Buswidth is depeneded on Hardware schematic.
Evne though host can support the 8bit buswidth, if hardware doesn't
support 8bit mode, it doesn't work fine.
So the buswidth mode selection leaves a matter in each SoC drivers.
On the contrary to this, hardware supports 8bit mode, but host doesn't
support it. then controller has to disable the MMC_MODE_8BIT.
(Host can check whether 8bit mode is supported or not, since V3.0)

Without this patch if scsi reset or scan is called new block devices are
created which point to the same id and lun.

Now that the SPL is ready to be compiled in AArch64 and the DRAM
init code is ready, enable SPL support for the A64 SoC and in the
Pine64 defconfig.
For now we keep the boot0 header in the U-Boot proper, as this allows
to still use boot0 as an SPL replacement without hurting the SPL use
case.
We disable FEL support for now by making its compilation conditional
and disabling it for ARM64, as the code isn't ready yet.

The A64 DRAM controller is very similar to the H3 one,
so the code can be reused with some small changes.

So far the DRAM driver for the H3 SoC (and apparently boot0/libdram as
well) only applied coarse delay line settings, with one delay value for
all the data lines in each byte lane and one value for the control lines.
Instead of setting the delays for whole bytes only allow setting it for
each individual bit. Also add support for address/command lane delays.
For the purpose of this patch the rules for the existing coarse settings
were just applied to the new scheme, so the actual register writes don't
change for the H3. Other SoCs will utilize this feature later properly.
With a stock GCC 5.3.0 this increases the dram_sun8i_h3.o code size from
2296 to 2344 Bytes.

So far the MBUS priority setup was done by writing "magic" values taken
from a DRAM controller register dump after a boot0 run.
By peeking at the Linux (sic!) MBUS driver [1] from the Allwinner BSP
kernel, we learned more about the actual meaning of those bits.
Add macros and refactor the setup function to make the MBUS setup much
more readable and meaningful.
The actual values used now are a transformation of the values used
before, which are assembled by the new code to result in the same register
writes. So this rework does not change any settings, also the code size
stays the same.
The respective source files in the BSP kernel had a proper GPL header,
so lifting this code and information into U-Boot is legal.

The Allwinner A64 SoC starts execution in AArch32 mode, and both
the boot ROM and Allwinner's boot0 keep running in this mode.
So U-Boot gets entered in 32-bit, although we want it to run in AArch64.
By using a "magic" instruction, which happens to be an almost-NOP in
AArch64 and a branch in AArch32, we differentiate between being
entered in 64-bit or 32-bit mode.
If in 64-bit mode, we proceed with the branch to reset, but in 32-bit
mode we trigger an RMR write to bring the core into AArch64/EL3 and
re-enter U-Boot at CONFIG_SYS_TEXT_BASE.
This allows a 64-bit U-Boot to be both entered in 32 and 64-bit mode,
so we can use the same start code for the SPL and the U-Boot proper.
We use the existing custom header (boot0.h) functionality, but restrict
the existing boot0 header reservation to the non-SPL build now. A SPL
wouldn't need such header anyway. This allows to have both options
defined and lets us use one for the SPL and the other for U-Boot proper.
Also add arch/arm/mach-sunxi/rmr_switch.S, which contains the original
ARM assembly code and instructions how to re-generate the encoded
version.

For prepending some board specific header area to U-Boot images we
were so far including a header file with a macro definition containing
the actual header specification.
This works fine if there are just a few statements and if there is only
one alternative.
However adding more complex code quickly gets messy with this approach,
so let's just drop that intermediate macro and let the #include actually
insert the code directly.
This converts the callers and the callees, but doesn't change anything
at this point.

The boot0 hook we have so far is applied _after_ the initial branch
to the "reset" entry point. An upcoming change requires even this
branch to be changed, so we apply the hook macro at the earliest
point, and have the branch in the hook file as well.
This is no functional change at this point, just refactoring to simplify
upcoming patches.

tiny-printf does not know about the "l" modifier so far, which breaks
the crash dump on AArch64, because it uses %lx to print the registers.
Add an easy way of handling longs correctly.
Using a relatively decent compiler (GCC 5.3.0) this does _not_ increase
the code size of tiny-printf.o for 32-bit builds (where long and int
are actually the same), actually it looses three (ARM Thumb2) instructions
from the actual SPL (numbers for orangepi_plus_defconfig):
text data bss dec hex filename
758 0 0 758 2f6 spl/lib/tiny-printf.o before
18839 488 232 19559 4c67 spl/u-boot-spl before
758 0 0 758 2f6 spl/lib/tiny-printf.o after
18833 488 232 19553 4c61 spl/u-boot-spl after
This adds some substantial amount of code to a 64-bit build, though:

The predominantely 32-bit ARM targets try to compile the SPL in Thumb
mode to reduce code size.
The 64-bit AArch64 instruction set does not know an alternative, concise
encoding, so the Thumb build option should only be set for 32-bit
targets.
Likewise -marm machine options are only valid for ARMv7 targets.

These days many Allwinner SoCs use clock_sun6i.c, although out of them
only the (original sun6i) A31 has a second MBUS clock register.
Also the requirement for setting up the PRCM PLL_CTLR1 register to provide
the proper voltage seems to be a property of older SoCs only as well.
Restrict the MBUS initialization to this SoC only to avoid writing bogus
values to (undefined) registers in other chips.
I can only verify that the PLL voltage setup is not needed for H3 and
A64, so for now we only spare those two SoCs.

When TI_SECURE_DEV_PKG is not defined we warn that the file '*_HS' was
not generated but generate an unsigned one anyway, first fix this
warning to say that it was generated but not secured.
When the user then exports TI_SECURE_DEV_PKG after getting this warning,
and tries to re-build, 'make' will detect the build artifacts as
unchanged and so assume they do not need to be re-generated. This causes
it to fail to sign the files and it will pack unsigned files into the
final image, even though TI_SECURE_DEV_PKG is now correctly defined and
working.
Fix this by using FORCE on the targets causes them to be re-run even if
the dependent files have not changed.
This then causes another issue. We currently rename the signed dtb files
to overwrite the non-signed ones. We do this so the 'mkimage' tool gives
the packaged dtb sections the correct name. If we do not rename the files
then SPL will not find them during boot.
Fix this by renaming the dtb files by appending _HS to the end of the
filename, after the ".dtb", this causes them to still be named correctly
in the FIT blob.

Fix ULPI reset polarity which caused a hard hang on Colibri T20 upon
attempting to start the USB subsystem:
This fixes my late commit d5a24d8b53d350364bd429b7104ec369b817e4b8
(colibri_t20: fix usb operation and controller order) inadvertently
having overwritten Stephen's previous commit
2f6a7e8ce5df8b99d84bfd486c6f99d92322ce04 (ARM: tegra: fix USB ULPI PHY
reset signal inversion confusion).
While at it also fix comment about on-module USB port.
