8699af63b8 lib/crypto: Enable more algorithms in cert verification
Right now the code explicitly limits us to sha1,256 hashes with RSA2048
encryption.  But the limitation is artificial since U-Boot supports
a wider range of algorithms.

The internal image_get_[checksum|crypto]_algo() functions expect an
argument in the format of <checksum>,<crypto>.  So let's remove the size
checking and create the needed string on the fly in order to support
more hash/signing combinations.

0487238120 lib: printf code %pUs for GUID text representation
In different places text representations are used for GUIDs, e.g.

* command efidebug
* command part list for GPT partitions

To allow reducing code duplication introduce a new printf code %pUs.
It will call uuid_guid_get_str() to get a text representation. If none is
found it will fallback to %pUl and print a hexadecimal representation.

7c075433fe 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().

These are different i2c busses even if the node is the same, and have to be

Without this config, the sequence number 0 is reused for two i2c busses, and
this is something that we have to avoid:

c918e2c303 arm: dts: apple: Update Apple M1 device trees
This synchronizes the device trees with those that are in the
process of being upstreamed into Linux. This is mostly the
current state of the device trees on the asahilinux branch
with a few extra bits used by OpenBSD. This includes device
trees for machines that were still missing.

There are still some differences that will hopefully be resolved
soon.

609983e981 board: ti: am335x: Choose CPSW or PRUSS configuration based on jumper setting
The am335x-ice-v2 board's Ethernet ports can be configured
in 'MII' or 'RMII' mode to be connected to 'PRUSS' or 'CPSW'
Ethernet subsystems.

This patch sets the environment variable 'ice_mii' to
'mii' or 'rmii' accordingly. Based on that we choose the
appropriate board devicetree i.e. 'am335x-ice-v2.dtb' or
'am335x-ice-v2-prueth.dtb'.

Since there are 2 Ethernet ports with 2 modes, there can be 4
configurations but for now we consider both ports in different modes
to be an invalid configuration and prevent boot in that case.

f44bcb9f0d 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.

Implement similar, though simplified, logic in omap_correct_data_bch().

[1] see omap_elm_correct_data() in omap2.c
