ARM: at91: dts: sama5d27-som1: adapt to upstream partition layout ...

Linux v5.8-rc1 adds partitions to the flash@0 node, which now overlap
with the partitions we define and resulting in errors:

  ERROR: m25p0.barebox: New partition m25p0.barebox conflicts
	with m25p0.at91bootstrap
  ERROR: m25p0.barebox-environment: New partition
  	m25p0.barebox-environment conflicts with m25p0.bootloader

We don't want to reuse those partitions as their name may and probably
will change (they have leading zeroes in the unit address).
We could use the &{/path/to/partition} syntax, but that might be broken
soon as well, as the nodes aren't inside a partitions node with a
"fixed-partitions" compatible.
The busses also don't align with the yaml schema and might be renamed.

Nuke the full flash@0 node and supply ours and avoid these problems.
The offsets of the partitions have been adjusted to coincide with the
upstream offsets for second stage bootloader and environment.

ARM: at91: sama5d2: populate $bootsource and $bootsource_instance ...

The BootROM passes us information about the boot medium in r4 and we
already use that in first stage and pass it along to second stage
PBL already. To make use of it, we need to pass it to barebox proper, do
this by writing it in the last 4 bytes of the SRAM. As second stage
always run in DRAM, this is safe to do.

We could also write to SRAM directly from first stage, but at91bootstrap
passes info in r4 as well for the sama5d3 boards, so we do it likewise
to maintain compatibility.

ARM: at91: sama5d2: read back memory size from DDRAM controller ...

We hard code memory size at three places:
 - In the configuration we use to initialize the DDRAM controller
 - In the minimal available size passed from PBL to barebox proper
 - In the device tree memory node override

Remove the two latter ones and replace them with code that reads the
size back from controller.

mci: imx-esdhc-pbl: Add imx8mp_esdhc_load_image() for i.MX8MP ...

The image format of the i.MX8MP is different from i.MX8M, so add its own
image loading function for it.

Older i.MX SoCs had a IVT Offset (the offset from the start of the image
to the actual data) of 1KiB. This was done to leave space for the
partition table at the beginning of the device. To support GPT SoCs
starting with i.MX8M an additional gap of 32KiB was added, so that the
actual image started at offset 33KiB. Now starting with i.MX8MP the now
superfluous 1KiB offset was removed do that the actual image now starts
at 32KiB.
Unfortunately the 1KiB offset is woven into the offsets of the IVT
whereas the 32KiB are not, which means that we really have to handle
both offsets individually instead of just handling the sum of the
offsets.

ARM: at91: sama5d2: reduce UART setup boilerplate with new helpers ...

The sama5d2 can be fused for one of 9 preset UART iosets. This is then
used by the BootROM for printing the `RomBOOT' header and for the XMODEM
protocol implemented by the SAM-BA monitor. Add two new sama5d2 specific
helpers:

- sama5d2_dbgu_setup_ll for setting up the port with only pinmux and
  master clock as arguments
- sama5d2_resetup_uart_console for resetup of the uart console with
  same pinmux used by the ROM code

The default value, when unfused, is UART_1_IOSET_1 (RX@PD2, TX@PD3),
which are the same ones used on the two sama5d2 board supported so far.

With this change, the DEBUG_LL baudrate is also no longer fixed at 115200,
but instead comes from the CONFIG_BAUDRATE symbol.
