incorrect since itss is a child of p2sb which itself needs to probe the

the DRAM Controller in i.MX8MP will support a feature called "Inline ECC".
This is supported for all 3 supported DRAM technologies (LPDDR4, DDR4 and
DDR3L). When this feature is enabled by software, the DRAM Controller
reserves 12.5% of DRAM capacity for ECC information, and presents only
the non-ECC portion (lower 87.5% of the installed capacity of DRAM) to
the rest of the SoC.
The DRAM memory can be divided into 8 regions so that if a use case only
requires ECC protection on a subset of memory, then only that subset of
memory need support inline ECC. If this occurs, then there is no
performance penalty accessing the non-ECC-protected memory (no need to
access ECC for this portion of the memory map). This is all configured
with the DRAM Controller.

This patch extends dtoc to use struct driver_info when populating

In order to prepare for a new support of phandle when OF_PLATDATA is used
drop the const for struct driver_info as this struct will need to be
updated on runtime.

Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.
To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.
In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

(defaulting to CPHA=1) and CPOL=1 was hardcoded.

In current code there is no cache flush after initializing the scratchpad
buffer array with the scratchpad buffer pointers. This leads to a failure
of the "slot enable" command on the rpi4 board (Broadcom STB PCIe
controller + VL805 USB hub) - the very first TRB transfer on the command
ring fails and there is a timeout while waiting for the command completion
event. After adding the missing cache flush everything seems to be working
as expected.

Since the mdio code got upstreamed it is not possible
to activate network ports on CP110 Master and Slave.
The problem is in mvpp2_base_probe which is called for each
CP110 and it initializes the buffer area for descs and rx_buffers.
This should only happen once though and the bd space is actually
set to 0 after the first run of the function.
This leads to an error when the second CP110 tries the initialization
again and disables all network ports on this CP110.
This patch adds a static variable to check if the buffer area is
initialized only once globally.
