* armv7: adapt omap4 to the new cache maintenance frameworkAneesh V2011-07-04-1/+22
| | | | | | adapt omap4 to the new layered cache maintenance framework Signed-off-by: Aneesh V <aneesh@ti.com>
* armv7: add PL310 support to u-bootAneesh V2011-07-04-0/+189
| | | | | | | | | | | | | PL310 is the L2$ controller from ARM used in many SoCs including the Cortex-A9 based OMAP4430 Add support for some of the key PL310 operations - Invalidate all - Invalidate range - Flush(clean & invalidate) all - Flush range Signed-off-by: Aneesh V <aneesh@ti.com>
* arm: minor fixes for cache and mmu handlingAneesh V2011-07-04-2/+18
| | | | | | | | | | | 1. make sure that page table setup is not done multiple times 2. flush_dcache_all() is more appropriate while disabling cache than a range flush on the entire memory(flush_cache()) Provide a default implementation for flush_dcache_all() for backward compatibility and to avoid build issues. Signed-off-by: Aneesh V <aneesh@ti.com>
* armv7: integrate cache maintenance supportAneesh V2011-07-04-32/+51
| | | | | | | | | | - Enable I-cache on bootup - Enable MMU and D-cache immediately after relocation - Do necessary initialization before enabling d-cache and MMU - Changes to cleanup_before_linux() - Make changes according to the new framework Signed-off-by: Aneesh V <aneesh@ti.com>
* armv7: rename cache related CONFIG flagsAneesh V2011-07-04-12/+7
| | | | | | | | | | | | | | | | Replace the cache related CONFIG flags with more meaningful names. Following are the changes: CONFIG_L2_OFF -> CONFIG_SYS_L2CACHE_OFF CONFIG_SYS_NO_ICACHE -> CONFIG_SYS_ICACHE_OFF CONFIG_SYS_NO_DCACHE -> CONFIG_SYS_DCACHE_OFF Signed-off-by: Aneesh V <aneesh@ti.com> V2: * Changed CONFIG_L2_OFF -> CONFIG_SYS_NO_L2CACHE V4: * Changed all three flags to the final names suggested as above and accordingly changed the commit message
* armv7: cache maintenance operations for armv7Aneesh V2011-07-04-1/+518
| | | | | | | | | | | | | | | | | | | | | | | | | | - Add a framework for layered cache maintenance - separate out SOC specific outer cache maintenance from maintenance of caches known to CPU - Add generic ARMv7 cache maintenance operations that affect all caches known to ARMv7 CPUs. For instance in Cortex-A8 these opertions will affect both L1 and L2 caches. In Cortex-A9 these will affect only L1 cache - D-cache operations supported: - Invalidate entire D-cache - Invalidate D-cache range - Flush(clean & invalidate) entire D-cache - Flush D-cache range - I-cache operations supported: - Invalidate entire I-cache - Add maintenance functions for TLB, branch predictor array etc. - Enable -march=armv7-a so that armv7 assembly instructions can be used Signed-off-by: Aneesh V <aneesh@ti.com>

* | powerpc/fsl_pci: Fix device tree fixups for newer platformsKumar Gala2011-05-20-1/+14
|/ | | | | | | | | | | | We assumed that only a small set of compatiable strings would be needed to find the PCIe device tree nodes to be fixed up. However on newer platforms the simple rules no longer work. We need to allow specifying the PCIe compatiable string for each individual SoC. We introduce CONFIG_SYS_FSL_PCIE_COMPAT for this purpose and set it if the default isn't sufficient. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
