This is particulary usefull for the few devices mapped at physical address 0, as the MTD boot devices.

2011-08-03	3100ea1 Browse files » ARM: rework MMU support ... 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> Sascha Hauer committed on 3 Aug 2011

2011-01-07	c5baa0e Browse files » Fix error handling with malloc, memalign etc. Introduce xmemalign(). ... The idea is to panic() when there is no memory available for normal operation. Exception: code which can consume arbitrary amount of RAM (example: files allocated in ramfs) must report error instead of panic(). This patch also fixes code which didn't check for NULL from malloc() etc. Usage: malloc(), memalign() return NULL when out of RAM. xmalloc(), xmemalign() always return non-NULL or panic().
