e261c83aa0 ARM: VExpress: enable ARMv7 virt support for VExpress A15
To enable hypervisors utilizing the ARMv7 virtualization extension
on the Versatile Express board with the A15 core tile, we add the
required configuration variable.
Also we define the board specific smp_set_cpu_boot_addr() function to
set the start address for secondary cores in the VExpress specific
manner.
There is no need to provide a custom smp_waitloop() function here.

This also serves as an example for what to do when adding support for
new boards.

cd4f46e1ef ARM: vexpress: create A5 specific board config
This patch creates a new config for the A5 dual core tile that includes the

The generic config has been modified to provide support for the Extended
Memory Map, as used on the A5 core tile.  A5 does not support the legacy
memory map.

fca94c3fd5 integrator: remove fragile delay loop from PCI code
The reference implementation of the PCI initialization code almost
everywhere contain this fragile loop of "a few usecs", and its
use of volatile variables to delay a number of bus cycles is indeed
uncertain.

Reading the manual "Integrator/AP Users Guide", page 5-15 it is
clearly stated:

"Wait until 230ms after the end of the reset period before
accessing V360EPC internal registers. The V360EPC supports the
use of a serial configuration PROM and the software must wait for
the device to detect the absence of this PROM before accessing any
registers. The required delay is a function of the PCI Clock, but
at the lower frequency (25MHz) is 230ms".

So let's simply wait 230ms per the spec.

This solves the compilation error that looked like this:
pci.c: In function ‘pci_init_board’:
pci.c:286:18: warning: variable ‘j’ set but not used

2458716a5b integrator: rewrite the AP PCI driver
The PCI support for the Integrator AP has apparently never
been finished and I strongly suspect that it has never worked,
so let's fix it. This is a list of the more or less
un-splittable changes done in this driver rewrite:

- Replace the register definitions stashed into the config
  file (!) with a copy if the register file from the Linux
  kernels arch/arm/include/asm/hardware/pci_v3.h

- Delete the unreadable gigantic macros that perform the
  config accesses and replace them with copyedited code from
  Linux arch/arm/mach-integrator/pci_v3.c

- Rewrite the rest of the setup code to use the
  v3_[read|write][lwb]() accessors.

- Enable PCI by default in the AP board configuration.

- Fix checkpatch warnings and make code more conformant.

701ed16e23 integrator: make flash writeable on boot
This reconfigures the EBI (External Bus Interface) on the
integrator so that chip select 1, handling the flash memory, is
set to writeable. Without this it is not possible for U-Boot to
access flash memory and it crashes on startup since CFI won't
work properly.

Since this is the first time we use the EBI, we create a header
file for its registers.

46b5ccbfe2 integrator: do not test first part of the memory
When booting from Flash, the Integrator remaps its flash memory
from 0x24000000 to 0x00000000, and starts executing it at
0x00000000. This ROM thus hides the RAM underneath and first
0x40000 bytes of the memory cannot be tested by get_ram_size().
So let's test from 0x40000 to the end of detected memory
instead.

23b3ae0fe8 integrator: convert to new build system
This deletes the integrator split_by_variant.sh script and
defines a number of unique board types for the core modules
that are meaningful to support for the Integrator AP/CP, i.e.
the ones that did not just say "unsupported core module" in
split_by_variant.sh. If more core modules need to be supported
they are easy to add.

We delete all the old cruft in Makefile and MAKEALL that was
working around the old way of building boards. We create a
unique config file per board to satisfy the build system, but
they are just oneliners that include the existing
integratorap.h and integratorcp.h configs.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
