          There is a limitation with Denali DDRC Controller when ECC is enabled. It expects that the
          burst writes of greater than or equal to 16 bytes must start and end at a 16-byte boundary.
          Saying Y for this option will make the dma memory area to be non-writeable, apart from being
          non-cacheable so that single write should happen instead of burst.

	  ext4 partition, re-organize the splice code to gather all the memcpy calls in one place, instead
	  of allocating pages and releasing pipe buffers one by one. This improves performance and makes it
	  possible to use a DMA engine with scatter-gather in-place of mempcy.

config COMCERTO_HW_KERNEL_PAGETABLE

	  By default, Linux uses only one page table at a time, and switches page tables when switching
	  between processes. Say Y to enable the 2nd hardware page table, which will be used to map kernel
	  addresses.
	  Note that because of the way the ARM MMU determines which page table to use, this option can
	  only be enabled with a 2G/2G userspace/kernel memory split.

config COMCERTO_UNCACHED_DMA
	bool "Make pages uncacheable when doing DMA operations"
	depends on COMCERTO_HW_KERNEL_PAGETABLE
	default n
	help
	  When transferring ownership of a page to a device through the DMA API, make the page uncacheable
	  for the duration of the transfer. This makes the 2nd cache invalidate (that was needed because
	  of the possibility of speculative accesses by the A9 cores) unnecessary, which can increase
	  performance during heavy IO workloads. The page tables will be more complex though, resulting in
	  more TLB misses when a DMA transfer is going on.

config COMCERTO_SPLICE_READ_NOCONTIG
	bool "Use find_get_pages in splice read code"
	default n
	help
	  The splice read code normally calls find_get_pages_contig to retrieve pages mapping the requested
	  portion of the file to read. However, using find_get_pages works just as well, as the splice code
	  is able to handle both situations.
	  Say Y to use find_get_pages instead of find_get_pages_contig, which seems to yield a significant
	  performance improvement in Samba read tests.
