MTD partition creation code is a bit tricky. It tries to figure out
when things have changed (either MTD dev list or mtdparts/mtdids vars)
and when that happens it first deletes all the partitions that had been
previously created and then creates the new ones based on the new
mtdparts/mtdids values.
But before deleting the old partitions, it ensures that none of the
currently registered parts are being used and bails out when that's
not the case. So, we end up in a situation where, if at least one MTD
dev has one of its partitions used by someone (UBI for instance), the
partitions update logic no longer works for other devs.
Rework the code to relax the logic and allow updates of MTD parts on
devices that are not being used (we still refuse to updates parts on
devices who have at least one of their partitions used by someone).

The mtdparts variable might contain partition definitions for several
MTD devices. Each partition layout is separated by a ';', so let's
make sure we don't pick a wrong name when mtdparts is malformed.

spi_flash_mtd_register() can be called several times and each time it
will register the same mtd_info instance like if it was a new one.
The MTD ID allocation gets crazy when that happens, so let's track the

We need to parse mtdparts/mtids again everytime a device has been
added/removed from the MTD list, but there's currently no way to know
when such an update has been done.
Add an ->updated field to the idr struct that we set to true every time
a device is added/removed and expose a function returning the value
of this field and resetting it to false.

If U-Boot is started from SPL or TPL, then those earlier phases deal with

According to SD Specifications Part 1 Physical Layer Simplified Specification
Version 6.00 August 29, 2018, section 4.3.10 (Switch Function Command) and
section 5.6 (SCR register), SD cards version 1.00 and 1.01 do not support the
SD CMD 6.
Currently, U-Boot will issue CMD 6 unconditionally in sd_set_card_speed()
while configuring the bus for selected frequency. This will make SD cards
version 1.00 and 1.01 time out and thus fail detection altogether.
Fix this by not sending CMD 6 on such cards. Tested on Matsushita Electric
Industrial Co., Ltd. Japan RP-SD008B / Victor 8MB SD card, CU-SD008, which
is correctly detected with this patch as:
Device: sd@ee160000
Manufacturer ID: 1
OEM: 5041

This reverts commit 6f57c34473d37b8da5e6a3764d0d377d748aeef1 since it
does not seem to work at least on rk3399.
The Rockchip Technical Reference Manual (TRM) for the rk3399 says the baud
rate prescaler register is readable only when USR[0] is zero. Since this
bit is defined as "reserved" in the socfpga cylcone5 TRM, let's rather
drop this than making the ns16550 debug uart more platform specific.

This patch adds a DM driver for the MPC8xx watchdog.
Basically, the watchdog is enabled by default from the start and
SYPCR register has to be writen once to set the timeout and/or
deactivate the watchdog. Once written, it cannot be written again.
It means that wdt_stop() can be called before wdt_start() to stop the
watchdog, but cannot be called if wdt_start() has been called.

Reorder the tmio_sd_set_clk_rate() function such that it handles all
of the clock requiests correctly. Specifically, before this patch,
clock request with (mmc->clock == 0 && mmc->clk_disable) could leave
the clock enabled, as the function would exit on if (!mmc->clock)
condition on top and will not handle the mmc->clk_disable at all.
Rather than band-aid fixing just that particular problem, reorder
the entire function to make it easier to understand and verify that
all the cases are covered. The function has three sections now:
First, if mmc->clock != 0, we calculate divider for the SD block.
Second, if mmc->clock != 0 and SD block clock are enabled and
current divider is not equal to the new divider, then
stop the clock and update the divider.
Third, if mmc->clk_disable is set, disable the clock, otherwise
enable the clock. This happens independently of divider
update now.

The TMIO core has a feature where it can automatically disable clock output
when the bus is not in use. While this is useful, it also interferes with
switching the bus to 1.8V and other background tasks of the SD/MMC cards,
which require clock to be enabled.
This patch respects the mmc->clk_disable and only disables the clock when
the MMC core requests it. Otherwise the clock are continuously generated
on the bus.
