The QEMU targets have plenty of RAM now and the current value
specified wasn't a multiple of a 4K page.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
Previously we were instantiating QEMU with 32MB of RAM but
only enabling a small fraction of it.
Now we boot with 8MB of ram. We ignore the first 4K so we can
make that an unmapped paged to catch NULL pointer dereferences.
If XIP is enabled, the "ROM" region will be the first half of
memory, the "RAM" region the latter.
Move the IDT_LIST and MMU_LIST regions elsewhere so they don't
overlap the new memory arrangement.
Use !XIP to fix a problem where CONFIG_RAM_SIZE was set incorrectly
for XIP case.

These special kernel sections represent arrays of kernel objects than
are iterated over at runtime to perform initialization.
The code expects all the data in these sections to be in the form of an
array of that section type, with each element sizeof(type) bytes apart.
Unfortunately, the linker sometimes has other plans and in some cases
was defaulting to aligning the data to some large power-of-two value,
such as 64 bytes. This causes any attempt to iterate over these sections
to fail as they are not a proper array.
Use the ld SUBALIGN() directive to force the alignment of these input
sections to 4 bytes.

Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.
