This patch adds macros which allow for the instrumentation of UBoot boot

Under normal operation the bootm command will never return - this patch adds
additional instrumentation to signal the 'end' of the bootm command such that
this point can be reflected in any bootgraph SVG.

Hi,
I've not used that - but have used -finstrument-functions which works fairly
well. The difficulty is figuring out what to do during the extra calls it
generates.

indicates something is not ideal. Instead it renames the exiting 'Loading'

all together when the move operation doesn't occur.

been seen before? Is there any reason why a large delay would be required
between the very first COMMAND and DATA phase vs subsequent phases - and if
so is there value in changing UBoot to support this?

han wonder if U-Boot even
started the kernel. The second is that I've seen a few times in the
past where setting console to nothing (console=) results in strange
behavior (it once increased boot time). After all we want a console we
just don't want to use it as
'silent' feature isn't the correct way
to achieve it. If a user depends on having a console completely free then
they probably shouldn't add a 'console=xyz' to their boot args in the first
place.
Thanks,
Andrew Murray

change that to 'console='
(which shouldn't ought to make a difference anyway).
Where a user has 'console=null' in their bootargs, then my console
would turn that into 'console=null loglevel=1' rather that the present
which would be 'console='.
Thanks,
Andrew Murray
