* ARM: Allow to compile in thumb-2 modeSascha Hauer2012-03-061-0/+6
| | | | | | | | | This shrinks the resulting binary size by ~25%. Exceptions are still handled in arm mode, so we have to explicitely put .arm directives into the exception code. Thumb-2 mode has been tested on i.MX51 Babbage board. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * Add dump_stack functionSascha Hauer2012-01-261-0/+9
| | | | | | | | | | | | | | | | | | | | At least ARM allows us to dump the stack, but we currently have no prototype for this. Add a dump_stack prototype and provide a static inline function for architectures without stack dump support. Also, call dump_stack() in panic() to provide more information in the case of a panic.

* remove irq support fragmentsSascha Hauer2011-11-281-19/+0
| | | | | | | | We never had interrupt support in barebox and we have no plans to add interrupt support. Even if we do I doubt the current fragments of irq support are helpful, so remove them. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* pcm030: use new functionalitySascha Hauer2011-09-271-1/+1
| | | | | | | | | | We introduced several new functions to ease our life on ppc, use themn on the pcm030: - setup iomux and bus clocks in board code - add sdram memory according to detected size Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: rework MMU supportSascha Hauer2011-08-031-0/+1
| | | | | | | | | | | | | | | | | | In barebox we used 1MiB sections to map our SDRAM cachable. This has the drawback that we have to map our sdram twice: cached for normal sdram and uncached for DMA operations. As address space gets sparse on newer systems we are sometines unable to find a suitably big enough area for the dma coherent space. This patch changes the MMU code to use second level page tables. With it we can implement dma_alloc_coherent as normal malloc, we just have to remap the allocated area uncached afterwards and map it cached again after free(). This makes arm_create_section(), setup_dma_coherent() and mmu_enable() noops. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* move version_string to seperate fileSascha Hauer2011-04-111-0/+1
| | | | | | | | | In a noninteractive environment barebox will be compiled without command support. So move version_string to a seperate file which is compiled unconditionally. Also, display the banner when the simple console support is used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
