U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again. On some architectures
(especially ARM) this results in a large number of calls to gcc.
This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.
Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board>
-> grep execve /tmp/foo | wc -l
Before: After: Reduction:
==================================
P2020DS 20555 15205 -26%
qong 31692 14490 -54%
As a result, built times are significantly reduced, typically by
30...50%.

GNU Makefile have two flavors of variables, recursively expanded that is
defined by using '=', and simply expanded that is defined by using ':='.
The bug is caused by using recursively expanded flavor for BIN and SREC.
As you can see below, they are prepended by $(obj) twice.
We can reproduce this bug with a simplified version of this Makefile:
$ cat >Makefile <<\EOF
obj := /path/to/obj/
ELF := hello_world
BIN_rec = $(addsuffix .bin,$(ELF)) # recursively expanded
BIN_sim := $(addsuffix .bin,$(ELF)) # simply expanded
ELF := $(addprefix $(obj),$(ELF))
BIN_rec := $(addprefix $(obj),$(BIN_rec))
BIN_sim := $(addprefix $(obj),$(BIN_sim))
show:
@echo BIN_rec=$(BIN_rec)
@echo BIN_sim=$(BIN_sim)
.PHONY: show
EOF
$ make show
BIN_rec=/path/to/obj//path/to/obj/hello_world.bin
BIN_sim=/path/to/obj/hello_world.bin

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.

Using -fno-toplevel-reorder causes gcc to not reorder functions. This
ensures that an application's entry point will be the first function in
the application's source file.
This change, along with commit 620bbba524
should cause a standalone application's entry point to be at the base of
the compiled binary. Previously, the entry point could change depending
on gcc version and flags.
Note -fno-toplevel-reorder is only available in gcc version 4.2 or
greater.

Previously, standalone applications were compiled with gcc flags that
produced relocatable executables on the PowerPC architecture (eg with
the -mrelocatable and -fPIC flags). There's no reason for these
applications to be fully relocatable at this time since no relocation
fixups are performed on standalone applications.
Additionally, removing the gcc relocation flags results in the entry
point of applications residing at the base of the image. When
a standalone application was relocatable, the entry point was generally
located at an offset into the image which was confusing and prone to
errors.
This change moves the entry point of PowerPC standalone applications
from 0x40004 (usually) to 0x40000.

Some versions of 'make' do not handle trailing white-spaces
properly. Trailing spaces in ELF causes a 'fake' source to
be added to the variable COBJS; leading to build failure
(listed below). The problem was found with GNU Make 3.80.
Using text-function 'strip' as a workaround for the problem.

Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in

Atmel DataFlashes by default operate with pages that are slightly bigger
than normal binary sizes (i.e. many are 1056 byte pages rather than 1024
bytes). However, they also have a "power of 2" mode where the pages show
up with the normal binary size. The latter mode is required in order to
boot with a Blackfin processor, so many people wish to convert their
DataFlashes on their development systems to this mode. This standalone
application does just that.

The attached patch corrects an error in the examples/Makefile which
causes the applications in the examples directory to hang on OMAP3
based boards. The current Makefile sets -Ttext during linking to
0x0c100000 which is outside of addressable SDRAM memory. The script
corrects the existing ifeq...else...endif logic to look at the VENDOR
tag rather than the CPU tag.
The patch affects the following configs: omap3_beagle_config,
omap3_overo_config, omap3_evm_config, omap3_pandora_config,
omap3_zoom1_config and omap3_zoom2_config.

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
