464c79207c punt unused clean/distclean targets
The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used.  Punt them all.

MAKEALL didn't report any errors related to this that I could see.

7e4c3a41ce xilinx-ppc4xx-generic: Fix Makefile to work with MAKEALL
config.mk only mkdirs $(obj), but we have objects shared with other
boards located on other dirs.

This patch mkdirs the needed dirs for the xlnx-generic boards.

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.

9aef738885 unify HOST_CFLAGS and HOSTCFLAGS
The top build system sets up HOSTCFLAGS a bit and exports it, but other
places use HOST_CFLAGS instead.  Unify the two as HOSTCFLAGS so that the
values stay in sync.

e07f4a8033 ppc44x: Unification of virtex5 pp440 boards
This patch provides an unificated way of handling xilinx v5 ppc440 boards.

It unificates 3 different things:

1) Source code
A new board called ppc440-generic has been created. This board includes
a generic tlb initialization (Maps the whole memory into virtual) and
defines board_pre_init, checkboard, initdram and get_sys_info weakly,
so, they can be replaced by specific functions.

If a new board needs to redefine any of the previous functions
(specific initialization) it can create a new directory with the
specific initializations needed. (see the example ml507 board).

2) Configuration file
Common configurations are located under configs/xilinx-ppc440.h, this
header file interpretes the xparameters file generated by EDK and
configurates u-boot in correspondence. Example: if there is a Temac,
allows CMD_CONFIG_NET
Specific configuration are located under specific configuration file.
(see the example ml507 board)

3) Makefile
Some work has been done in order to not duplicate work in the Main
Makefile. Please see the attached code.

In order to support new boards they can be implemented in the next way:

a) Simple Generic Board  (90% of the time)
Using EDK generates a new xparameters.h file, replace
ppc440-generic/xparameters.h  and run make xilinx-ppc440-generic_config
&& make

b) Simple Boards with special u-boot parameters (9 % of the time)
Create a new file under configs for it (use ml507.h as example) and
change your paramaters. Create a new Makefile paragraph and compile

c) Complex boards (1% of the time)
Create a new folder for the board, like the ml507

Finally, it adds support for the Avnet FX30T Evaluation board, following
the new generic structure:

Cheap board by Avnet for evaluating the Virtex5 FX technology.

This patch adds support for:
 - UartLite
 - 16MB Flash
 - 64MB RAM

Prior using U-boot in this board, read carefully the ERRATA by Avnet
to solve some memory initialization issues.
