/mach-at91/Makefile index 7b6424d40764..8ef7d9a2e855 100644 --- a/arch/arm/mach-at91/Makefile +++ b/arch/arm/mach-at91/Makefile @@ -2,7 +2,7 @@ # Makefile for the linux kernel. # -obj-y := setup.o sysirq_mask.o +obj-y := setup.o obj-$(CONFIG_SOC_AT91SAM9) += sam9_smc.o @@ -19,8 +19,8 @@ obj-$(CONFIG_SOC_SAMA5D3) += sama5d3.o obj-$(CONFIG_SOC_SAMA5D4) += sama5d4.o # AT91SAM board with device-tree -obj-$(CONFIG_MACH_AT91RM9200_DT) += board-dt-rm9200.o -obj-$(CONFIG_MACH_AT91SAM9_DT) += board-dt-sam9.o +obj-$(CONFIG_SOC_AT91RM9200) += board-dt-rm9200.o +obj-$(CONFIG_SOC_AT91SAM9) += board-dt-sam9.o # SAMA5 board with device-tree obj-$(CONFIG_SOC_SAMA5) += board-dt-sama5.o diff --git a/arch/arm/mach-at91/at91sam9260.c b/arch/arm/mach-at91/at91sam9260.c index 78137c24d90b..34e2abe82ae4 100644 --- a/arch/arm/mach-at91/at91sam9260.c +++ b/arch/arm/mach-at91/at91sam9260.c @@ -51,8 +51,6 @@ static void __init at91sam9260_map_io(void) static void __init at91sam9260_initialize(void) { arm_pm_idle = at91sam9_idle;
