Suzuki Poulose 0f890c8d20 powerpc: Rename mapping based RELOCATABLE to DYNAMIC_MEMSTART for BookE
The current implementation of CONFIG_RELOCATABLE in BookE is based
on mapping the page aligned kernel load address to KERNELBASE. This
approach however is not enough for platforms, where the TLB page size
is large (e.g, 256M on 44x). So we are renaming the RELOCATABLE used
currently in BookE to DYNAMIC_MEMSTART to reflect the actual method.

The CONFIG_RELOCATABLE for PPC32(BookE) based on processing of the
dynamic relocations will be introduced in the later in the patch series.

This change would allow the use of the old method of RELOCATABLE for
platforms which can afford to enforce the page alignment (platforms with
smaller TLB size).

Changes since v3:

* Introduced a new config, NONSTATIC_KERNEL, to denote a kernel which is
  either a RELOCATABLE or DYNAMIC_MEMSTART(Suggested by: Josh Boyer)

Tony Breeds 3b3bceef26 net: fix IBM EMAC driver after rename.
In commit 9aa3283595 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*

The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors).  In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.

We do not explicitly select the Kconfig dependencies, as this would force
EMAC on.  Doing it in the defconfig allows more flexibility.

Tested on a canyondlands board.

Dave Kleikamp 9661534d6a powerpc/47x: allow kernel to be loaded in higher physical memory
The 44x code (which is shared by 47x) assumes the available physical memory
begins at 0x00000000.  This is not necessarily the case in an AMP
environment.

Support CONFIG_RELOCATABLE for 476 in order to allow the kernel to be
loaded into a higher memory range.

Stephen Rothwell ff56535d29 powerpc: Restore some misc devices to our configs
Uwe Kleine-König reported:

	while working on an defconfig (arm/mx27) I noticed that just updating
	it[1] results in removing CONFIG_EEPROM_AT24=y.  The reason is that
	since commit

		v2.6.36-5965-g5f2365d (misc devices: do not enable by default)

	MISC_DEVICES isn't enabled anymore by default.  So all defconfigs that
	have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
	MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
	problem.

This restores those misc devices to the powerpc defconfigs.

David Rientjes 6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
