* common: add a macro to align an array on the stackAndre Heider2013-10-221-0/+11
| | | | | | | | | | | The macro can be used for temporary stack buffers which need to meet a minimum alignment requirement. This will be used by bcm2835 mailbox users, where all buffers need to be aligned. Signed-off-by: Andre Heider <a.heider@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * introduce barebox_set_modelSascha Hauer2013-08-161-0/+1
| | | | | | | | | | | | | | | | Instead of calling of_get_model() in barebox_get_model() add a barebox_set_model() and use it to set the boardinfo once it's available from the devicetree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * remove remaining references of CONFIG_BOARDINFOSascha Hauer2013-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | With this all code uses barebox_get_model() and no longer a compile time generated string. Also this renames barebox_boardinfo() to barebox_get_model() since we are going to add the corresponding _set_ function and 'model' corresponds to the devicetree notion.

* | startup: call a barebox_main function pointer at the end of the startupSascha Hauer2013-01-201-0/+6
|/ | | | | | | | | | | | | | | | | 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>

* | Change byte order detection mechanism to kernel styleSascha Hauer2012-06-281-0/+18
|/ | | | | | | | | | | | | | | The Linux Kernel defines only one of __LITTLE_ENDIAN and __BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then be tested with #if __BYTE_ORDER == __xx_ENDIAN. As we tend to use a lot of Kernel code in barebox we switch to use the kernel way of determing the byte order. As this always causes a lot of confusion add a check to include/common.h to make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined. 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>
