env: make file-scope env_ptr variables static
The combination ENV_IS_IN_NVRAM=y, ENV_IS_IN_REMOTE=y fails to build:

env/nvram.o:/mnt/ext4/devel/u-boot/env/nvram.c:41: first defined here
It's not necessarily a meaningful combination, but for build-testing
it's nice to be able to enable most ENV_IS_IN_* at the same time, and
since these env_ptr are not declared anywhere, they really have no
reason to have external linkage.

decompress_lzo: header error, in_len=
88539136 clen=65534 tot_len=62580
NOTE: except the last line, all other lines are debug output.
Btrfs lzo compression uses its own format to record compressed size
(segment header, LE32).
However to make decompression easier, we never put such segment header
across page boundary.
In above case, the xxd dump of the lzo compressed data looks like this:
00001fe0: 4cdc 02fc 0bfd 02c0 dc02 0d13 0100 0001 L...............
00001ff0: 0000 0008 0300 0000 0000 0011 0000|0000 ................
00002000: 4705 0000 0001 cc02 0000 0000 0000 1e01 G...............
'|' is the "expected" segment header start position.
But in that page, there are only 2 bytes left, can't contain the 4 bytes
segment header.
So btrfs compression will skip that 2 bytes, put the segment header in
next page directly.
Uboot doesn't have such check, and read the header with 2 bytes offset,
result 0x05470000 (
88539136), other than the expected result
0x00000547 (1351), resulting above error.
Follow the btrfs-progs restore implementation, by introducing tot_in to
record total processed bytes (including headers), and do proper page
boundary skip to fix it.
Please note that, current code base doesn't parse fs_info thus we can't
grab sector size easily, so it uses PAGE_SIZE, and relying on fs open
time check to exclude unsupported sector size.

fs: btrfs: Reject fs with sector size other than PAGE_SIZE
Although in theory u-boot fs driver could easily support more sector
sizes, current code base doesn't have good enough way to grab sector
size yet.
This would cause problem for later LZO fixes which rely on sector size.
And considering that most u-boot boards are using 4K page size, which is
also the most common sector size for btrfs, rejecting fs with
non-page-sized sector size shouldn't cause much problem.
This should only be a quick fix before we implement better sector size

sandbox: also restore terminal settings when killed by SIGINT
Hitting Ctrl-C is a documented way to exit the sandbox, but it is not
actually equivalent to the reset command. The latter, since it follows
normal process exit, takes care to reset terminal settings and
restoring the O_NONBLOCK behaviour of stdin (and, in a terminal, that
is usually the same file description as stdout and stderr, i.e. some
/dev/pts/NN).
Failure to restore (remove) O_NONBLOCK from stdout/stderr can cause
very surprising and hard to debug problems back in the terminal. For
example, I had "make -j8" consistently failing without much
information about just exactly what went wrong, but sometimes I did
get a "echo: write error". I was at first afraid my disk was getting
bad, but then a simple "dmesg" _also_ failed with write error - so it
was writing to the terminal that was buggered. And both "make -j8" and
dmesg in another terminal window worked just fine.
So install a SIGINT handler so that if the chosen terminal
mode (cooked or raw-with-sigs) means Ctrl-C sends a SIGINT, we will
still call os_fd_restore(), then reraise the signal and die as usual
from SIGINT.

With P2SB the initial BAR (base-address register) is set up by TPL and
this is used unchanged right through U-Boot.
At present the reading of this address is split between the ofdata() and
probe() methods. There are a few problems that are unique to the p2sb.
One is that its children need to call pcr_read32(), etc. which needs to
have the p2sb address correct. Also some of its children are pinctrl
devices and pinctrl is used when any device is probed. So p2sb really
needs to get its base address set up in ofdata_to_platdata(), before it is
probed.
Another point is that reading the p2sb BAR will not work if the p2sb is
hidden. The FSP-S seems to hide it, presumably to avoid confusing PCI
enumeration.
Reading ofdata in ofdata_to_platdata() is the correct place anyway, so
this is easy to fix.
Move the code into one place and use the early-regs property in all cases
for simplicity and to avoid needing to probe any PCI devices just to read
the BAR.

tpm: cr50: Release locality on exit
At present the cr50 driver claims the locality and does not release it for
Linux. This causes problems. Fix this by tracking what is claimed, and
adding a 'remove' method.

cpu: Support querying the address width
Different CPUs may support different address widths, meaning the amount of
memory they can address. Add a property for this to the cpu_info struct.

x86: acpi: Let OS know that console already had been initialized
SPCR has no clue if the UART base clock speed is different to
the default one. However, the SPCR 1.04 defines baud rate 0 as
a preconfigured state of UART and OS is supposed not to touch
the configuration of the serial device.
Linux kernel supports that starting from v5.0, see commit
b413b1abeb21 ("ACPI: SPCR: Consider baud rate 0 as preconfigured state")
for the details.

dm: serial: Add clock member to struct serial_device_info
Some callers of serial_getinfo() would like to know the UART base
clock speed in order to make decision what to pass to OS in some
cases. In particular, ACPI SPCR table expects only certain base
clock speed and thus we have to act accordingly.
