hello.
i think you can run linux-3.0.4 kernel on your Ecovec (SH7724) board
in this debug-code.
void dma_cache_sync(struct device *dev, void *vaddr, size_t size,
enum dma_data_direction direction)
{
void *addr;
addr = __in_29bit_mode() ?
- (void *)CAC_ADDR((unsigned long)vaddr) : vaddr;
+ (void *)P1SEGADDR((unsigned long)vaddr) : vaddr;
CAC_ADDR((unsigned long)vaddr) : vaddr;
must be fail.
