This workaround was previously needed for LD4, Pro4, sLD8, Pro5
SoCs. The boot ROM does not touch this register for PXs2/LD6b or
later.

Now that the reset signal of the Denali NAND controller is always
asserted in board_init() then deasserted in the driver, the
WRITE_PROTECT register gets back to the default value, which means
the write protect is deasserted.

This workaround can go away entirely.

The comment /* deassert reset */ is wrong. It asserts the reset.

It no longer needs to stay in SPL. The NAND controller reset is
handled  in the driver. So, this assert can be moved to the
board_init() of U-Boot proper.

This driver currently performs cache operation before the DMA start,
but does nothing after the DMA completion.

When reading data by DMA, the cache invalidation is needed also after
finishing the DMA transfer. Otherwise, the CPU might read data from
the cache instead of from the main memory when speculative memory read
or memory prefetch occurs.

Instead of calling the cache operation directly, this commit adds
dma_unmap_single(), which performs cache invalidation internally,
but drivers do not need which operation is being run.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Currently, sdhci_prepare_dma() calls flush_cache() regardless of the
DMA direction.

Actually, cache invalidation is enough when reading data from the device.

This is correctly handled by dma_map_single(), which mimics the DMA-API
in Linux kernel. Drivers can be agnostic which cache operation occurs
behind the scene.

This commit also sanitizes the difference between the virtual address
and the dma address.
