The handling of env_hwconfig, board_hwconfig, and cpu_hwconfig got
broken when we removed the boards defining dummy board_hwconfig
& cpu_hwconfig values.
We fix this by handling the various strings in priority order. If
hwconfig_parse returns NULL for a given string we check the next one
in order (env_hwconfig, board_hwconfig, followed by cpu_hwconfig).

Since board_hwconfig & cpu_hwconfig are defined as weak and dont have a
default value they will get put into the BSS if they aren't defined
elsewhere. This is problematic as we try to utilize hwconfig before
we've relocated and thus BSS isn't setup.
Instead of giving dummy values in the board files that utilize this
feature, we can just initialize the variables to an empty string and
thus move them out of the BSS if they aren't defined elsewhere.
Also made board_hwconfig & cpu_hwconfig arrays to reduce size associated
with string pointers vs arrays.

Rather than add runtime overhead of installing completion handlers, do it
statically at build time. This requires a new build time helper macro to
declare a command and the completion handler at the same time. Then we
convert the env related funcs over to this.
This gives an opportunity to also unify the U_BOOT_CMD macros.

Since we set #define MORECORE_CLEARS 1, the code assumes 'sbrk' always
returns zero'd out memory. However since its possible that free()
returns memory back to sbrk() via malloc_trim we could possible get
non-zero'd memory from sbrk(). This is a problem for when code might
call calloc() and expect the memory to have been zero'd out.
There are two possible solutions to this problem.
1. change #define MORECORE_CLEARS 0
2. memset to zero memory returned to sbrk.
We go with the second since the sbrk being called to free up memory
should be pretty rare.
The following code problems an example test to show the issue. This
test code was inserted right after the call to mem_malloc_init().
...
u8 *p2;
int i;
printf("MALLOC TEST\n");
p1 = malloc(135176);
printf("P1 = %p\n", p1);
memset(p1, 0xab, 135176);
free(p1);
p2 = calloc(4097, 1);
printf("P2 = %p %p\n", p2, p2 + 4097);
for (i = 0; i < 4097; i++) {
if (p2[i] != 0)
printf("miscompare at byte %d got %x\n", i, p2[i]);

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.

This change does the following:
- Removes the printing of the PCI interrupt line value. This is
normally set to 0 by U-Boot on bootup and is rarely used during
everyday operation.
- Prints out the PCI function number of a device. Previously a device
with multiple functions would be printed identically 2 times, which is
generally confusing. For example, on an Intel 2 port gigabit Ethernet
card the following was displayed:
...
04 01 8086 1010 0200 00
04 01 8086 1010 0200 00
...
- Prints a text description of each device's PCI class instead of the
raw PCI class code. The textual description makes it much easier to
determine what devices are installed on a PCI bus.
- Changes the general formatting of the PCI device output.

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support. However, other recent changes led to a different
implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.
So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

Since we use hwconfig in cases before relocation (like getting DDR
params on FSL PPC systems), we can have strings that exceed the early
small (32 byte) buffer size that getenv will handle.
So we explicitly allocate our own buffer on the stack and use if to
handle getting the hwconfig env string. We currently utilize a string
length of 128 bytes.
This allows us to get rid of boot messages like:

The device tree (fdt) must always exist in within the bootmap (usually the
first 16MB of RAM). If it doesn't, then boot_relocate_fdt() will allocate
an LMB region in the bootmap and copy the fdt into that region. It will
also increase the size of the fdt.
If the fdt is already in the bootmap, then previously the memory was just
reserved. There was no contingency if the reservation failed, however.
By always allocating an lmb region and copying/resizing the fdt into that
region, the code is simplified and the memory region is always allocated
properly.
Also change the types of some variables to avoid some typecasts.

Having nios2 and microblaze do so as well removes code from

a nasty ifdef from bootm_start.
In the case where boot_get_fdt returns an error bootm_start
