From fc04b923541d984b1544056fd3bfa8129d4e5aac Mon Sep 17 00:00:00 2001 From: Ryan Harkin Date: Fri, 9 Oct 2015 17:18:02 +0100 Subject: [PATCH] vexpress64: fvp dram: add DRAM configuration Create an additional FVP configuration to boot images pre-loaded into DRAM. Sometimes it's preferential to boot the model by loading the files directly into DRAM via model parameters, rather than using SemiHosting. An example of model parmaters that are used to pre-load the files into DRAM: --data cluster0.cpu0=Image@0x80080000 \ --data cluster0.cpu0=fvp-base-gicv2-psci.dtb@0x83000000 \ --data cluster0.cpu0=uInitrd@0x84000000 Signed-off-by: Ryan Harkin Reviewed-by: Linus Walleij [trini: Update board/armltd/vexpress64/Kconfig logic] Signed-off-by: Tom Rini --- arch/arm/Kconfig | 9 +++++++++ board/armltd/vexpress64/Kconfig | 2 +- board/armltd/vexpress64/MAINTAINERS | 5 +++++ configs/vexpress_aemv8a_dram_defconfig | 19 +++++++++++++++++++ include/configs/vexpress_aemv8a.h | 25 +++++++++++++++++++++++-- 5 files changed, 57 insertions(+), 3 deletions(-) create mode 100644 configs/vexpress_aemv8a_dram_defconfig diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 3a336e6fdf..798135574a 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -567,6 +567,15 @@ config TARGET_VEXPRESS64_BASE_FVP select ARM64 select SEMIHOSTING +config TARGET_VEXPRESS64_BASE_FVP_DRAM + bool "Support Versatile Express ARMv8a FVP BASE model booting from DRAM" + select ARM64 + help + This target is derived from TARGET_VEXPRESS64_BASE_FVP and over-rides + the default config to allow the user to load the images directly into + DRAM using model parameters rather than by using semi-hosting to load + the files from the host filesystem. + config TARGET_VEXPRESS64_JUNO bool "Support Versatile Express Juno Development Platform" select ARM64 diff --git a/board/armltd/vexpress64/Kconfig b/board/armltd/vexpress64/Kconfig index 9014418433..e05f353b80 100644 --- a/board/armltd/vexpress64/Kconfig +++ b/board/armltd/vexpress64/Kconfig @@ -1,4 +1,4 @@ -if TARGET_VEXPRESS64_BASE_FVP || TARGET_VEXPRESS64_JUNO +if TARGET_VEXPRESS64_BASE_FVP || TARGET_VEXPRESS64_JUNO || TARGET_VEXPRESS64_BASE_FVP_DRAM config SYS_BOARD default "vexpress64" diff --git a/board/armltd/vexpress64/MAINTAINERS b/board/armltd/vexpress64/MAINTAINERS index 0ba044d7ff..15b0a08646 100644 --- a/board/armltd/vexpress64/MAINTAINERS +++ b/board/armltd/vexpress64/MAINTAINERS @@ -10,6 +10,11 @@ M: Linus Walleij S: Maintained F: configs/vexpress_aemv8a_semi_defconfig +VEXPRESS_AEMV8A_DRAM BOARD +M: Ryan Harkin +S: Maintained +F: configs/vexpress_aemv8a_dram_defconfig + JUNO DEVELOPMENT PLATFORM BOARD M: Linus Walleij S: Maintained diff --git a/configs/vexpress_aemv8a_dram_defconfig b/configs/vexpress_aemv8a_dram_defconfig new file mode 100644 index 0000000000..e9fc8706f4 --- /dev/null +++ b/configs/vexpress_aemv8a_dram_defconfig @@ -0,0 +1,19 @@ +CONFIG_ARM=y +CONFIG_TARGET_VEXPRESS64_BASE_FVP_DRAM=y +CONFIG_SYS_MALLOC_F_LEN=0x2000 +CONFIG_DEFAULT_DEVICE_TREE="vexpress64" +# CONFIG_CMD_CONSOLE is not set +# CONFIG_CMD_IMLS is not set +# CONFIG_CMD_XIMG is not set +# CONFIG_CMD_EDITENV is not set +# CONFIG_CMD_ENV_EXISTS is not set +# CONFIG_CMD_LOADS is not set +# CONFIG_CMD_FLASH is not set +# CONFIG_CMD_FPGA is not set +# CONFIG_CMD_ITEST is not set +# CONFIG_CMD_SETEXPR is not set +# CONFIG_CMD_NFS is not set +# CONFIG_CMD_MISC is not set +CONFIG_DM=y +CONFIG_DM_SERIAL=y +CONFIG_SYS_PROMPT="VExpress64# " diff --git a/include/configs/vexpress_aemv8a.h b/include/configs/vexpress_aemv8a.h index c54baf8c7b..c1e2e111c9 100644 --- a/include/configs/vexpress_aemv8a.h +++ b/include/configs/vexpress_aemv8a.h @@ -30,7 +30,8 @@ #define CONFIG_BOOTP_VCI_STRING "U-boot.armv8.vexpress_aemv8a" /* Link Definitions */ -#ifdef CONFIG_TARGET_VEXPRESS64_BASE_FVP +#if defined(CONFIG_TARGET_VEXPRESS64_BASE_FVP) || \ + defined(CONFIG_TARGET_VEXPRESS64_BASE_FVP_DRAM) /* ATF loads u-boot here for BASE_FVP model */ #define CONFIG_SYS_TEXT_BASE 0x88000000 #define CONFIG_SYS_INIT_SP_ADDR (CONFIG_SYS_SDRAM_BASE + 0x03f00000) @@ -103,7 +104,8 @@ #define GICR_BASE (0x2f100000) #else -#ifdef CONFIG_TARGET_VEXPRESS64_BASE_FVP +#if defined(CONFIG_TARGET_VEXPRESS64_BASE_FVP) || \ + defined(CONFIG_TARGET_VEXPRESS64_BASE_FVP_DRAM) #define GICD_BASE (0x2f000000) #define GICC_BASE (0x2c000000) #elif CONFIG_TARGET_VEXPRESS64_JUNO @@ -233,6 +235,25 @@ #define CONFIG_BOOTDELAY 1 +#elif CONFIG_TARGET_VEXPRESS64_BASE_FVP_DRAM +#define CONFIG_EXTRA_ENV_SETTINGS \ + "kernel_addr=0x80080000\0" \ + "initrd_addr=0x84000000\0" \ + "fdt_addr=0x83000000\0" \ + "fdt_high=0xffffffffffffffff\0" \ + "initrd_high=0xffffffffffffffff\0" + +#define CONFIG_BOOTARGS "console=ttyAMA0 earlyprintk=pl011,"\ + "0x1c090000 debug user_debug=31 "\ + "androidboot.hardware=fvpbase "\ + "root=/dev/vda2 rw "\ + "rootwait "\ + "loglevel=9" + +#define CONFIG_BOOTCOMMAND "booti $kernel_addr $initrd_addr $fdt_addr" + +#define CONFIG_BOOTDELAY 1 + #else #error "Unknown board variant" #endif -- 2.39.5
