Currently the Serial Download Protocol tools and procedure are
documented in two places:- doc/imx/README.sdp
- doc/imx/README.imx6It is better to consolidate all SDP related information into
README.sdp file, so move the content from README.imx6 to
README.sdp.Signed-off-by: Breno Lima

When building i.MX8/8X board, use imx8image type.
`-e $(CONFIG_SYS_TEXT_BASE)` is not needed, but
no harm to keep it for i.MX8/8XSigned-off-by: Peng Fan

i.MX8/8X bootable image type is container type.
The bootable image, containers a container set which supports two

Add i.MX8 compatible string and cpu type support to lpuart driver,
to use little endian 32 bits configurations.Also, according to RM, the Receive FIFO Enable (RXFE) field in LPUART
FIFO register is bit 3, so this definition should change to 0x08
(not 0x40) for i.MX8, otherwise the Receive FIFO is not disabled.Signed-off-by: Peng Fan

Add the power domain DM driver for i.MX8, that it depends on the DTB
power domain trees to generate the power domain provider devices. Users
need to add power domain trees with property "compatible = "nxp,imx8-pd";"When power on a PD device, the driver will power on its ancestor PD
devices in power domain tree.When power off a PD device, the driver will check its child PD devices
first. Only if all child PD devices are off, then power off the current PD
device. Then the driver checks sibling PD devices. If sibling PD devices
are off, then it will power off parent PD device.There is no counter maintained in this driver, but a state to hold current
on/off state. So the request and free functions are empty.The power domain implementation in i.MX8 DTB set the "#power-domain-cells"
to 0, so there is no ID binding with each PD device. We don't use "id"
variable in struct power_domain. At the same time, we have to set of_xlate
to empty to bypass standard of_xlate in uclass driver.Signed-off-by: Peng Fan

Add pinctrl driver for i.MX8. The pads configuration is controlled
by SCU, so need to ask SCU to configure pads through scfw API.
Add pinctrl-scu to invoke sc_pad_set to configure pads.
Add a new flag IMX8_USE_SCU to differentiate i.MX8 from other platforms
which could directly configure pads from Acore side.
Add CONFIG_PINCTRL_IMX8 as the built gate.Signed-off-by: Peng Fan

add it to be able to display CPU info when CONFIG_DISPLAY_CPUINFO
option is enabled. CPU node in DT will have to include 'clocks'
