SUMMARY = "Initial bootstrap for AT91 ARM MPUs" DESCRIPTION = " \ at91bootstrap is the second-level bootloader for Atmel AT91 \ SoCs. It provides a set of algorithms to manage the hardware \ initialization and to download the main application (or a \ third-level bootloader) from specified boot media to \ main memory and start it. \ " AUTHOR = "Atmel Corporation" HOMEPAGE = "http://www.at91.com/linux4sam/bin/view/Linux4SAM/AT91Bootstrap" BUGTRACKER = "https://github.com/linux4sam/at91bootstrap/issues" SECTION = "bootloaders" LICENSE = "ATMEL" LIC_FILES_CHKSUM = "file://main.c;endline=27;md5=42f86d2f6fd17d1221c5c651b487a07f" inherit cml1 deploy SRC_URI_append = " \ file://defconfig \ file://onetime-slow-clock-switch.patch \ file://0003-disable-rtc-interrupts.patch \ file://at91sam9x5_4bit_pmecc_header.bin \ " SRC_URI_append_mtrv1 = " file://0001-mtrv1-DDRlowDriveStrength.patch \ file://defconfig.mtr \ file://0005-at91bootstrap-3.8-mtr.patch \ " SRC_URI_append_mtr = " file://defconfig.mtr \ file://0005-at91bootstrap-3.8-mtr.patch \ " SRC_URI_append_mtcdt = " file://0005-at91bootstrap-3.8-mtcdt.patch " SRC_URI_append_mtcap = " file://0005-at91bootstrap-3.8-mtcap.patch " DEPENDS += "bc-native" AT91BOOTSTRAP_MACHINE ??= "${MACHINE}" AT91BOOTSTRAP_CONFIG ??= "${AT91BOOTSTRAP_MACHINE}nf_uboot" AT91BOOTSTRAP_CONFIG_at91sam9x5ek-sd ??= "${AT91BOOTSTRAP_MACHINE}sd_uboot" AT91BOOTSTRAP_CONFIG_sama5d3-xplained-sd ??= "${AT91BOOTSTRAP_MACHINE}sd_uboot" AT91BOOTSTRAP_CONFIG_sama5d4ek ??= "${AT91BOOTSTRAP_MACHINE}nf_uboot_secure" AT91BOOTSTRAP_CONFIG_sama5d4-xplained ??= "${AT91BOOTSTRAP_MACHINE}nf_uboot_secure" AT91BOOTSTRAP_CONFIG_sama5d4-xplained-sd ??= "${AT91BOOTSTRAP_MACHINE}sd_uboot_secure" AT91BOOTSTRAP_CONFIG_sama5d2-xplained ??= "${AT91BOOTSTRAP_MACHINE}-bsrdf_uboot" AT91BOOTSTRAP_CONFIG_sama5d2-xplained-sd ??= "${AT91BOOTSTRAP_MACHINE}-bsrsd_uboot" AT91BOOTSTRAP_CONFIG_sama5d27-som1-ek ??= "${AT91BOOTSTRAP_MACHINE}qspi_uboot" AT91BOOTSTRAP_CONFIG_sama5d27-som1-ek-sd ??= "${AT91BOOTSTRAP_MACHINE}sd_uboot" AT91BOOTSTRAP_TARGET ??= "${AT91BOOTSTRAP_CONFIG}_defconfig" AT91BOOTSTRAP_LOAD ??= "nandflashboot-uboot" AT91BOOTSTRAP_LOAD_at91sam9x5ek-sd ??= "sdboot-uboot" AT91BOOTSTRAP_LOAD_sama5d2-xplained ??= "dataflashboot-uboot" AT91BOOTSTRAP_LOAD_sama5d2-xplained-sd ??= "sdboot-uboot" AT91BOOTSTRAP_LOAD_sama5d27-som1-ek ??= "qspiboot-uboot" AT91BOOTSTRAP_LOAD_sama5d27-som1-ek-sd ??= "sdboot-uboot" AT91BOOTSTRAP_LOAD_sama5d3-xplained-sd ??= "sdboot-uboot" AT91BOOTSTRAP_LOAD_sama5d4-xplained-sd ??= "sdboot-uboot" AT91BOOTSTRAP_SUFFIX ?= "bin" AT91BOOTSTRAP_IMAGE ?= "${AT91BOOTSTRAP_MACHINE}-${AT91BOOTSTRAP_LOAD}-${PV}.${PR}.${AT91BOOTSTRAP_SUFFIX}" AT91BOOTSTRAP_BINARY ?= "at91bootstrap.${AT91BOOTSTRAP_SUFFIX}" AT91BOOTSTRAP_SYMLINK ?= "at91bootstrap-${AT91BOOTSTRAP_MACHINE}.${AT91BOOTSTRAP_SUFFIX}" EXTRA_OEMAKE = 'CROSS_COMPILE=${TARGET_PREFIX} REVISION=${PR} CC="${TARGET_PREFIX}gcc ${TOOLCHAIN_OPTIONS}"' do_configure() { # Copy board defconfig to .config if .config does not exist.
