Cypress defines two flavors of configuration registers, volatile and
non volatile, and both use the same bit fields. Rename the bitfields in
the configuration registers so that they can be used for both flavors.

This contains some fixes, and the first bunch of some clean up patches
to get rid of legacy GPIO and PMIC code.
Highlight is the DM AXP PMIC driver, which is required to convert some
drivers over to use DM regulators, and also is required to get rid
of some less optimal PMIC setup code in Trusted Firmware. This isn't
enabled by any defconfig yet, but can be enabled manually and works. For
the full glory some patches are still missing, and this requires more
testing, which would be simpler if the core code is upstream.
Drop the use of scripts and rely on standard boot for all operation.

At present we set up the bootdev order at the start, then scan the
bootdevs one by one.
However this approach cannot be used with hunters, since the bootdevs may
not exist until the hunter is used. Nor can we just run all the hunters at
the start, since that violate's U-Boot's 'lazy init' requirement. It also
increases boot time.
So we need to adjust the algorithm to scan by labels instead. As a first
step, drop the dev_order[] array in favour of a list of labels. Update the
name of bootdev_setup_iter_order() to better reflect what it does.

bit annoying. The only real reason for it is to have a name like
'mmc0.bootdev' instead of 'mmc0.blk.bootdev'.

When using the USB OTG FEL mode on the Allwinner H616, the BootROM
stores some data at the end of SRAM C. This is also the location where
we place the initial SPL stack, so it will overwrite this data.
We still need the BROM code after running the SPL, so should leave that
area alone.
Interestingly this does not seem to have an adverse effect, I guess on
the "way out" (when we return to FEL after the SPL has run), this data
is not needed by the BROM, for just the trailing end of the USB operation.
However this is still wrong, and we should not clobber BROM data.
Lower the SPL stack address to be situated right below the swap buffers
we use in sunxi-fel: that should be out of the way of everyone else.

Prior to commit 9591b63531 ("Convert CONFIG_SYS_NS16550_MEM32 et al to

DM_SERIAL such that we would then have a size 0 character array. This
resulted in functionally no padding. The confusion on my part came from
dealing with the constraints around platforms that do not use DM_SERIAL
in SPL/TPL. After Andre Przywara reported that sunxi was broken, I've
re-read the code and comments again and thought on this harder. What we
want I believe is what this patch does now.
If DM_SERIAL is defined for this stage, regardless of
CONFIG_SYS_NS16550_REG_SIZE then we will dynamically handle reg shifts
and 'struct ns16550' needs no padding (which is functionally what
unsigned char foo[0] provides). This is the same case as NS16550_DYNAMIC
and DEBUG_UART. Expand the existing comment here slightly.
Otherwise, we will have CONFIG_SYS_NS16550_REG_SIZE set to a non-zero
value, and handle padding within the struct.

use when relocating images, and not otherwise constrained, was changed
to include all known memory banks. In the case of this platform however,
all of the memory known to U-Boot is not also part of the Linux kernel
"lowmem" and so we must use CFG_SYS_BOOTMAPSZ to limit where we relocate
images to. We set a conservative limit of 256MB here to mirror the

Update the zstd implementation to match Linux zstd 1.5.2 from commit
2aa14b1ab2.
This was motivated by running into decompression corruption issues when
trying to uncompress files compressed with newer versions of zstd. zstd
users also claim significantly improved decompression times with newer
zstd versions which is a side benefit.
Original zstd code was copied from Linux commit 2aa14b1ab2 which is a
custom-built implementation based on zstd 1.3.1. Linux switched to an
implementation that is a copy of the upstream zstd code in Linux commit
e0c1b49f5b, this results in a large code diff. However this should make
future updates easier along with other benefits[1].
This commit is a straight mirror of the Linux zstd code, except to:
- update a few #include that do not translate cleanly
- linux/swab.h -> asm/byteorder.h
- linux/limits.h -> linux/kernel.h
- linux/module.h -> linux/compat.h
- remove assert() from debug.h so it doesn't conflict with u-boot's
assert()
- strip out the compressor code as was done in the previous u-boot zstd
- update existing zstd users to the new Linux zstd API
- change the #define for MEM_STATIC to use INLINE_KEYWORD for codesize
- add a new KConfig option that sets zstd build options to minify code
based on zstd's ZSTD_LIB_MINIFY[2].
These changes were tested by booting a zstd 1.5.2 compressed kernel inside a
FIT. And the squashfs changes by loading a file from zstd compressed squashfs
with sqfsload. buildman was used to compile test other boards and check for
binary bloat, as follows:
> $ buildman -b zstd2 --boards dh_imx6,m53menlo,mvebu_espressobin-88f3720,sandbox,sandbox64,stm32mp15_dhcom_basic,stm32mp15_dhcor_basic,turris_mox,turris_omnia -sS

To quote the author:
So far standard boot lacks a boot menu, although it is possible to create
a rudimentary one using the existing 'bootmenu' command.
Even then, this text-based menu offer only basic functionality and does
not take full advantage of the displays which are common on many devices.
This series provides a 'bootflow menu' command which allows the user to
select from the available bootflows. An attempt is made to show the name
of the available operating systems, by reading more information into the
bootflow. A logo can be read also, where supported, so that this can be
presented to the user when an option is highlighted.
Full use is made of TrueType fonts, if enabled. For cases where only a
serial console is available, it falls back to a simple text-based menu.
All of this is implementing using a new 'expo' construct, a collection of
scenes (like menu screens) which can be navigated by the user to view
information and select options. This is fairly general and should be able
to cope with a wider array of use cases, with less hacking of the menu
code, such as is currently needed for CMD_BOOTEFI_BOOTMGR.
Of course it would be possible to enhance the existing menu rather than
creating a new setup. Instead it seems better to make the existing menu
use expo, if code space permits. It avoids the event-loop problem and
should be more extensible, given its loosely coupled components and use of
IDs instead of pointers. Further motivation is provided in the
documentation.
For now the CLI keypress-decoding code is split out to be used by the new
menu. The key codes defined by menu.h are reused also.
This is of course just a starting point. Some ideas for future work are
included in the documentation.
