To: barebox@lists.infradead.org Cc: Patrice Vilchez , Nicolas Ferre AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed. We created a new board for this device but based the chip support directly on 9260 files with little updates. Here is the chip page on Atmel wabsite: http://atmel.com/dyn/products/product_card.asp?part_id=4337 Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD Cc: Nicolas Ferre Cc: Patrice Vilchez --- arch/arm/Makefile | 1 + arch/arm/boards/at91sam9260ek/init.c | 21 +++++++++++++++- arch/arm/configs/at91sam9g20ek_defconfig | 39 ++++++++++++++++++++++++++++++ arch/arm/mach-at91/Kconfig | 33 +++++++++++++++++++++++++ arch/arm/mach-at91/Makefile | 1 + arch/arm/mach-at91/lowlevel_init.S | 3 +- 6 files changed, 96 insertions(+), 2 deletions(-) create mode 100644 arch/arm/configs/at91sam9g20ek_defconfig diff --git a/arch/arm/Makefile b/arch/arm/Makefile index e404ad0..77b6cf4 100644 --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -52,6 +52,7 @@ board-$(CONFIG_MACH_A9M2410) := a9m2410 board-$(CONFIG_MACH_A9M2440) := a9m2440 board-$(CONFIG_MACH_AT91SAM9260EK) := at91sam9260ek board-$(CONFIG_MACH_AT91SAM9263EK) := at91sam9263ek +board-$(CONFIG_MACH_AT91SAM9G20EK) := at91sam9260ek board-$(CONFIG_MACH_EDB9301) := edb93xx board-$(CONFIG_MACH_EDB9302) := edb93xx board-$(CONFIG_MACH_EDB9302A) := edb93xx diff --git a/arch/arm/boards/at91sam9260ek/init.c b/arch/arm/boards/at91sam9260ek/init.c index 7bb3c45..966dd2f 100644 --- a/arch/arm/boards/at91sam9260ek/init.c +++ b/arch/arm/boards/at91sam9260ek/init.c @@ -40,6 +40,25 @@ #include #include +/* + * board revision encoding + * bit 0: + * 0 => 1 mmc + * 1 => 2 mmcs (board from revision C) + */ +#define HAVE_2MMC (1 << 0) +static void ek_set_board_type(void) +{ + if (machine_is_at91sam9g20ek()) { + armlinux_set_architecture(MACH_TYPE_AT91SAM9G20EK); +#ifdef CONFIG_AT91_HAVE_2MMC + armlinux_set_revision(HAVE_2MMC); +#endif + } else { + armlinux_set_architecture(MACH_TYPE_AT91SAM9260EK); + } +} + static struct atmel_nand_data nand_pdata = { .ale = 21, .cle = 22, @@ -130,7 +149,7 @@ static int at91sam9260ek_devices_init(void) at91_add_device_sdram(64 * 1024 * 1024); armlinux_set_bootparams((void *)(AT91_CHIPSELECT_1 + 0x100)); - armlinux_set_architecture(MACH_TYPE_AT91SAM9260EK); + ek_set_board_type(); devfs_add_partition("nand0", 0x00000, 0x80000, PARTITION_FIXED, "self_raw"); dev_add_bb_dev("self_raw", "self0"); diff --git a/arch/arm/configs/at91sam9g20ek_defconfig b/arch/arm/configs/at91sam9g20ek_defconfig new file mode 100644 index 0000000..bc7c242 --- /dev/null +++ b/arch/arm/configs/at91sam9g20ek_defconfig @@ -0,0 +1,39 @@ +CONFIG_ARCH_AT91SAM9G20=y +CONFIG_MACH_AT91SAM9G20EK=y +CONFIG_AT91_HAVE_2MMC=y +CONFIG_ARM_OPTIMZED_STRING_FUNCTIONS=y +CONFIG_PROMPT="9G20-EK:" +CONFIG_LONGHELP=y +CONFIG_GLOB=y +CONFIG_PROMPT_HUSH_PS2="y" +CONFIG_CMDLINE_EDITING=y +CONFIG_AUTO_COMPLETE=y +CONFIG_PARTITION=y +CONFIG_DEFAULT_ENVIRONMENT_PATH="arch/arm/boards/at91sam9260ek/env" +CONFIG_CMD_EDIT=y +CONFIG_CMD_SLEEP=y +CONFIG_CMD_SAVEENV=y +CONFIG_CMD_LOADENV=y +CONFIG_CMD_EXPORT=y +CONFIG_CMD_PRINTENV=y +CONFIG_CMD_READLINE=y +CONFIG_CMD_MEMINFO=y +CONFIG_CMD_CRC=y +CONFIG_CMD_MTEST=y +CONFIG_CMD_MTEST_ALTERNATIVE=y +CONFIG_CMD_FLASH=y +CONFIG_CMD_BOOTM_SHOW_TYPE=y +CONFIG_CMD_RESET=y +CONFIG_CMD_GO=y +CONFIG_CMD_TIMEOUT=y +CONFIG_CMD_PARTITION=y +CONFIG_CMD_GPIO=y +CONFIG_NET=y +CONFIG_NET_DHCP=y +CONFIG_NET_PING=y +CONFIG_NET_TFTP=y +CONFIG_DRIVER_NET_MACB=y +# CONFIG_SPI is not set +CONFIG_I2C=y +CONFIG_DRIVER_CFI=y +CONFIG_CFI_BUFFER_WRITE=y diff --git a/arch/arm/mach-at91/Kconfig b/arch/arm/mach-at91/Kconfig index 288ee6f..1491161 100644 --- a/arch/arm/mach-at91/Kconfig +++ b/arch/arm/mach-at91/Kconfig @@ -7,6 +7,7 @@ config ARCH_TEXT_BASE config BOARDINFO default "Atmel 91SAM9260-EK" if MACH_AT91SAM9260EK default "Atmel at91sam9263-ek" if MACH_AT91SAM9263EK + default "Atmel at91sam9g20-ek" if MACH_AT91SAM9G20EK default "Bucyrus MMC-CPU" if MACH_MMCCPU default "Ronetix PM9263" if MACH_PM9263 @@ -28,6 +29,11 @@ config ARCH_AT91SAM9263 select CPU_ARM926T select HAS_MACB +config ARCH_AT91SAM9G20 + bool "AT91SAM9G20" + select CPU_ARM926T + select HAS_MACB + endchoice # ---------------------------------------------------------- @@ -50,6 +56,25 @@ endif # ---------------------------------------------------------- +if ARCH_AT91SAM9G20 + +choice + + prompt "AT91SAM9G20 Board Type" + +config MACH_AT91SAM9G20EK + bool "Atmel AT91SAM9G20-EK Evaluation Kit" + select HAVE_NAND_ATMEL_BUSWIDTH_16 + help + Select this if you are using Atmel's AT91SAM9G20-EK Evaluation Kit + that embeds only one SD/MMC slot. + +endchoice + +endif + +# ---------------------------------------------------------- + if ARCH_AT91SAM9263 choice @@ -88,4 +113,12 @@ config MTD_NAND_ATMEL_BUSWIDTH_16 On AT91SAM926x boards both types of NAND flash can be present (8 and 16 bit data bus width). +config AT91_HAVE_2MMC + bool "Have 2 MMC" + depends on MACH_AT91SAM9G20EK + help + Select this if you are using an Atmel AT91SAM9G20-EK Evaluation Kit + with 2 SD/MMC Slots.
