* ARM926EJS: Make asm routines volatile in cache opsMarek Vasut2012-04-161-1/+1
| | | | | | | | | | We certainly don't want the compiler to reorganise the code for dcache flushing.

* ARM: 926ejs: use debug() for misaligned addressesStefano Babic2012-04-161-1/+1
| | | | | | | | | | | | Misaligned warnings are useful to debug faulty drivers. A misaligned warning is printed also when the driver is correct - use debug() instead of printf().

* arm, arm-kirkwood: disable l2c before linux bootMichael Walle2012-02-121-0/+9
| | | | | | | | | | | The decompressor expects the L2 cache to be disabled. This fixes booting some kernels, which have CONFIG_ARM_PATCH_PHYS_VIRT enabled.

* arm926ejs: remove noop flush_dcache_all functionIlya Yanok2011-12-191-5/+0
| | | | | | | | | | | | | | | | Commit 2f3427c added noop cache functions implementation for arm926ejs to fix compilation of drivers depending on these functions (DaVinci EMAC in particular). Unfortunately, the bug was introduced: noop implementation calls dcache_disable which calls flush_dcache_all which in turn calls dcache_disable thus creating an infinite loop. This patch removes noop implementation for flush_dcache_all, we already have default one in arch/arm/lib/cache.c and it should be used instead.

* arm926ejs: add noop implementation for dcache opsIlya Yanok2011-12-061-0/+75
Added noop implementation for dcache operations that will buzz about missing real implementation and disable the dcache. This fixes compilation of DaVinci EMAC driver on arm926ejs. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
