| * ARM: Add relocatable binary supportSascha Hauer2013-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For making the same binary executable on different SoCs which have different DRAM addresses we have to be independent of the compile time link address. This patch adds relocatable binary support for the ARM architecture. With this two new functions are available. relocate_to_current_adr will fixup the binary to continue executing from the current position. relocate_to_adr will copy the binary to a given address, fixup the binary and continue executing from there. For the PBL and the real image relocatable support can be enabled independently. This is done to (hopefully) better cope with setups where the PBL runs from SRAM or ROM and the real binary does not.

* | defaultenv-2: add boot sequenceJean-Christophe PLAGNIOL-VILLARD2013-03-051-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | This allows to boot a sequence of boot entries until one succeeds. boot sources can be passed in $global.boot.default, which is now treated as a list. Also a list of boot entries can be specified as arguments to the boot script. The entries can be: - a plain filename from /env/boot/ - a full path to an arbitrary file - a directory containing boot entries With this this command: boot net nand-ubi /env/boot.d would first use the /env/boot/net entry, if this fails the /env/boot/nand-ubi entry and if this also fails the files from /env/boot.d/ (which could also be links to boot scripts) To make the above the default, global.boot.default would be specified as: global.boot.default="net nand-ubi /env/boot.d" Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: Enable mmu earlySascha Hauer2013-02-041-0/+9

* | startup: call a barebox_main function pointer at the end of the startupSascha Hauer2013-01-201-6/+2
|/ | | | | | | | | | | | | | | | | Currently Kconfig dependencies are used to allow non-interactive builds. This leads to problems in Kconfig getting the dependencies right. This patch adds a barebox_main function pointer which is called at the end of the startup process. This defaults to run_shell when a shell is enabled. With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive builds can now be enabled for every board allowing to compile a binary without further Kconfig dependencies. This also allows for more flexibility, for example boards may decide to try non-interactive startup first and call run_shell if that fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in-system update means to write an arbitrary file to an arbitrary device. There is no sanity check if the flashed image is of the right type or will fit onto the device. Furthermore some SoCs need a special preparation step for their images before flashing them. This adds a barebox in-system update infrastructure. Boards can register update handlers which know how to make the board bootable. The available handlers can be listed to be able to select one, different force levels give the user the chance to know it better. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add next generation default environment templateSascha Hauer2012-05-181-3/+16
| | | | | | | | | | | | | | | | | | | | This adds a new environment template which aims to be more flexible and configurable. Instead of having mainly two scripts (a config script and a boot script) this template uses initscripts which control the startup behaviour and configuration. Also we have boot scripts in /env/boot which configure a single boot configuration. Additional boot entries can be added by board specific entries or during runtime by copying and editing a template entry. Some more helpers handle for example network interfaces which can now be brought up with 'ifup'. We use the automount feature to configure mountpoints together with the commands to bring up the devices behind these mountpoints. Optionally menu support is available which hides many details behind a nice looking interface. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
