Currently the ofdata_to_platdata() method calls dev_read_addr_pci(),
which potentially accesses the parent PCI bus. If this happens before
the parent PCI bus is probed the resulting address will be wrong.
This behavior was triggered by commit 82de42fa1468 ("dm: core:
Allocate parent data separate from probing parent").
According to a comment in drivers/pci/pci-uclass.c [1] accessing
the PCI parent bus in ofdata_to_platdata() is not allowed, and the
access should be moved to the probe() function.
Move the call to dev_read_addr_pci() and the related handling of the
'addr' value from the ofdata_to_platdata() to its own function,
which is then called from the probe() method.
While moving the code, the comment /* try Processor Local Bus device
first */ was dropped. It was initially added with commit 3db886a5bf38
("serial: ns16550: Support ns16550 compatible pci uart devices") and
later made obsolete with commit 33c215af4b9d ("dm: pci: Add a function
to read a PCI BAR").
[1] Comment in drivers/pci/pci-uclass.c:
"A common cause of this problem is that this function is called in the
ofdata_to_platdata() method of @dev. Accessing the PCI bus in that
method is not allowed, since it has not yet been probed. To fix this,
move that access to the probe() method of @dev instead."

When flow id is not marked as valid, sysfw reads the register value to
get the range of flow ids that are supported. Then compares the flow range
with the U-Boot's host id. This will definitely fail as board
configuration doesn't assign the full range to U-Boot's host id. In order
to work around this, mark the flow id as valid and pass range as 0.

Update the driver to support the device tree and the driver model.
Timings and panel parameters are now loaded from the device tree.
The DM code replaces the am335x_lcdpanel structure with
tilcdc_panel_info taken from the linux kernel, as well the management
of additional parameters not covered in the legacy code. In addition,
the am335x_lcdpanel structure contains parameters and operations that
were probably a requirement of the board for which this driver was
developed and which, however, were not developed in the linux kernel.
All this led to rewrite th DM controller initialization code, except
for the pixel clock setting that is executed in a function created in a
previous patch with code taken from the legacy am335xfb_init.
The patch has been tested on a custom board with u-boot 2018.11-rc2 and
the following device-tree configuration:
panel {
compatible = "ti,tilcdc,panel";
pinctrl-names = "default";
pinctrl-0 = <&lcd_enable_pins>;

The ESM (Error Signal Monitor) is used on certain PMIC versions to
handle error signals propagating from rest of the system. If these
reach the PMIC, it is typically a last resort fatal error which
requires a system reset. The ESM driver does the proper configuration
for the ESM module to reach this end goal. Initially, only TPS65941
PMIC is supported for this.

The ESM (Error Signaling Module) is used to route error signals within
the K3 SoCs somewhat similar to interrupts. The handling for these is
different though, and can be routed for hardware error handling, to
be handled by safety processor or just as error interrupts handled
by the main processor. The u-boot level ESM driver is just used to
configure the ESM signals so that they get routed to proper destination.

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
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.
