* Add multi images supportSascha Hauer2013-07-015-1/+165
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the make infrastructure to build multiple SoC or board specific images from a single barebox binary. The basic idea is that we no longer have a single pbl, but instead multiple pbls, one per image if necessary. Each pbl is defined by its entry function so that each pbl can do exactly what a given board needs. Additionally the pbls together with a self extracting barebox binary can be encapsulated in specific image formats. squashed in build fixes from Lucas Stach for make version >= 3.82: Split Multimage Makefile rule in explicit and implicit parts Fixes build with make version >=3.82 Frome the make 3.82 NEWS file: * WARNING: Backward-incompatibility! In previous versions of make it was acceptable to list one or more explicit targets followed by one or more pattern targets in the same rule and it worked "as expected". However, this was not documented as acceptable and if you listed any explicit targets AFTER the pattern targets, the entire rule would be mis-parsed. This release removes this ability completely: make will generate an error message if you mix explicit and pattern targets in the same rule.

* ARM: Add image end sectionSascha Hauer2013-06-262-1/+10
| | | | | | | | | | | In the upcoming multi image build process we will cat images together. To find the concatenated image we need to reliably find the end of the current binary. This adds a dummy section at the end of a pbl binary. Its only purpose is to mark the end of the image. The multi image patches will add something to this section so that it doesn't get discarded by the linker. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: build dtbs depending on CONFIG_OFTREESascha Hauer2013-06-261-1/+1
| | | | | | | | | The upcoming multi image support will need devicetree binary blobs even when there is no builtin dtb. Instead of depending on CONFIG_BUILTIN_DTB depend on CONFIG_OFTREE and let this option select DTC. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: pbl: move linker script to libSascha Hauer2013-06-262-2/+4
| | | | | | | | | Since the pbl linker script can be reused by the upcoming multi image build process move it to a common place. Also remove ENTRY() from the linker script and instead add the -e option to the linker. This makes the entrypoint configurable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: split barebox_arm_head in two separate functionsSascha Hauer2013-06-261-3/+11
| | | | | | | | | | | | This adds a new function __barebox_arm_head() which defines an the regular barebox ARM header, but which jumps to the end of the function so that this can be embedded into another function. barebox_arm_head() now just uses it and jumps to barebox_arm_reset_vector just like it did before. This makes it possible to define board specific entry points. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* OMAP4: fix omap4_bootsource regressionJan Weitzel2013-06-231-2/+2
| | | | | | | | | | commit d7a913469c34553e96c887f8a9934bacd794e81c breaks boot source detection for pcm049. The tracing vectors shows all tested boot sources, so order is important. By not returning but overwriting src we effectively reversed the order if more than one flag is set.

| | | | | | | | | | | | Set DEBUG_LL_UART_DIVISOR to use <asm/debug_ll_ns16550.h>. The JZ4755 uses 24 MHz as the main reference frequency (EXCLK). The UART controller can work on full EXCLK or on EXCLK/2. Just now we use EXCLK/2 legacy clock setup made by U-Boot. So set UART controller base frequency to 12 MHz.

| * tegra20: add generic board and Colibri T20 on IrisLucas Stach2013-05-154-0/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | The Tegra arch will be fully based on device tree and most boards shouldn't need anything more than the generic drivers and arch code. This adds generic tegra20 board support, but since we currently have no way to combine an image with a devicetree other than compiling it into the single image we also add Colibri T20 on Iris support here and add a defconfig for it.

The SoC internal ROM reads these GPIOs and uses the selected boot source. For various reasons the boot source is also of interest when Barebox is running. This detection approach reads again the GPIOs. It switches temporarily the pins to act as GPIOs and input, reads their settings, and switches back to their previous functions.
