7e00e907f5 watchdog: Don't select CONFIG_WATCHDOG and CONFIG_HW_WATCHDOG at the same time
Commit 06985289d4 ("watchdog: Implement generic watchdog_reset()
version") introduced an automatic selection of CONFIG_WATCHDOG by
CONFIG_WDT. But for boards selecting CONFIG_HW_WATCHDOG, like
boards have a powerpc 8xx, CONFIG_WATCHDOG shall not be selected
as they are mutually exclusive.

Make CONFIG_WATCHDOG dependent on !CONFIG_HW_WATCHDOG

a68256074f watchdog: mpc8xx: Revert the 8xx watchdog back to CONFIG_HW_WATCHDOG
Commit f3729ba6e7 ("watchdog: mpc8xx_wdt: Watchdog driver and macros
cleanup") switched the watchdog to CONFIG_WATCHDOG. But this is not
compatible with the 8xx because it starts the watchdog HW timer at
reset and must be serviced from the very beginning including while
U-boot is executed in the firmware before relocation in RAM.

Select CONFIG_HW_WATCHDOG and make hw_watchdog_reset() visible.

Meanwhile, finalise the cleanup of arch/powerpc/cpu/mpc8xx/Kconfig by
removing the lines put in comment in that commit, and also remove
again the selection of CONFIG_MPC8xx_WATCHDOG which was removed by
that commit and brought back by mistake by commit b3134ffbd9
("watchdog: Kconfig: Sort entry alphabetically")

Note that there was an 'imply WATCHDOG' in the original commit but
it disappeared in the Kconfig alphabetical sorting, so no need to
remove it here.

1320fa2e55 ARM: uniphier: remove workaround for the NAND write protect
This workaround was previously needed for LD4, Pro4, sLD8, Pro5
SoCs. The boot ROM does not touch this register for PXs2/LD6b or
later.

Now that the reset signal of the Denali NAND controller is always
asserted in board_init() then deasserted in the driver, the
WRITE_PROTECT register gets back to the default value, which means
the write protect is deasserted.

This workaround can go away entirely.

8bef0597e4 defconfig: k2x_hs: Remove DTB_RESELECT to fix DHCP issue
This fixes the inadvertent definition of CONFIG_DTB_RESELECT and
CONFIG_MULTI_DTB_FIT in the K2x HS defconfigs, that happened as part of
a resync of the defconfigs.

The inclusion of these config options causes ethernet to stop working on
K2x HS devices as they interfere with the installation of the secure
boot monitor.

This patch also removes the above configs for the K2 GP devices, as they
are not needed, and to keep the differences between the GP and HS
defconfigs to a minimum.

4155ad9aac mmc: sdhci: fix missing cache invalidation after reading by DMA
This driver currently performs cache operation before the DMA start,
but does nothing after the DMA completion.

When reading data by DMA, the cache invalidation is needed also after
finishing the DMA transfer. Otherwise, the CPU might read data from
the cache instead of from the main memory when speculative memory read
or memory prefetch occurs.

Instead of calling the cache operation directly, this commit adds
dma_unmap_single(), which performs cache invalidation internally,
but drivers do not need which operation is being run.

58d8ace12b mmc: sdhci: use dma_map_single() instead of flush_cache() before DMA
Currently, sdhci_prepare_dma() calls flush_cache() regardless of the
DMA direction.

Actually, cache invalidation is enough when reading data from the device.

This is correctly handled by dma_map_single(), which mimics the DMA-API
in Linux kernel. Drivers can be agnostic which cache operation occurs
behind the scene.

This commit also sanitizes the difference between the virtual address
and the dma address.

fdd84c8be4 mmc: sdhci: remove unneeded casts
host->mmc is already (struct mmc *).

memalign() returns an opaque pointer, so there is no need for casting.
