[PATCH 00/12] stm32mp1: use U-Boot device tree to configure MTD partitions

[Patrick Delaunay]

Add the MTD partitions subnode in U-Boot device tree for all stm32mp13
and stm32mp15 boards and no more rely on mtdids and mtdparts variables
or CONFIG_SYS_MTDPARTS_RUNTIME.

When these variables are absent, the required OF fallback is performed in
mtd_probe_devices() with commit dc339bf784f0 ("mtd: add support for parsing
partitions defined in OF").

To allow dynamically configuration of MTD partitioning for Linux kernel,
the MTD partitioning is only defined in U-Boot device tree and copied
in Linux kernel device tree.

This serie also disable CMD_MTDPARTS as it is strongly encouraged to
no more use this command.

Marek, I modify the dhcom/dhcor boardd in the last patch of the serie
but if you prefer I can drop this patch.

For "stm32mp157c-ev1-scmi.dts" the device tree file used by
stm32mp15_defconfig, with TF-A BL2 and OP-TEE including a SCMI server
for secure resources (when TZEN=1), the default STMicroelectronics
configuration.

I align the NOR and NAND layout on EV1 boards with the STMicroelectronics
recommendations used in OpenSTLinux V4.0:
with support of TF-A BL2 firmware update, required 2 "metadata" partition
for redundancy and 2 FIPs for A/B update.
