xea: config: Disable CONFIG_SPL_OF_PLATDATA_PARENT on XEA (imx28)
On the XEA board (imx28) one needs in the SPL support for GPIO, MMC and
SPI. Two last ones are necessary for booting the device. The GPIO support
allows deciding which medium will be used. For example the GPIO DTS node
(gpio@0 at imx28.dtsi) has pinctrl parent (pinctrl@80018000) for which we
don't need driver asigned for correct operation.
In the spl/dts/dt-platdata.c the gpio@0 has index 4 and its parent -
pinctrl@80018000 has index 5.
In the bind_drivers_pass() function (at drivers/core/lists.c) call to
device_bind_by_name() for `fsl_imx23_pinctrl` returns -2, which is
expected.
With current setup - when the SPL_OF_PLATDATA_PARENT=y
The gpio@0 node with index 4 is skipped as its parent with 5 is not yet
bound. It cannot be as we don't need and provide the driver for it.
As a result the gpio@0 is never bound and we end up with bricked board in
the SPL stage.
When CONFIG_SPL_OF_PLATDATA_PARENT is NOT set, all entries from
spl/dts/dt-platdata.c are scanned in ascending index order, so gpio@0 is
properly initialized. For `fsl_imx_pinctrl` we simply check 10 times if
the driver for is available (which is not) and exit.
As a result the GPIOs are initialized and can be used in early SPL stage.
