* 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>

* include/linux/stat.h: make struct stat unifiedAntony Pavlov2011-06-281-58/+0
| | | | | | | | | | | | | The current version of struct stat has been taken from an ancient Linux Kernel.

| | | | | | | | | | | | | | | | | | While getting rid of all the format(barebox_printf) warnings was nice, it caused the printf calls in arch/sandbox/os/common.c to get directed to the barebox versions rather than the libc ones causing a crash: E.G. before this revert: nm -a barebox|grep -w printf 0000000000404fa3 T print And after: nm -a barebox|grep -w printf U printf@@GLIBC_2.2.5 Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> This reverts commit 6b082cfe9f9b5b2bea294918ad916c739490cea7.
