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.

The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.
Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.
If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.
Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

The reference manuals for MPC8308 and MPC8309 both say that the
esdhcctl aka DMA Control Register "is implemented as SDHCCR" in 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,
one also finds that the fields are bit-reversed, so the bit to set is
0x02000000 rather than 0x00000040 - this is also what board_mmc_init()
uses in the two gdsys/mpc8308/ boards.

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
twice to avoid the potential issue.
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.

Remove fdt_high and initrd_high (set to 0xffffffff) in stm32mp1 board
enviromnent, and U-Boot always relocate FDT and initrd in bootm command.
This relocation is limited by CONFIG_SYS_BOOTMAPSZ which indicates
the size of the memory region where it is safe to place data passed
to the Linux kernel (DTB, initrd), it is
a) Less than or equal to RAM size.
b) not within the kernel's highmem region
So 256M seems large enough in most circumstances and users
can override this value via environment variable "bootm_mapsize"
if needed.
This modification increases the boot time but avoid assumption
on aligned address for bootm command.
A user can still define this variables themselves if the FDT or
initrd is either left in-place or copied to a specific location.
