mmc: sdhci: fix missing cache invalidation after reading by DMA
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.

Currently, sdhci_prepare_dma() calls flush_cache() regardless of the

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

The reference manuals for MPC8308 and MPC8309 both say that the

System configuration registers. Unfortunately, that doesn't mean that
the registers are just mirrors of each other - any write to esdhcctl
is simply ignored. So to actually enable cache snooping, we
unfortunately have to add a little ifdeffery.
There is, naturally, no description of the bit fields of esdhcctl in
the MPC8309 manual, but comparing the description of esdhcctl from the
LS1021A reference manual to the description of the sdhccr in MPC8309,

Cadence sent out an errata report to their customers of this IP.
This errata is not so severe, but the tune request should be sent

Quote from the report:
Problem Summary
---------------
The IP6116 SD/eMMC PHY design has a timing issue on receive data path.
This issue may lead to an incorrect values of read/write pointers of
the synchronization FIFO. Such a situation can happen at the SDR104
and HS200 tuning procedure when the PHY is requested to change a phase
of sampling clock when moving to the next tuning iteration.
Workarounds
-----------
The following are valid workarounds to resolve the issue:
1. In eMMC mode, software sends tune request twice instead of once at
each iteration. This means that the clock phase is not changed on
the second request so there is no potential for clock instability.
2. In SD mode, software must not use the hardware tuning and instead
perform an almost identical procedure to eMMC, using the HRS34 Tune
Force register.
