This patch makes the on-board RTC work on the socfpga_socrates board.
This rtc is present on the board, but it does not work (fails with a
timeout).
This patch adds a weak pull-up on the I2C0-SCL pin connected to the m41t82
RTC on this board. While the SDA line has a pull-up on the pcb, the pull-up
on the SCL line seems to be missing. To work around this, enable the
weak-pull-up feature on this pin.
After applying this patch, the rtc timeout is gone and the 'date' command
can access the rtc chip.

This adds a compatible string for m41t82. This ensures that this driver
can be used for m41t82 in DM mode, too (asit was usable for this model in
non-DM mode before).
In addition, the HT bit has to be reset during probe, since the m41t82
chip sets it when entering battery standby mode.

Using this driver on socfpga gen5 with DM_I2C enabled leads to a data abort
as the 'i2c' reset property cannot be found (the gen5 dtsi does not provide
reset-names).
The actual bug was to check 'if (&priv->reset_ctl)', which is never false.
While at it, convert the driver to use 'reset_get_bulk' instead of looking
at a specific named reset and also make it release the reset on driver
remove before starting the OS.

Testing has shown that the current DM implementation of a platform /
board specific translation offset, as its needed for the SPL on MVEBU
platforms is buggy. The translation offset is confingured too late,
after the driver bind functions are run. This may result in incorrect
address translations. With the current implementation its not possible
to configure the offset earlier, as the DM code has not run at all.
This patch now removed the set_/get_translation_offset() calls and
moves the translation offset into the GD variable translation_offset.
This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled.
This option is enabled only for MVEBU on ARM32 platforms, where its
currenty needed and configured in the SPL.

Allocation routines were adjusted to ensure that the returned addresses

At present if one of the initcalls fails on sandbox the address printing
is not help, e.g.:
initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96)
This is because U-Boot gets relocated high into memory and the relocation
offset (gd->reloc_off) does not work correctly for sandbox.
Add support for finding the base address of the text region (at least on
Linux) and use that to set the relocation offset. This makes the output
better:
initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96)
Then you use can use grep to see which init call failed, e.g.:
$ grep 0000000000048134 u-boot.map
stdio_add_devices

When using boot scripts it can become quite hard to understand
which commands are actually executed during bootup (e.g. where
is a kernel image loaded from or which DTB is in use).
Shell scripts suffer from a similar problem and many shells address
this problem with a command execution tracer (e.g. BASH has xtrace,
which can be enabled by "set -x").
This patch introduces a command tracer for U-Boot, which prints
every command with its arguments before it is executed.

Our platform doesn't store the DTB into the Android image second area,
but rather copies the DTB to RAM from a dedicated dtb.img partition [0],
prior to booting the Android image by calling bootm.
Similar to [1], we find it useful to just call 'bootm' and have the
right DTB being passed to OS (assuming its address has been previously
stored in 'fdtaddr' by calling `fdt addr <dtb-addr>`).
Booting Android with DTB from 'fdtaddr' will only occur if:
- No DTB is embedded in the second area of Android image
- 'fdtaddr' points to a valid DTB in RAM

The 'no_fdt' goto label was introduced by v2015.01 commit [0] and it
had two review stages [1-2]. The *documented* purpose behind commit [0]
is (excerpt from commit description):
> allows both FDT and non-FDT kernels to boot by making the
> third parameter to the bootm/bootz optional
While [1] and [2] share the same goal, they have very different
implementations:
- [1] was based on a very simple 'argc' check at function error out
with returning success to the caller if the third parameter was NOT
passed to bootm/bootz command. This approach had the downside of
returning success to the caller even in case of legitimate internal
errors, which should halt booting.
- [2] added the "no_fdt" label and several "goto no_fdt" statements.
This allowed to report the legitimate internal errors to the caller.
IOW the major difference between [1] and [2] is:
- [1] boot w/o FDT if FDT address is not passed to boot{m,z,*}
- [2] give *freedom* to the developer to boot w/o FDT from any
(more or less) arbitrary point in the function flow (and here
comes the peculiar aspect, which looks to be a leftover from [1])
with the precondition that the 3rd argument (FDT address) is NOT
provided to boot{m,z,*}. In practice, this means that only a subset
of "goto no_fdt" end up booting w/o FDT while the other subset is
returning an error to the caller.
This patch removes the peculiar behavior described above, such that
"goto no_fdt" performs really what it tells to the developer.
The motivation of this patch is to decrease the unneeded complexity
and increase the readability of boot_get_fdt().

Paranoid programming [1] lies at the foundation of proper software
development, but the repetitive zeroing-out of output arguments in the
context of the same function rather clutters the code and inhibits
further refactoring/optimization than is doing any good.
In boot_get_fdt(), we already perform zero/NULL-initialization of
*of_flat_tree and *of_size at the beginning of the function, so doing
the same at function error-out is redundant/superfluous.
Moreover, keeping the code unchanged might encourage the developers to
update *of_flat_tree and *of_size during some interim computations,
which is against the current design of boot_get_fdt(). Currently,
writing useful data into these arguments happens just before
successfully returning from boot_get_fdt() and it should better stay so.
