cbabe7f87f configs: Migrate and re-enabled CONFIG_CMD_MTDPARTS
Now that CMD_UBI does not select CMD_MTDPARTS we need to make platforms
that had been enabling it turn it on by hand.  This exposed that we had
not yet migrated CMD_MTDPARTS fully, so do so now.

1f758b7936 mtd: Drop duplicate MTD_PARTITIONS Kconfig option
Commit 9c5b00973b ("Convert CONFIG_MTD_PARTITIONS et al to Kconfig")
introduced a publicly visible Kconfig entry for the
CONFIG_MTD_PARTITIONS option, while the rework on MTD partitioning
was in progress, and we somehow did not notice that the same Kconfig
entry was added by commit 4048a5c519 ("mtd: declare MTD_PARTITIONS
symbol in Kconfig"), but this time as an invisible entry (this can
only be selected by other options).

Keep the non-visible version of this symbol, since MTD_PARTITIONS is
not something the user should be able to enable/disable directly.

86dfa556d9 cmd: ubi: Remove useless call to mtdparts_init()
Commit c58fb2cdb3 ("cmd: ubi: clean the partition handling")
introduced a call to mtd_probe_devices() in the ubi_attach() path
and this function takes care of parsing mtdparts/mtdids and
creating/registering the associated mtd partitions.

The mtdparts_init() call in the ubi_detach() path is not only
unnecessary but can sometimes print error messages even when things
work properly (that's the case with SPI NAND devices that have not
been probed with 'mtd list'), which is misleading.

Remove this call to mtdparts_init() and drop the dependency on
CMD_MTDPARTS.

03303fb715 mtd: Make {MTDIDS, MTDPARTS}_DEFAULT visible when MTD_PARTITIONS is selected
gwventana configs are relying on CMD_UBI to select CMD_MTDPARTS,
which is then making {MTDIDS,MTDPARTS}_DEFAULT options available.

We are about to remove the 'select CMD_MTDPARTS' statement in the
CMD_UBI entry, but if we do that without first making sure
{MTDIDS,MTDPARTS}_DEFAULT are visible, we end up with a build
failure when building gwventana configs.

Address that by adding a depends on MTD_PARTITIONS to
{MTDIDS,MTDPARTS}_DEFAULT which does the trick since CMD_UBI selects
MTD_UBI which in turn selects MTD_PARTITIONS.

We also get rid of the depends on CMD_MTD, since CMD_MTD also selects
MTD_PARTITIONS.

5ffcd50612 mtd: Use default mtdparts/mtids when not defined in the environment
U-boot provides a mean to define default values for mtdids and mtdparts
when they're not defined in the environment. Patch mtd_probe_devices()
to use those default values when env_get("mtdparts") or
env_get("mtdids") return NULL.

This implementation is based on the logic found in cmd/mtdparts.c.

43e6f94cbc imx: mkimage: add size check to the u-boot.imx make target
The make macro to check if the binary exceeds the board size limit is
taken straight from the root Makefile.

Without this and e.g. enabled EFI Vybrid fails booting as the regular
size limit check does not take the final u-boot.imx binary size into
account which is bigger due to alignment as well as IMX header stuff.

a8483505e8 arm: mvebu: Move PCI(e) MBUS window to end of RAM
With patch 49b23e035d (pci: mvebu: Increase size of PCIe default mapping)
the mapping size for each PCI(e) controller was increased from 32MiB to
128MiB. This leads to problems on boards with multiple PCIe slots / ports
which are unable to map all PCIe ports, e.g. the Armada-XP theadorable:

DRAM:  2 GiB (667 MHz, 64-bit, ECC not enabled)
SF: Detected m25p128 with page size 256 Bytes, erase size 256 KiB, total 16 MiB
Cannot add window '4:f8', conflicts with another window
PCIe unable to add mbus window for mem at f0000000+08000000
Model: Marvell Armada XP theadorable

This patch moves the base address for the PCI(e) memory spaces from
0xe8000000 to the end of SDRAM (clipped to a max of 0xc0000000 right now).
This gives move room and flexibility for PCI(e) mappings.

9630146411 MIPS: make size of relocation table fixed but configurable
Currently the size of the relocation table will be shrunk
to the actual size needed. Although this gives a maximal
space saving, it messes up the _end symbol. This breaks
features like appended DTBs because the _end symbol doesn't
point to the real end of the U-Boot binary.

Remove the size shrinking and make the size of the relocation
table fixed but configurable. This follows the Linux approach
and the user can adjust the size to his needs.

Also rename the relocation table section from .rel to .data.reloc
to follow the Linux approach and to avoid ambiguities with the
.rel.* sections added by the linker.

2fc10754d1 mmc: tmio: sdhi: Implement waiting for DAT0 line state
When the bus switches to 1.8V mode of operation, it is necessary to
verify that the card correctly initiated and completed the voltage
switch. This is done by reading out the state of DATA0 line.

This patch implement support for reading out the state of the DATA0
line, so the MMC core code can correctly switch to 1.8V mode.

Add check to avoid touching the SCC tuning registers in case the IP
doesn't support them or if the support isn't in place yet.

c83da2ebc0 mmc: tmio: Preinitialize regulator to 3.3V
Preinitialize the SD card signals regulator to 3.3V, which is the
default post-reset setting, to be sure the regulator is set to a
valid value.

8171f99e7d mmc: tmio: Configure clock before any other IOS
Configure the clock settings before reconfiguring any other IO settings.
This is required when the clock must be stopped before changing eg. the
pin configuration or any of the other properties of the bus. Running the
clock configuration first allows the MMC core to do just that.
