This is much more common on modern hardware, so default to using it.
This does not affect the normal UART, but does allow the debug UART to
work, since it uses serial_out_shift(), etc.

When U-Boot is the second-stage bootloader, PCI is already set up. We
cannot read the regions from the device tree. There is no point anyway,
since PCI devices have already been allocated according to the regions
and it is not safe for U-Boot to make any changes.

When coreboot does not pass a UART in its sysinfo struct, there is no
easy way to find it out.
Since coreboot does not actually init the serial device when serial is
disabled, it is not possible to make it add this information to the
sysinfo table.
Add a way to obtain this information from the DBG2 ACPI table, which is
normally set up by coreboot.
For now this only supports a memory-mapped 16550-style UART.

- Add rk3566 Anbernic boards;
- Misc fixes for drivers;
The CRU is being probed with a default set of assigned clocks, which
are not implemented in the driver at all.
Hence, when clk_set_defaults is called, it fails with ENOENT.
This would not be a problem, as the CRU still handles all the required
clocks, and the assigned clocks are default configs which are preprogrammed
or not required for Uboot operations.
However, the rockchip reset driver is being bound by the same DT node
as CRU, as the reset driver has no DT node.
But, when probing the reset node, it will call again the clk_set_defaults
for the CRU node, and failing because of missing those specific clocks
in the rk3588 clock driver.
To avoid this, simply implement a basic set/get that will just return
success and the default corresponding rate for the required assigned clocks.
As those clocks were not supported in Uboot, not required for Uboot
operations, there is no need to do any different kind of initialization.

Implement a resource release mechanism on failing probe.
Without this, a strange situation can happen e.g. when init port fails,
or attempting to get the PHY fails, because the gpios have been
requested first, and if the user tries to do 'pci enum' again, the
driver will fail with 'can't find reset gpios' even if the gpios are
there, just because they were blocked by a previous probe attempt.
It is only natural to release the acquired resources if the probe fails,
just for consistency if nothing else.
This way on subsequent probe attempts, the user will get the same error
message, and not something different that doesn't make sense.

btrfs_read_extent_reg correctly computed the extent offset in the
BTRFS_COMPRESS_NONE case, but did not account for the 'offset - key.offset'
part correctly in the compressed case, making the function read
incorrect data.
In the case I examined, the last 4k of a file was corrupted and
contained data from a few blocks prior, e.g. reading a 10k file with a
single extent:
btrfs_file_read()
-> btrfs_read_extent_reg
(aligned part loop, until 8k)
-> read_and_truncate_page
-> btrfs_read_extent_reg
(re-reads the last extent from 8k to the end,
incorrectly reading the first 2k of data)
This can be reproduced as follow:
$ truncate -s 200M btr
$ mount btr -o compress /mnt
$ pat() { dd if=/dev/zero bs=1M count=$1 iflag=count_bytes status=none | tr '\0' "\\$2"; }
$ { pat 4K 1; pat 4K 2; pat 2K 3; } > /mnt/file
$ sync
$ filefrag -v /mnt/file
File size of /mnt/file is 10240 (3 blocks of 4096 bytes)
ext: logical_offset: physical_offset: length: expected: flags:
0: 0.. 2: 3328.. 3330: 3: last,encoded,eof
$ umount /mnt
Then in u-boot:
=> load scsi 0 2000000 file
10240 bytes read in 3 ms (3.3 MiB/s)
=> md 2001ff0
02001ff0: 02020202 02020202 02020202 02020202 ................
02002000: 01010101 01010101 01010101 01010101 ................
02002010: 01010101 01010101 01010101 01010101 ................
(02002000 onwards should contain '03' pattern but went back to 01,
start of the extent)
After patch, data is read properly:
=> md 2001ff0
02001ff0: 02020202 02020202 02020202 02020202 ................
02002000: 03030303 03030303 03030303 03030303 ................
02002010: 03030303 03030303 03030303 03030303 ................
Note that the code previously (before commit e3427184f3 ("fs: btrfs:

this is a regression even if the previous code might not have been
handling offsets correctly either (something that booted now fails to

The Anbernic RGxx3 is a "pseudo-device" that encompasses the following
devices:
- Anbernic RG353M
- Anbernic RG353P
- Anbernic RG353V
- Anbernic RG353VS
- Anbernic RG503
The rk3566-anbernic-rgxx3.dtsi is synced with upstream Linux, but
rk3566-anbernic-rgxx3.dts is a U-Boot specific devicetree that
is used for all RGxx3 devices.
Via the board.c file, the bootloader automatically sets the correct
fdtfile, board, and board_name environment variables so that the
correct devicetree can be passed to Linux. It is also possible to
simply hard-code a single devicetree in the boot.scr file and use
that to load Linux as well.
The common specifications for each device are:
- Rockchip RK3566 SoC
- 2 external SDMMC slots
- 1 USB-C host port, 1 USB-C peripheral port
- 1 mini-HDMI output
- MIPI-DSI based display panel
- ADC controlled joysticks with a GPIO mux
- GPIO buttons
- A PWM controlled vibrator
- An ADC controlled button
All of the common features are defined in the devicetree synced from
upstream Linux.

Some RK3399 boards, such as newer revisions of NanoPi R4S, do not
provide an EEPROM chip containing a globally unique MAC address.
Currently, this means that a randomly generated temporary MAC address
may be generated each time the device is rebooted, leading to ARP cache
issues and other confusing bugs.
Since RK3399 CPUs provide a built-in unique serial number, we can
reliably derive a locally MAC address from it by reading the
corresponding bits from the non-secure efuse block.
Enable configuration options that allow deriving a local MAC address
from the CPU serial number.
The DT specification supports CPUs with both 32-bit and 64-bit addressing
capabilities. In U-boot the fdt_addr_t and phys_addr_t size are coupled
by a typedef. The MTD NAND drivers for 32-bit CPU's can describe partitions
with a 64-bit reg property. These partitions synced from Linux end up with
the wrong offset and sizes when only the lower 32-bit is passed.
Decouple the fdt_addr_t and phys_addr_t size as they don't necessary
