fs/btrfs: fix a bug that U-boot fs btrfs implementation doesn't handle NO_HOLE feature correctly

[BUG]
When passing a btrfs with NO_HOLE feature to U-boot, and if one file
contains holes, then the hash of the file is not correct in U-boot:

 # mkfs.btrfs -f test.img # Since v5.15, mkfs defaults to NO_HOLES
 # mount test.img /mnt/btrfs
 # xfs_io -f -c "pwrite 0 4k" -c "pwrite 8k 4k" /mnt/btrfs/file
 # md5sum /mnt/btrfs/file
 277f3840b275c74d01e979ea9d75ac19  /mnt/btrfs/file
 # umount /mnt/btrfs
 # ./u-boot
 => host bind 0 /home/adam/test.img
 => ls host 0
 <   >      12288  Mon Dec 27 05:35:23 2021  file
 => load host 0 0x1000000 file
 12288 bytes read in 0 ms
 => md5sum 0x1000000 0x3000
 md5 for 01000000 ... 01002fff ==> 855ffdbe4d0ccc5acab92e1b5330e4c1

The md5sum doesn't match at all.

[CAUSE]
In U-boot btrfs implementation, the function btrfs_read_file() has the
following iteration for file extent iteration:

/* Read the aligned part */
while (cur < aligned_end) {
ret = lookup_data_extent(root, &path, ino, cur, &next_offset);
if (ret < 0)
goto out;
if (ret > 0) {
/* No next, direct exit */
if (!next_offset) {
ret = 0;
goto out;
}
}
/* Read file extent */

But for NO_HOLES features, hole extents will not have any extent item
for it.
Thus if @cur is at a hole, lookup_data_extent() will just return >0, and
update @next_offset.

But we still believe there is some data to read for @cur for ret > 0
case, causing we read extent data from the next file extent.

This means, what we do for above NO_HOLES btrfs is:
- Read 4K data from disk to file offset [0, 4K)
  So far the data is still correct

- Read 4K data from disk to file offset [4K, 8K)
  We didn't skip the 4K hole, but read the data at file offset [8K, 12K)
  into file offset [4K, 8K).

  This causes the checksum mismatch.

[FIX]
Add extra check to skip to the next non-hole range after
lookup_data_extent().

nand: gpmc: Handle bitflips in erased pages when using BCH ECC engine

In the case of an erased (sub)page both the data and ECC are all 0xFF
bytes. This fails the normal ECC verification, as the computed ECC of
all-0xFF is not also 0xFF. The GPMC NAND driver attempted to detect
erased pages by checking that the ECC bytes are all-0xFF, but this had
two problems:
1) bitflips in the data were not corrected, so the data looked not-erased
2) bitflips in the ECC bytes were reported as uncorrectable ECC errors

The equivalent Linux driver [1] correctly handles this by counting the
number of 0-bits in the combination of data and ECC bytes. If the number
of 0-bits is less than the amount of bits correctable by the selected
ECC algorithm, then it is treated as an erased page with correctable
bitflips.

whether or not to apply a dtbo depending on the hardware configuration.
e.g: for TI's AM335x EVM, it would be convenient to apply a particular

This change can be used for different use-cases and bring more
flexibilty to consumers who use sysboot/pxe_utils.

if "pxe_label_override" is set but does not exist in the pxe menu,

efi_loader: Get rid of kaslr-seed if EFI_RNG_PROTOCOL is installed

U-Boot, in some occasions, injects a 'kaslr-seed' property on the /chosen
node. That would be problematic in case we want to measure the DTB we
install in the configuration table, since it would change across reboots.

The Linux kernel EFI-stub completely ignores it and only relies on
EFI_RNG_PROTOCOL for it's own randomness needs (i.e the randomization
of the physical placement of the kernel). In fact it (blindly) overwrites
the existing seed if the protocol is installed. However it still uses it
for randomizing it's virtual placement.
So let's get rid of it in the presence of the RNG protocol.

It's worth noting that TPMs also provide an RNG.  So if we tweak our
EFI_RNG_PROTOCOL slightly and install the protocol when a TPM device
is present the 'kaslr-seed' property will always be removed, allowing
us to reliably measure our DTB.

phy: Track power-on and init counts in uclass

On boards using the RK3399 SoC, the USB OHCI and EHCI controllers share
the same PHY device instance. While these controllers are being stopped
they both attempt to power-off and deinitialize it, but trying to
power-off the deinitialized PHY device results in a hang. This usually
happens just before booting an OS, and can be explicitly triggered by
running "usb start; usb stop" in the U-Boot shell.

Implement a uclass-wide counting mechanism for PHY initialization and
power state change requests, so that we don't power-off/deinitialize a
PHY instance until all of its users want it done. The Allwinner A10 USB
PHY driver does this counting in-driver, remove those parts in favour of
this in-uclass implementation.

The sandbox PHY operations test needs some changes since the uclass will
no longer call into the drivers for actions matching its tracked state
(e.g. powering-off a powered-off PHY). Update that test, and add a new
one which simulates multiple users of a single PHY.

The major complication here is that PHY handles aren't deduplicated per
instance, so the obvious idea of putting the counts in the PHY handles
don't immediately work. It seems possible to bind a child udevice per
PHY instance to the PHY provider and deduplicate the handles in each
child's uclass-private areas, like in the CLK framework. An alternative
approach could be to use those bound child udevices themselves as the
PHY handles. Instead, to avoid the architectural changes those would
require, this patch solves things by dynamically allocating a list of
structs (one per instance) in the provider's uclass-private area.

  Resetting CPU ...

This happens when nvme_print_info() tries to return to the caller. It
looks like this error is caused by trying to allocate 8 KiB of memory
on the stack by the two uses of ALLOC_CACHE_ALIGN_BUFFER().

Use malloc_cache_aligned() to allocate this memory dynamically instead.

This fixes 'nvme detail' on Turris Omnia.

Note that similar change was applied to file drivers/nvme/nvme.c in past by
commit 2f83481dff9c ("nvme: use page-aligned buffer for identify command").
