When I migrated this to Kconfig in commit 68e54040ccc3 ("sandbox: Move
CONFIG_IO_TRACE to Kconfig") I didn't look hard enough for other
details. As explained in the README, this is valid for ARM too. So start
by making this be a prompted question and CMD_IOTRACE depend on IO_TRACE
being enabled. Next, migrate the information out of README and in to
the appropriate help text for existing options in Kconfig. Finally, make
this option be default y on SANDBOX but not selected as it's valid to
build without it.

Add initjm[() to sandbox, a non-standard extension to setjmp()/
longjmp() allowing to initialize a jump buffer with a function pointer
and a stack pointer. This will be useful to later introduce threads.
With this new function it becomes possible to longjmp() to a particular
function pointer (rather than to a point previously reached during
program execution as is the case with setjmp()), and with a custom stack.
Both things are needed to spin off a new thread. Then the usual
setjmp()/longjmp() pair is enough to save and restore a context, i.e.,
switch thread. The implementation is taken verbatim from barebox [1] with
the exception of the additional stack_sz argument. It is quite complex
because contrary to U-Boot platform code we don't know how the system's
C library implements the jump buffer, so we can't just write the function
and stack pointers into it.

At this point in time, DM is always enabled. So if MMC is enabled, it
should select DM_MMC. No drivers need to depend on DM_MMC being enabled
now, so remove that from dependency lists. This now means that a number
of platforms which select'd DM_MMC need to select MMC instead. This also
fixes a migration problem with espresso7420 in that MMC is built again

Generally speaking, we do not prompt for this value and define it in the
board specific Kconfig file. There are some valid use cases however
today where we do prompt for this value, so instead of having this be
done in a number of locations, do this at the top-level location only.
This removes the question from a number of other locations and makes it
consistent that when we do set the value directly, we always do it the
same way. We don't need to specify the type, it's always string.

The help for CONFIG_MTD explains that it needs to be enabled for various
things like NAND, etc to be available. It however then doesn't enforce
this dependency and so if you have none of these systems present you
still need to disable a number of options. Fix this by making places
that select/imply one type of flash, but did not do the same, also do
this for "MTD". Make boards which hadn't been enabling MTD already but
need it now, do so. In a few places, disable CONFIG_CMD_MTDPARTS as it
wasn't previously enabled but was now being implied.

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.
With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

CONFIG_TIMER drivers are designed differently that timer is free running up

Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.
By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.
The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
sections are empty. relocate-rela will fill them and output file is
u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections
Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).
