There are three different kinds of EEPROM possibly present on boards.
1. 1byte address. For those we should avoid 2byte address in order
not to rewrite the data. Second byte of the address can potentially
be interpreted as the data to write.
2. 2byte address with defined behaviour. When we try to use 1byte
address they just return "FF FF FF FF ... FF"
3. 2byte address with undefined behaviour (for instance, 24LC32AI).
When we try to use 1byte address, then their internal read
pointer is changed to some value. Subsequential reads may be
broken.
To gracefully handle both case #1 and case #3 we read all required
data from EEPROM at once (about 80 bytes). So either all the data is
valid or we fallback to 2byte address.
common/console.c: prevent pre-console buffer contents from being added to itself
I do not have any non-serial output devices, so a
print_pre_console_buffer(PRE_CONSOLE_FLUSHPOINT2_EVERYTHING_BUT_SERIAL)
does nothing for me.
However, I was manually inspected the pre-console buffer using md.b,
and I noticed that the early part of it was repeated. The reason is
that the first call of print_pre_console_buffer(), from
console_init_f(), ends up invoking puts() with the contents of the
buffer at that point, and puts() at that point ends up in the else
branch of
if (gd->flags & GD_FLG_DEVINIT) {
/* Send to the standard output */
fputs(stdout, s);
} else {
/* Send directly to the handler */
pre_console_puts(s);
serial_puts(s);
}
so indeed the contents is added again.
That can be somewhat confusing (both when reading the buffer manually,
but also if it did actually come out on some device). So disable all
use of the pre-console buffer while print_pre_console_buffer() is
emitting it.

distroboot: ubifs: Add support for specifying UBI header offset
Some UBI partitions may use non-standard UBI header offset. For attaching
these UBI partitions it is required to pass second argument with offset to
"ubi part" command.
Therefore extend distroboot to allow specifying additional optional 6th
argument with UBI header offset. This offset is set in new distroboot
variable ${bootubioff} which may be used by distroboot script to e.g.
properly pass this value to linux kernel command line for proper mounting
of rootfs by kernel. This variable is set to empty string (cleared) when
UBI header offset is not specified into distroboot BOOT_TARGET_DEVICES
macro.
Usage of helper macro BOOTENV_DEV_UBIFS_BOOTUBIOFF in this change is there
as a type check. It ensures that in BOOT_TARGET_DEVICES macro was specified
UBIFS func with either 5 or 6 arguments. If not then cpp throws compile
error.

mbus driver is initialized from arch_cpu_init() callback which is called

pointers into global variables, so it is data position dependent.
Therefore after relocations all pointers are invalid and driver does not
work anymore as all pointers referes to the old memory, which overlaps with
CONFIG_SYS_LOAD_ADDR and ${loadaddr}.
For example U-Boot fuse command crashes if loadaddr memory is cleared or
rewritten by some image loaded by U-Boot load command.

fuse read 0 1 2
