FIT images don't work without having to explicitly specify physical
load addresses. Digging into that it looks like a flaw in
bootm_load_os().
It duplicates images->os for convenience. However, the code handling
"kernel_noload" images then updates the load address in the copy with
the value lmb_alloc_mem() returned. Later there's another call to
lmb_alloc_mem() that uses the old value. This leads to havoc due
to subsequent calls of lmb_alloc_mem() picking too low addresses.
The "fix" is to mark the local variable const to avoid accidental
assignments. This works but IMO the logic is still flawed somehow as
this leads to overlapping lmb reservations. I guess the fixed
reservation should only be done when the noload path wasn't hit.

As explained in commit 03d2d5fc003f ("board: sifive: unmatched: set
fdtfile with unquoted variable.") using the syntax of
'fdtfile=CONFIG_DEFAULT_FDT_FILE' in the plain text environment files

This small series consolidate header usage of mdio-mt7531-mmio driver
and improve usage in preparation for support of OF PHY autoprobe.
This driver is still not used (as it will be used by AN7581/AN7583)
in the OF mode (it's used by MT7988 for the MDIO functions)
For OF PHY to be correctly autoprobed, the MDIO driver needs to attached
to the MDIO node (the parent of the PHY nodes)
With such change the MDIO driver can be binded with the MDIO node instead
of the switch node as previously required.

The MDIO node is ALWAYS a parent of the MT7531 switch node and the MDIO
registers are in the MT7531 register space (in the context of MT7988
it's all memory-mapped)
With these assumption, we can simplify and permit better usage of PHY OF
automatic probing by binding the mt7531-mdio-mmio driver with the MDIO
node instead of the switch node.
For OF PHY to be correctly autoprobed, the MDIO driver needs to attached
to the MDIO node (the parent of the PHY nodes).
The driver will reach the parent node (the switch node) and will parse
the register address from there.

sqfs_frag_lookup() reads a 16-bit metadata block header whose lower
15 bits encode the data size. Unlike sqfs_read_metablock() in
sqfs_inode.c, this function does not validate that the decoded size is
within SQFS_METADATA_BLOCK_SIZE (8192). A malformed SquashFS image can
set the size field to any value up to 32767, causing memcpy to write
past the 8192-byte 'entries' heap buffer.
Add the same bounds check used by sqfs_read_metablock(): reject any
metadata block header with SQFS_METADATA_SIZE(header) exceeding
SQFS_METADATA_BLOCK_SIZE.

Currently when CONFIG_SPL_STACK_R and CONFIG_SPL_SYS_MALLOC_SIMPLE is
enabled then spl_relocate_stack_gd() will setup a layout where the stack
lays inside the heap and grows down to heap start. Also the global data
is part of the heap. This can lead to corruption of stack and global
data. The current layout is:
0x0 +-------------+
. .
. .
gd->malloc_base +- - - - - - -+
| |\
| HEAP/STACK | \
| | } SPL_STACK_R_MALLOC_SIMPLE_LEN
gd->start_addr_sp +- - - - - - -+ / (gd->malloc_limit)
| GLOBAL DATA |/
CONFIG_SPL_STACK_R_ADDR +-------------+
The above broken layout was actually introduced with commit adc421e4cee8
("arm: move gd handling outside of C code").
This commit changes the layout so that the stack is below the heap and
the global data. It is now similar to the one before relocation:

We currently provide default board names for each board in their

overwrites the default DT as set in the defconfig

This patch changes the default name to be NULL which prevents this

single-word support"
Niko Mauno <niko.mauno@vaisala.com> says:
In this series, we first introduce a clean-up where we switch to use
predefined bit masks instead of hard-coded values for count and magic
halves in the single-word (32-bit) boot count scheme.
Then we fix a case of missing boot count value masking in single-word
scenario in bootcount.c, which allowed clobbering of the magic half
when storing the value. With this change the clobbering preventing
behavior becomes consistent with existing single word bootcount storing
implementations in bootcount_at91.c and bootcount_davinci.c.
Finally, we enable the DM I2C bootcount driver to work also in single
word (4 byte) mode, in addition to the pre-existing half-word (2 byte)
mode. By default the driver still operates in half word mode as so far,
but can now be used alternatively in single word mode by adding
'size = <0x4>;' in the associated device tree node.

Add simple test for zip/unzip/gzwrite commands. The test works as
follows. First, create three buffers with a bit of space between
each of them, fill them with random data, then compress data in
buffer 1 into buffer 2, decompress data in buffer 2 either directly
into buffer 3 or into MMC 1 and then read them back into buffer 3,
and finally compare buffer 1 and buffer 3, they have to be identical.
The buffers are filled with random data to detect out of bounds writes.
Test for various sizes, both small and large and unaligned.
The test uses ut_assert_skip_to_line() to skip over gzwrite progress
bar. Since the progress bar updates fill up the console record buffer,
increase the size of it to compensate.
