From 2a636d15217cd326b4546e7017538c7a9e9d399c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 18 Jul 2012 18:02:43 +0200 Subject: Add MXS bootlets package MXS platforms (imx23 and imx28) are relying on bootlets as their first stage bootloaders, that can then either start a regular second stage bootloader or directly a Linux kernel. However, the Makefile allows only to build u-boot and linux images at the same time, which is not very convenient as we will more likely use only one of them, so we need to duplicate a bit what is already done so that we are able to choose what we want to generate. thomas.petazzoni@free-electrons.com: * Remove incorrect dependency on BR2_PACKAGE_ELFTOSB * Each board configuration option is for one board, not multiple boards, so use singular. * The i.MX28 support is for i.MX28 EVK only, reflect that in the option prompt and the option name. * Use 'generic-package' instead of GENTARGETS Signed-off-by: Maxime Ripard Signed-off-by: Thomas Petazzoni --- boot/Config.in | 1 + boot/common.mk | 2 +- boot/mxs-bootlets/Config.in | 90 +++++++++++++++++++++++++++++++++ boot/mxs-bootlets/barebox_ivt.bd | 34 +++++++++++++ boot/mxs-bootlets/mxs-bootlets.mk | 103 ++++++++++++++++++++++++++++++++++++++ 5 files changed, 229 insertions(+), 1 deletion(-) create mode 100644 boot/mxs-bootlets/Config.in create mode 100644 boot/mxs-bootlets/barebox_ivt.bd create mode 100644 boot/mxs-bootlets/mxs-bootlets.mk (limited to 'boot') diff --git a/boot/Config.in b/boot/Config.in index f8ab1cff5..5252a49a2 100644 --- a/boot/Config.in +++ b/boot/Config.in @@ -5,6 +5,7 @@ source "boot/at91dataflashboot/Config.in" source "boot/barebox/Config.in" source "boot/grub/Config.in" source "boot/lpc32xxcdl/Config.in" +source "boot/mxs-bootlets/Config.in" source "boot/syslinux/Config.in" source "boot/uboot/Config.in" source "boot/xloader/Config.in" diff --git a/boot/common.mk b/boot/common.mk index dc0bfb496..b315fe839 100644 --- a/boot/common.mk +++ b/boot/common.mk @@ -1 +1 @@ -include boot/*/*.mk \ No newline at end of file +include boot/*/*.mk diff --git a/boot/mxs-bootlets/Config.in b/boot/mxs-bootlets/Config.in new file mode 100644 index 000000000..2222ff607 --- /dev/null +++ b/boot/mxs-bootlets/Config.in @@ -0,0 +1,90 @@ +config BR2_TARGET_MXS_BOOTLETS + bool "mxs-bootlets" + depends on BR2_arm + help + Stage1 bootloaders for Freescale iMX23/iMX28 SoCs + +if BR2_TARGET_MXS_BOOTLETS + +choice + prompt "Source" + default BR2_TARGET_MXS_BOOTLETS_FREESCALE + help + Select the location of the bootlets you want to use + +config BR2_TARGET_MXS_BOOTLETS_FREESCALE + bool "Freescale 10.12.01 version" + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_TARBALL + bool "Custom tarball" + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_GIT + bool "Custom Git repository" + +endchoice + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_TARBALL_URL + depends on BR2_TARGET_MXS_BOOTLETS_CUSTOM_TARBALL + string "URL of custom bootlets tarball" + +if BR2_TARGET_MXS_BOOTLETS_CUSTOM_GIT + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_GIT_URL + string "URL of custom Git repository" + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_GIT_VERSION + string "Custom Git version" + +endif + +choice + prompt "Bootstream" + help + Select which bootstream to generate + +config BR2_TARGET_MXS_BOOTLETS_BAREBOX + depends on BR2_TARGET_BAREBOX + bool "Barebox Bootloader" + +config BR2_TARGET_MXS_BOOTLETS_LINUX + depends on BR2_LINUX_KERNEL + bool "Linux Kernel" + +config BR2_TARGET_MXS_BOOTLETS_UBOOT + depends on BR2_TARGET_UBOOT + bool "U-boot bootloader" + +endchoice + +config BR2_TARGET_MXS_BOOTLETS_HAS_IVT + bool "HAB Support" + help + Enable this option if you are building bootlets + for the iMX28 platform that needs to include instructions + for the secure boot mechanism present on these SoCs + +choice + prompt "Board" + help + Select the board to build the bootlets for + +config BR2_TARGET_MXS_BOOTLETS_STMP37xx + bool "Sigmatel ST-MP3-7xx Board" + +config BR2_TARGET_MXS_BOOTLETS_STMP378x + bool "Sigmatel ST-MP3-78x Board" + +config BR2_TARGET_MXS_BOOTLETS_IMX28EVK + bool "Freescale iMX28 EVK Board" + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_BOARD + bool "Custom board" +endchoice + +config BR2_TARGET_MXS_BOOTLETS_CUSTOM_BOARD_NAME + string "Custom board name" + depends on BR2_TARGET_MXS_BOOTLETS_CUSTOM_BOARD + help + Name of the board to build the bootlets for + +endif diff --git a/boot/mxs-bootlets/barebox_ivt.bd b/boot/mxs-bootlets/barebox_ivt.bd new file mode 100644 index 000000000..e02ddd68f --- /dev/null +++ b/boot/mxs-bootlets/barebox_ivt.bd @@ -0,0 +1,34 @@ +// STMP378x ROM command script to load and run U-Boot + +sources { + power_prep="./power_prep/power_prep";
