| * | Load PBL into SRAMDavid Vincent2014-02-091-1/+12
| |/ | | | | | | | | | | | | | | | | | | This allows to load all the lowlevel init code, including the uncompressor, inside SRAM and not just the bare init part. This is useful when pbl is used as a first-stage bootloader but is loaded by an external firmware.

| | | | | | | | | | | | | | | | | | | | | Our KEY_ defines conflict with the standard Linux KEY_ defines, so add a BB_ prefix to them. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | | defaultenv: Add boot option for DFUSascha Hauer2014-02-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DFU is for device firmware upgrade, but for development purposes it's sometmes useful to just start a kernel vie DFU. This adds a boot option for doing this and also the corresponding counterpart on the host. With this it's possible to boot a system with: scripts/dfuboot.sh -k linuximage -d dtb -c "root=ubi0:root ubi.mtd=ubi rootfstype=ubifs ignore_loglevel" Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | | defaultenv: Allow multiple defaultenvironment overlaysSascha Hauer2014-02-284-74/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can compile barebox for multiple boards at once, but currently they all share a single default environment. This patch adds a defaultenv_append() which boards can call to customize the default environment during runtime. Each board now generate default environment snippets using bbenv-y and add them during runtime with defaultenv_append() Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | | defaultenv: Align defaultenv arraySascha Hauer2014-02-202-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default environment buffer is an unsigned char array and thus may be unaligned. Some decompression algorithms expect the buffer to be sufficiently aligned for u32 accesses. We make this sure by copying the default env to a temporary buffer. Instead of doing this just add a __aligned(4) to the default environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of asking explicitly for the default environment compression type ask for the in-barebox default compression type. This also adds a DEFAULT_COMPRESSION_SUFFIX make variable which can be used together with the wildcard rules for compressed files to generate compressed files without explicitly support each compression type.

* | | defaultenv: simplify env dependenciesSascha Hauer2014-02-181-11/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finding out whether to rebuild the environment is a difficult task since we have to track all files in a directory. Instead of trying this, just rebuild the environment during every build and only if it differs to the last one overwrite the target. This way make only sees a change when the environment is changed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | default_environment_path only exists when CONFIG_ENV_HANDLING is enabled. Boards would have to #ifdef this if they wanted to use default_environment_path. Use accessor functions instead which can be ifdeffed on a single place.

| * | console: Set Linux console parameter automaticallySascha Hauer2014-01-221-1/+28
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux specifies the linux,stdout-path property in the /chosen node in the devicetree. Unfortunately this is ignored in most cases. For cases in which barebox uses this property for its own use we translate this into a Linux boot arg with: - the console name provided by the serial driver - the the instance from the 'serial' alias - the baudrate from the actual baudrate. So with this it's for devicetee enabled boards no longer necessary to manually assign a console= parameter. Should a user not want to use the automatically assigned parameter it should do: global.linux.bootargs.console= in the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ | | | | | | | | | The common bootm code used to load uImage contents to SDRAM before calling into the handlers if possible. This makes the handlers complicated since they have to handle many cases. Instead, introduce a helper to load the os after the handlers have figured out a good load address.

| | | | | | | | | | | | | | | | | | Sometimes execution of a function has to be delayed, for example when a backlight can only be turned on when the picture has stabilized.
