spl: Convert SYS_MMCSD_RAW_MODE_KERNEL_SECTOR to Kconfig
Falcon mode is very useful in improving boot speed. A question that
Falcon mode asks is "Where do I look for the kernel". With MMC boot
media, the correct answer is CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR.
The scope of this patch is to move this to Kconfig.
It is possible for a system to support Falcon mode from NOR but not
MMC. In that case, mmc_load_image_raw_os() would not be used. To
address this, conditionally compile mmc_load_image_raw_os() when
SPL_FALCON_BOOT_MMCSD, instead of SPL_OS_BOOT.

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

# 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().

Fix wrong QSPI clock calculation for AM4372
On AM4372 the SPI_GCLK input gets its clock from the PRCM module which
divides the PER_CLKOUTM2 frequency (192MHz) by a fixed factor of 4.
See AM437x Reference Manual in section 27 QSPI >> 27.2 Integration.
The QSPI_FCLK therefore needs to take this factor into account and
becomes (192000000 / 4).

The fastboot protocol uses per default the UDP port 5554. In some cases
it might be needed to change the used port. The fastboot utility provides
a way to specifiy an other port number to use already.

net: fsl: Fix busy flag polling register
NXP's mEMAC reference manual, Chapter 6.5.5 "MDIO Ethernet Management
Interface usage", specifies to poll the BSY (0) bit in the CFG/STAT
register to wait until a transaction has finished, not bit 31 in the
data register.
In the Linux kernel, this has already been fixed in commit 26eee0210ad7
("net/fsl: fix a bug in xgmac_mdio").
This patch changes the register in the fman_mdio and fsl_ls_mdio
drivers.
As the MDIO_DATA_BSY define is no longer in use, this patch also removes
its definition from the fsl_memac header.

net: dsa: sja1105: fix device id detection
The sja1105_check_device_id() function contains logic to work without
changing the device tree on reworked boards, one of which I have (the
NXP LS1021A-TSN normally has a SJA1105T, but I have a version with a
resoldered SJA1105Q which is pin compatible). This logic is taken from
the Linux driver.
However this logic gets shortcircuited in U-Boot by an earlier check for
the exact device ID specified in the device tree. So the reworked board
does not probe the SJA1105Q switch. Remove this duplicated logic and let
the automatic device ID detection do its job.

net: dsa: fix phydev->speed being uninitialized for the CPU port fixed PHY
If the DSA API is going to allow drivers to do things such as:
- phy_config in dsa_ops :: port_probe
- phy_startup in dsa_ops :: port_enable
then it would actually be good if the ->port_probe() method would
actually be called in all cases before the ->port_enable() is.
Currently this is true for user ports, but not true for the CPU port,
because the CPU port does not have a udevice registered for it (this is
all part of DSA's design). So the current issue is that after
phy_startup has finished for the CPU port, its phydev->speed is an
uninitialized value, because phy_config() was never called for the
priv->cpu_port_fixed_phy, and it is precisely phy_config() who copies
the speed into the phydev in the case of the fixed PHY driver.
So we need to simulate a probing event for the CPU port by manually
calling the driver's ->port_probe() method for the CPU port.

cmd: pxe_utils: sysboot: add label override support
This will allow consumers to choose a pxe label at runtime instead of
having to prompt the user. One good use-case for this, is choosing
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
dtbo only when the J9 jumper is on PRUSS mode. To achieve this, the
pxe menu should have 2 labels, one with the dtbo and the other without,
then the "pxe_label_override" env variable should point to the label with
the dtbo at runtime only when the jumper is on PRUSS mode.
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,
the code should fallback to the default label if given, and no failure
is returned but rather a warning message.
