instead of throwing all output away when the console
is not initialized, buffer it in a kfifo and print
it later when the first console gets initialized.

We use FIFOs on some devices, so flush them before exiting so
we do not get funny characters in the output.

Some devices, especially the ones doing DMA should be disabled before
giving control to an OS. We take the simple approach here: Just shutdown
the devices in the reverse order they were activated.

Issue:
Compiling on Ubuntu 8.10 Fails:
inlined from 'envfs_save' at scripts/../common/environment.c:135:
/usr/include/bits/fcntl2.h:51: error: call to '_open_missing_mod'
declared with attribute error: open with O_CREAT in second argument
needs 3 arguments
Usage: open(filename, O_WRONLY | O_CREAT)
Fix:
When using open with O_CREAT, it requires
mode to be defined.

This patch removes adding of an additional \ when doing
echo "\""
which gives \" instead of just "
I checked in latest busybox hush and this code is still present there,
but it behaves correctly in busybox due to some other code pathes I
didn't investigate.
If this change has any unwanted side effects feel free to flame on me

Add an own device id for partitions. This is necessary to allow
the partition layer to check if the given device is really a partition.
Also, check for readonly flag in erase.

[Patch 02/17] U-Boot-V2: Handle case of clock rollover for get_time_ns
get_time_ns does a simplistic delta = cycle_now - cycle_last. It is possible that the h/w counter reached max and reset back to 0.
This patch addresses this issue by checking for rollover condition.
NOTE 1: This does not guarentee that you cannot confuse get_time_ns. You could possibly wait for two reset cycles and then get a messed up value.
To fix that we may need interrupt mode timer tick - something on the lines of jiffies on linux.
NOTE 2: the question of cs->mask is not clear. if the mask is for the tick, then it is better done with (cycle_now & cs->mask) - (cs->cycle_last & cs->mask).

Memory layout can now be specified via kconfig options. Two
possibilities exist: default layout means the layout is stack
/ malloc heap / U-Boot. The user can also specify fixed addresses
for each TEXT_BASE / stack / malloc heap.
as we rather use positive logic. Make it dependent on boards that
have it rather than on ARM
