people sometimes do crazy stuff like building really large static
arrays into their kernels or building allyesconfig kernels. Give
more space to the kernel and push modules up a bit: kernel has
512 MB and modules have 1.5 GB.
Should be enough for a few years ;-)

This patch separates the current code into i.MX2 and i.MX3 and modifies
the Kconfig files to reflect this separation in the menus.
Things happend since last review:
- make i.MX3 compile again
- fix some structure names to be conform with all the shared/common
sources from i.MX1/i.MX2
Previous changes:
- stay conform to other Kconfig files (note from Russell King)

Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent
infrastructure:
- Clocksource gives sub-microsecond timestamp precision, assuming
memory is clocked at over 16 MHz. It's less than a 32 bit counter,
unless it's is also generating IRQs.
- Clockevent device supports periodic mode only; no oneshot
support from this hardware. No IRQs generated unless it's the
active clocksource.
Later, another timer (probably from a TC module) can provide a oneshot
clockevent device to get NO_HZ and High-Res-Timer behavior.
This also updates the timekeeping to use the actual master clock rate
on the system, instead of compile-time <asm/arch/timex.h> constants
matching what Atmel's EK boards use. (Product boards may well differ!)
Plus cleanup: rename "*_timer*" symbols to "*_pit*" (there are other
timers, but only one PIT); shorter lines; remove needless CPP stuff;
make several symbols static; etc.

All the SAM9 boards supported by mainline and the AT91 patches have
been converted to the new-style UART initialization. Therefore drop
support for the old at91_init_serial() interface for SAM9.
at91_uarts[] array can also be marked as __initdata.
The warning that no serial-console is defined moved from
at91_set_serial_console() to at91_add_device_serial() since the whole
point is the board-specific file is not calling
at91_set_serial_console().

Currently USB Host isn't functional on the MPC8315E boards, for two
reasons as described below.
MPC8315 Reference Manual says:
"The USB DR unit must have the same clock ratio as the encryption core
unit, unless one of them has its clock disabled."
The encryption core also drives I2C clock, so it is enabled and is equal
to 01. That means USBDRCM should be 01 here.
Plus, according to MPC8315E-RDB schematics, USB unit consumes CLK_IN
clock from the 24.00MHz oscillator, which means we must adjust REFSEL
bits as well.
p.s.
Idially we should rework whole 83xx/usb.c code, in two steps:
1. Move SCCR code to the U-Boot;
2. Implement fsl,usb-clock property in the device tree, so usb.c could
decide what clock exactly to use on per-board basis.
Though, today we're not in a hurry since there is just one 8315e board
out there.

The rheap allocation function, rh_alloc, could call kmalloc with GFP_KERNEL.

Legacy HP ia64 platforms currently cannot provide
/proc/cpuinfo/physical_id due to legacy SAL/PAL implementations.
However, that physical topology information can be obtained
via ACPI.
Provide an interface that gives ACPI one last chance to provide
physical_id for these legacy platforms. This logic only comes
into play iff:
- ACPI actually provides slot information for the CPU
- we lack a valid socket_id
Otherwise, we don't do anything.
Since x86 uses the ACPI processor driver as well, we provide a nop
stub function for arch_fix_phys_package_id() in asm-x86/topology.h

Commit 113134fcbc changed the flow of
control when calling PAL_LOGICAL_TO_PHYSICAL and SAL_PHYSICAL_ID_INFO.
With the change, if a platform did not implement the latter, a useless
printk would appear in the boot log:
ia64_sal_pltid failed with -1
So let's check the return code and only printk on a true error, and do
not print anything in the unimplemented case. While we're in there,
clean up some stylistic issues too.

The current orion5x board ->map_irq() routines check whether a
given bus number lives on the PCIe controller by comparing it with
the PCIe controller's primary bus number. This doesn't work in
case there are multiple buses in the PCIe domain, i.e. if there
exists a PCIe bridge on the primary PCIe bus.
This patch adds a helper function (orion5x_pci_map_irq()) that
returns the IRQ number for the given PCI device if that device has
a hard-wired IRQ, or -1 otherwise, and makes each board's
->map_irq() function use this helper function.
