We now use second level page tables which allows us to remap the dma coherent area dynamically. We don't have to map our sdram twice anymore which helps us on newer systems with big memory. As a bonus there is no board specific MMU code anymore. All a board has to do to enable MMU support is to register its SDRAM banks and call mmu_init(). Sascha Hauer (7): ARM cache l2x0: depend on MMU ARM: move armlinux_add_dram to location which is always compiled ARM l2x0: make init function static inline if l2 is not available ARM: pass size to dma_free_coherent ARM boards: move sdram setup before mmu setup ARM: rework MMU support ARM boards: remove now unnecessary mmu calls arch/arm/boards/chumby_falconwing/falconwing.c | 21 +-- arch/arm/boards/eukrea_cpuimx25/eukrea_cpuimx25.c | 28 +--- arch/arm/boards/eukrea_cpuimx27/eukrea_cpuimx27.c | 26 +-- arch/arm/boards/eukrea_cpuimx35/eukrea_cpuimx35.c | 25 +-- arch/arm/boards/eukrea_cpuimx51/eukrea_cpuimx51.c | 33 +--- arch/arm/boards/freescale-mx51-pdk/board.c | 28 +--- arch/arm/boards/guf-cupid/board.c | 22 +-- arch/arm/boards/guf-neso/board.c | 27 +--- arch/arm/boards/karo-tx25/board.c | 38 ++--- arch/arm/boards/karo-tx28/tx28.c | 21 +-- arch/arm/boards/panda/board.c | 18 +-- arch/arm/boards/pcm037/pcm037.c | 42 ++---- arch/arm/boards/pcm038/pcm038.c | 27 +-- arch/arm/boards/pcm043/pcm043.c | 25 +-- arch/arm/boards/pcm049/board.c | 21 +-- arch/arm/boards/phycard-i.MX27/pca100.c | 25 +-- arch/arm/boards/scb9328/env/config | 56 +++++++ arch/arm/cpu/Kconfig | 2 +- arch/arm/cpu/cpu.c | 14 ++ arch/arm/cpu/mmu.c | 177 +++++++++++++++++---- arch/arm/include/asm/armlinux.h | 7 +- arch/arm/include/asm/memory.h | 24 ++-- arch/arm/include/asm/mmu.h | 35 ++++- arch/arm/lib/armlinux.c | 19 +-- drivers/usb/gadget/fsl_udc.c | 2 +- include/common.h | 1 + 26 files changed, 396 insertions(+), 368 deletions(-) create mode 100644 arch/arm/boards/scb9328/env/config _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
