The OUTPUT_FORMAT command in linker scripts
was always misused due to some endianess and
toolchain problems.
Use GCC flags to ensure proper output format,
and get rid of the OUTPUT_FORMAT commands in
the board specific u-boot.lds files.

By now U-Boot supports Qemu MIPS for little and big endian
as well as 32 bit and 64 bit. Update and fix the example usage
in the README to reflect this.

Using the example command from the README file does
not work as expected. qemu shows a text similar to
the one below and it hangs.
$ qemu-system-mips -L . -nographic
Could not open option rom 'pxe-pcnet.rom': No such file or directory
qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
qemu: terminating on signal 15 from pid 19726
This happens because qemu emulates a Malta board by
default if the machine type is not defined explicitely
on the command line.
For a working test, the '-M mips' switch is required:
$ qemu-system-mips -M mips -L . -nographic
Could not open option rom 'vgabios.bin': No such file or directory

The 'Limitations & comments' section refers to the
'-m mips' switch which is not valid. The '-m' switch
can be used for setting the virtual RAM size:
$qemu-system-mips --help | grep '^-m '
-m megs set virtual RAM size to megs MB [default=128]
$
The correct switch for specifying the machine type is '-M'.
Fix the text to refer to that.

The command declaration now uses the new LG-array method to generate

This fixes the build of the two sh boards shmin and r7780mp and qemu-mips
which currently fail to build due to dropped pre-CONFIG_NET_MULTI code.
This v2 patch minimizes the number of lines in the diff for easy review
and to eliminate any possible accidential changes resulting from moving
lines of code in the file. This also makes the register function very easy.
Any cleanups and improvements are intentionally deferred to follow-up patches
to keep this patch as simple and as easy to review as possible.
A new driver register function, ne2k_register() calls the existing
one-time setup part of the old init function and calls eth_register().
Changes to shmin, r7780mp and qemu-mips:
- Call the new ne2k_register() from board_eth_init() of the boards.
- Tested using qemu-mips board,
- Tested the two renesas / sh boards r7780mp and shmin to compile again,
and should work.
checkpatch-clean when "--ignore VOLATILE" is added to .checkpatch.conf,
and no warnings introduced in none of the three boards using this driver.

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.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.
This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Current assembler codes are inconsistent in the way of register jump
instruction usage; some use jr, some use j. Of course GNU as allows both
usages, but as can be expected from `Jump Register' the mnemonic `jr' is
more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage
at all.
