The existing memory layout places the bloblist at 0xb000 and the fdt at
0x100, resulting in a 0xaf00 size constraint for the fdt. This constraint
has been reached. Lets modify the layout by moving the bloblist to 0x100,
device tree to 0x1000 and placing early memory allocation after pre-console
buffer at 0xf4000. This should guarantee sufficient memory allocation for
future expansion.

This series adds support for file renaming to EFI_FILE_PROTOCOL.SetInfo().
One of the use cases for renaming in EFI is to facilitate boot loader
boot counting.
No existing filesystems in U-Boot currently include file renaming,
resulting in support for renaming at the filesystem level and a
concrete implementation for the FAT filesystem.

POSIX filesystem functions that create or remove directory entries contain
text along the lines of "[function] shall mark for update the last data
modification and last file status change timestamps of the parent
directory of each file." [1][2][3] The common theme is these timestamp
updates occur when a directory entry is added or removed. The
create_link() and delete_dentry_link() functions have been changed to
update the modification timestamp on the directory where the direntry
change occurs. This differs slightly from Linux in the case of rename(),
where Linux will not update `new_path`'s parent directory's timestamp if
it is replacing an existing file. (via `vfat_add_entry` [4])
The timestamps are not updated if the build configuration does not support
RTCs. This is an effort to minimize introducing erratic timestamps where
they would go from [current date] -> 2000-01-01 (error timestamp in the
FAT driver). I would assume an unchanged timestamp would be more valuable
than a default timestamp in these cases.

The implementation roughly follows the POSIX specification for
rename() [1]. The ordering of operations attempting to minimize the chance
for data loss in unexpected circumstances.
The 'mv' command was implemented as a front end for the rename operation
as that is what most users are likely familiar with in terms of behavior.
The 'FAT_RENAME' Kconfig option was added to prevent code size increase on
size-oriented builds like SPL.

A problem we have today is that some instances of IS_ENABLED(FOO) have
crept in to the code. This is in turn because with checkpatch.pl this is
only a warning and not an error, so they were overlooked. And looking
deeper, in the Linux kernel this pattern is allowed because
IS_ENABLED(DEFINED_FLAG) is allowed if discouraged and a quick skim of
the instances I saw in the current kernel follow this pattern. In U-Boot
however, this is not allowed, so bump to an error.

With a recent Binman change, the skip-at-start property is now honoured,
meaning that all image-pos values in the affected section start from

The x86 code works around the old behaviour at present, so update it.
Signed-off-by: Simon Glass <sjg@chromium.org>
A discussion on the mailing list about dealing with block offsets and
binman symbols made me think that something is wrong with how Binman
deals with the skip-at-start property.
The feature was originally designed to handle x86 ROMs, which are mapped
at the top of the address space. That seemed too specific, whereas
skipping some space at the start seemed more generally useful.
It has proved useful. For example, rockchip images start at block 64,
so a skip-at-start of 0x8000 deals with this.
But it doesn't actually work correctly, since the image_pos value does
not give the actual position on the media.
Fix this and update the documentation, moving it into the 'section'
section.

The commit bc07851897 ("board: ti: Pull redundant DDR functions to a
common location and Fixup DDR size when ECC is enabled") broke DRAM
support for the Verdin AM62. This was partially fixed with commit
3f866c47b5 ("board: verdin-am62: add dram_init_banksize"). However,
because fixup_memory_node was not called, the Linux kernel was started
with the wrong memory size on modules with less memory available. This
resulted in boot failures. Fix this issue by calling fixup_memory_node
in the board file.
spl_perform_fixups will be called in the SPL and now sets the correct
memory size in the device tree of U-Boot by calling fixup_memory_node.
U-Boot will then adjust the memory sizes of Linux during bootm/booti in
fdt_fixup_memory_banks. This chain ensures that U-Boot and Linux only
use RAM that is actually available.

The cause is that "serial,nc" forced the console subsystem to
initialize the ethernet driver before ethernet subsystem
initialization (console_init_r() is called before initr_net()).
During the mtk_eth driver initialization, mdio_register() will be
called, and miiphy_get_dev_by_name() will then be called.
The miiphy_get_dev_by_name() will check the list "mii_devs" to see
if the passed device name exists. However the mii_devs is defined
without initialization:
> static struct list_head mii_devs;
and the actual initialization is done in the following chain:
initr_net -> eth_initialize -> eth_common_init -> miiphy_init
Since initr_net() hasn't be called, iterating over the mii_devs
will access to physical address 0 (mii_devs.next == NULL) and will
cause the crash.
The fix is to define mii_devs using:
> static LIST_HEAD(mii_devs);
As the "current_mii" is defined as a static variable, it will
always be NULL in board_r stage and initializing it will NULL is
unnecessary. So the entire miiphy_init() can be remove.

The current code has a problematic corner case with formar "%c" and
0 as parameter. The proper zero byte is being emitted into digit buffer
but the final copy into outstr expects null-terminated string and doesn't
copy the required \0 byte. This has lead to malformed TFTP packets, refer
to tftp_send() which relies on %c to generate multiple zero-terminated
strings in one buffer.
Introduce a variable to force the copy of one character in this case.
The new behaviour is consistent with non-tiny implementation.

Line 171 in README is describing that before relocation
no code should use global variable because global variables
are placed to BSS section which is initialized to 0 after
relocation.
On Versal platforms clock driver is initialized before
relocation (via using dm,bootph-all flag in DT) and global
variables are initialized which works if this is used only
before relocation. But the variables are used after
relocation too but values are zeroed which is ending up
incorrect behavior.
That's why place variables to data section to ensure that
values are not cleared which is for now the quickest
temporary solution. The correct way to do it is to move
all global variables to private data to avoid it.

When an error is detected in the TSEC receive path, the driver currently
prints an error message, but leaves the corresponding packet descriptor
in its old state (i.e. owned by the CPU side). As a result, the packet
queue can be starved of available buffers if enough errors happen.
To recover from errors, re-arm the packet buffer descriptor after an
error has been detected.
Errors can be provoked by changing a PHY with phy-mode = "rgmii-id" to
phy-mode = "rgmii".
