2011-07-04armv7: adapt omap4 to the new cache maintenance frameworkAneesh V
adapt omap4 to the new layered cache maintenance framework Signed-off-by: Aneesh V <aneesh@ti.com>
2011-07-04armv7: add PL310 support to u-bootAneesh V
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>
2011-07-04arm: minor fixes for cache and mmu handlingAneesh V
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>
2011-07-04armv7: integrate cache maintenance supportAneesh V
- 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>
2011-07-04armv7: rename cache related CONFIG flagsAneesh V
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
2011-07-04armv7: cache maintenance operations for armv7Aneesh V
- 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>

2011-05-11Kirkwood: allow to override CONFIG_SYS_TCLKSimon Guinot
This patch allow to override CONFIG_SYS_TCLK from board configuration files. This is needed for the Network Space v2 which use a non standard core clock frequency (166MHz instead of 200MHz for a 6281 SoC). As a possible enhancement for 6281 and 6282 devices, TCLK could be dynamically detected by checking the Sample at Reset register bit 21. Additionally this patch fix a typo.

2011-04-30Handle most LDSCRIPT setting centrallyScott Wood
Currently, some linker scripts are found by common code in config.mk. Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is sometimes in arch config.mk and sometimes in board config.mk. Some are found using an arch-specific rule for looking in CPUDIR, etc. Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds. Replace all of this -- except for a handful of boards that are actually selecting a linker script in a unique way -- with centralized ldscript finding. If board code specifies LDSCRIPT, that will be used. Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used. If neither of these are specified, then the central config.mk will check for the existence of the following, in order: $(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT) $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds $(TOPDIR)/$(CPUDIR)/u-boot.lds Some boards (sc3, cm5200, munices) provided their own u-boot.lds that were dead code, because they were overridden by a CPUDIR u-boot.lds under the old powerpc rules. These boards' own u-boot.lds have bitrotted and no longer work -- these lds files have been removed. Signed-off-by: Scott Wood <scottwood@freescale.com> Tested-by: Graeme Russ <graeme.russ@gmail.com>
