7b82a229e5 sunxi: prepare for sharing MACH_SUN8I_H3 config symbol
The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores.
To allow sharing the clocks, GPIO and driver code easily, create an
architecture agnostic MACH_SUNXI_H3_H5 Kconfig symbol.
Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and
let it be selected by a new shared Kconfig option.

706865afe5 dm: core: Add flags parameter to device_remove()
This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.

9bcb018870 Revert "sf: Fix quad bit set for micron devices"
This reverts commit c56ae7519f.

Once the 'Quad Enable' bit is cleared in their Enhanced Volatile
Configuration Register (EVCR), Micron memories expect ALL commands to use
the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer
accepted.

Within the reverted commit, the write_evcr() function is implemented using
the spi_flash_write_common(), which is a shortcut for the
[ spi_flash_cmd_write_enable(), spi_flash_cmd_write(),
spi_flash_cmd_wait_ready() ] sequence.

Since the internal state of the Micron memory has been changed when the
spi_flash_cmd_write() function completes, the later call of the
spi_flash_cmd_wait_ready() function fails.

Indeed the SPI controller driver is not aware of the SPI protocol switch.

Further patches will fix the support of Micron QSPI memories.

116e005cfd sf: Remove spansion_s25fss_disable_4KB_erase
In spansion S25FS-S family the physical sectors are grouped as
normal and parameter sectors. Parameter sectors are 4kB in size
with 8 set located at the bottom or top address of a device.
Normal sectors are similar to other flash family with sizes of
64kB or 32 kB.

To erase whole flash using sector erase(D8h or DCh) won't effect
the parameter sectors, so in order to erase these we must use 4K
sector erase commands (20h or 21h) separately.

So better to erase the whole flash using 4K sector erase instead
of detecting these family parts again and do two different erase
operations.

For this:
- Removed spansion_s25fss_disable_4KB_erase code
- Add SECT_4K for S25FS512S chip

0a9b73a13e spl: spi: Move the generic SPI loader into common/spl
All the other SPL loaders are in this directory, so move the SPI one in
there too.

There are two board-specific SPI loaders (fsl and sunxi). These remain in
the drivers/mtd/spi directory, since they do not contain generic code.

ecdfd69a4b spl: Convert boot_device into a struct
At present some spl_xxx_load_image() functions take a parameter and some
don't. Of those that do, most take an integer but one takes a string.

Convert this parameter into a struct so that we can pass all functions the
same thing. This will allow us to use a common function signature.

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have

Replace all include directives for <asm/errno.h> with <linux/errno.h>.

edd35f712e sf: Simplify fastest read cmd code
Fastest read command code look for fastest read command
taking inputs from spi->mode_rx and flags from param table
and controller mode_rx is always been a priority.

Since mode_rx is always set from controller side this optimized
code doesn't require much and this code required exctra overhead like
1) Maintain e_rx_cmd in param table
2) Maintain mode_rx in spi_slave {}

Hence removed this code, and look for read command from normal
spi->mode from spi_slave{} and params->flags
