ARM: dts: stm32mp: align barebox dtsi name with upstream ...

Upstream has split stm32mp157c.dtsi into three files:

- stm32mp157.dtsi: GPU, DSI and stm32mp153.dtsi
- stm32mp153.dtsi: 2x CAN, 2nd Cortex-A7 and stm32mp151.dtsi
- stm32mp151.dtsi: everything else

Have our barebox specific fixup file follow the new naming scheme.

ARM: i.MX Phytec phycore i.MX27: replace __naked with noinline ...

phytec_phycore_imx27_common_init() doesn't need to be __naked, because
the stack has already been setup. What we want to have though is the
noinline attribute to make sure phytec_phycore_imx27_common_init() is
indeed a separate function which is called with initialized stack.

Basically the same as for i.MX8MQ, just some function split up needed
to account for different base addresses for the TF-A on both SoCs.

ARM: i.MX8M: Add DDR controller support ...

This adds the DDR driver for the i.MX8MQ/i.MX8MM. It's taken from
U-Boot v2020.04-rc1 with slight modifications for barebox

The i.MX8MQ boards in the tree currently use the output of an earlier
version of the NXP i.MX8M DDR Tool which doesn't use a controller driver
but instead does most stuff in board code. It seems this can coexist
with the new driver, only a few helper functions that previously lived
in arch/arm/mach-imx/imx8-ddrc.c are now provided by the new driver.

Tested on an i.MX8MM EVK

ARM: i.MX8MQ boards: Add missing includes ...

it directly.

ARM: i.MX8M: Add and use function for early UART clock setup ...

The i.MX8M boards all have the same code for setting up the UART clock.
Add a common helper for it. In the helper just setup the clocks for all
UARTs as it's not worth it to have separate functions for each UART.

ARM: i.MX8M: Add some lowlevel clock functions ...

U-Boot has some lowlevel clock functions which take a clock slice index

ARM: i.MX8M: rename imx8-ccm-regs.h to imx8m-ccm-regs.h ...

ARM: i.MX: Add SoC namespace to imx7/8m CCM defines ...

The CCM defines used on i.MX7 and i.MX8M do not have any SoC namespace.
Add it to make clear where they are supposed to be used. Since it looks
confusing to call i.MX7 specific defines on i.MX8M and vice versa,
duplicate them for both SoCs.

ARM: i.MX8M: rename functions to be i.MX8M specific ...

ARM: i.MX8M: rename i.MX8M specific function ...

The big i.MX8 variants have completely other UARTs than the i.MX8M

ARM: i.MX8M: Detect serial downloader mode correctly ...

like the i.MX6 the i.MX7 and i.MX8M also have a SBMR2 register which

ARM: i.MX8M: rename imx8_* bootsource functions to imx8mq_* ...

Those will differ between i.MX8MQ and i.MX8MM, so give them the
appropriate prefix before introducing i.MX8MM support.

ARM: i.MX8M: Use imx8mq.c for other i.MX8M as well ...

ARM: i.MX: Drop iomux argument from mx7_setup_pad() ...

The name mx7_setup_pad already implies the SoC where it runs on, so we
do not have to pass the iomux base address but can hardcode it in the
function. While at it rename it to imx7_setup_pad() which is more
consistent to other i.MX specific functions.

ARM: i.MX8M: add and use imx8mq_setup_pad() ...

We already have a mx8_setup_pad() function for early iomux setup, but it
is unused. Add a i.MX8MQ specific wrapper for the function which passes
the correct base address to mx8_setup_pad(). Let the boards use this
function. While at it rename mx8_setup_pad() to imx8_setup_pad() which
is more consistent to other i.MX specific functions.

ARM: i.MX8M: Add base addresses common to i.MX8M ...

This adds defines for the base addresses common to all currently
existing i.MX8M SoCs. Only the base addresses that are known to be
needed for the early SoC code are added. With this we can reuse the
early code for all variants without guessing that the base addresses
are the same for the other variants.
