The boot process is similar to boot image with linux: - android bootloader (ABL) unpacks android boot image - ABL sets `linux,initrd-start property` in chosen node in unpacked FDT - ABL sets x0 register to FDT address, and passes control to u-boot - u-boot reads x0 register, and stores it in `prevbl_fdt_addr` env variable - u-boot reads `linux,initrd-start` property, and stores it in `prevbl_initrd_start_addr` In this way, u-boot bootcmd relies on `prevbl_initrd_start_addr` env variable, and boils down to `bootm $prevbl_initrd_start_addr`. If more control on boot process is desired, pack a boot script in FIT image, and put it to default configuration What done: - strip unneeded config options - add FIT image support - add framebuffer node, u-boot logo and video console - increase LMB_MAX_REGIONS, to store all linux dtb reserved memory regions - add linux kernel image header Uart driver causes hang, when u-boot is used in android boot image instead of linux. Temporary disable console driver, until investigated and fixed. Signed-off-by: Dzmitry Sankouski Cc: Ramon Fried --- Changes for v2: - change signed off line - add CONFIG_SAVE_PREV_BL_FDT_ADDR. It's needed to boot android stock kernel - change bootcmd to source bootscript from FIT image for more flexibility Changes for v3: - enable simple framebuffer - enable video console - add preboot variable - remove 0x prefix in name in device tree arch/arm/dts/starqltechn-uboot.dtsi | 9 ++++-- arch/arm/dts/starqltechn.dts | 13 ++++++-- configs/starqltechn_defconfig | 18 +++++++++-- doc/board/qualcomm/sdm845.rst | 47 ++++++++++++++++++++++++++++- include/configs/sdm845.h | 8 +++++ 5 files changed, 86 insertions(+), 9 deletions(-) diff --git a/arch/arm/dts/starqltechn-uboot.dtsi b/arch/arm/dts/starqltechn-uboot.dtsi index d8d75e018a..b55cccfe14 100644 --- a/arch/arm/dts/starqltechn-uboot.dtsi +++ b/arch/arm/dts/starqltechn-uboot.dtsi @@ -8,15 +8,18 @@ / { + framebuffer@9D400000 { + u-boot,dm-pre-reloc; + }; soc { u-boot,dm-pre-reloc; + serial@a84000 { + u-boot,dm-pre-reloc; + }; gcc { clock-controller@100000 { u-boot,dm-pre-reloc; }; - serial@0xa84000 { - u-boot,dm-pre-reloc; - }; gpio_north@3900000 { u-boot,dm-pre-reloc; }; diff --git a/arch/arm/dts/starqltechn.dts b/arch/arm/dts/starqltechn.dts index 387420f30b..0261388319 100644 --- a/arch/arm/dts/starqltechn.dts +++ b/arch/arm/dts/starqltechn.dts @@ -34,9 +34,18 @@ method = "smc"; }; + framebuffer: framebuffer@9D400000 { + compatible = "simple-framebuffer"; + reg = <0 0x9D400000 0 (2960 * 1440 * 4)>;//2400000 + width = <1440>; + height = <2960>; + stride = <(1440 * 4)>; + format = "a8r8g8b8"; + }; + soc: soc { - serial@0xa84000 { - status = "ok"; + serial@a84000 { + status = "okay"; }; pinctrl@3900000 { diff --git a/configs/starqltechn_defconfig b/configs/starqltechn_defconfig index f57bb859cc..c7d7514c66 100644 --- a/configs/starqltechn_defconfig +++ b/configs/starqltechn_defconfig @@ -2,13 +2,14 @@ CONFIG_ARM=y CONFIG_SKIP_LOWLEVEL_INIT=y CONFIG_POSITION_INDEPENDENT=y CONFIG_ARCH_SNAPDRAGON=y -CONFIG_SYS_TEXT_BASE=0x80000000 -CONFIG_SYS_MALLOC_LEN=0x81f000 CONFIG_DEFAULT_DEVICE_TREE="starqltechn" +CONFIG_BOOTDELAY=0 +CONFIG_FIT=y +CONFIG_FIT_VERBOSE=y CONFIG_TARGET_STARQLTECHN=y CONFIG_IDENT_STRING="\nSamsung S9 SM-G9600" CONFIG_SYS_LOAD_ADDR=0x80000000 -CONFIG_USE_PREBOOT=y +CONFIG_LMB_MAX_REGIONS=64 # CONFIG_DISPLAY_CPUINFO is not set CONFIG_HUSH_PARSER=y CONFIG_CMD_GPIO=y @@ -22,3 +23,14 @@ CONFIG_DM_PMIC=y CONFIG_PMIC_PM8916=y CONFIG_MSM_GENI_SERIAL=y CONFIG_SPMI_MSM=y +CONFIG_LINUX_KERNEL_IMAGE_HEADER=y +CONFIG_SAVE_PREV_BL_INITRAMFS_START_ADDR=y +CONFIG_SAVE_PREV_BL_FDT_ADDR=y +CONFIG_DM_VIDEO=y +CONFIG_VIDEO_LOGO=y +CONFIG_CMD_VIDCONSOLE=y +CONFIG_CONSOLE_NORMAL=y +CONFIG_SYS_WHITE_ON_BLACK=y +CONFIG_VIDEO_DT_SIMPLEFB=y +CONFIG_VIDEO_SIMPLE=y +CONFIG_CMD_BMP=y diff --git a/doc/board/qualcomm/sdm845.rst b/doc/board/qualcomm/sdm845.rst index cd46cbe9cf..b00a30a313 100644 --- a/doc/board/qualcomm/sdm845.rst +++ b/doc/board/qualcomm/sdm845.rst @@ -17,7 +17,9 @@ It is loaded as an Android boot image through ABL Installation ------------ -First, setup ``CROSS_COMPILE`` for aarch64.
