It seems that gcc 6.3 at least is smart enough to warn about the _val
variable being unassigned in the default case in the set_hdr_field()
macro, but not smart enough to figure out that the default case is never
taken. This results in warnings such as the following:
pfx##hdr32[idx].field = _val; \
^
../tools/mips-relocs.c:51:11: note: _val was declared here
uint64_t _val; \
^
../tools/mips-relocs.c:88:2: note: in expansion of macro set_hdr_field
set_hdr_field(p, idx, field, val)
^~~~~~~~~~~~~
../tools/mips-relocs.c:408:3: note: in expansion of macro set_phdr_field
set_phdr_field(i, p_filesz, load_sz);
^~~~~~~~~~~~~~
../tools/mips-relocs.c: In function main:
../tools/mips-relocs.c:77:25: warning: _val may be used uninitialized
in this function [-Wmaybe-uninitialized]
Avoid this by assigning _val = 0 in the default case, and asserting that
we didn't actually hit it for good measure.
For reference gcc 7.1.1 seems to be smart enough to not hit the above
warning without this patch.

This patch fixes 2 bugs introduced by the following commit
2bb5b63 MIPS: bootm: rework and fix broken bootm code
The CONFIG_IS_ENABLED macro prepends 'CONFIG_' Hence, remove CONFIG_
from CONFIG_MIPS_BOOT_ENV_LEGACY usage.
Also, 2bb5b63 reworks bootm so that linux_env_legacy runs before
linux_cmdline_legacy. However, linux_env_legacy depends on
linux_cmdline_legacy running first as linux_cmdline_init initialilzes
linux_argp which linux_env_legacy later depends on during its
initialization.
Reorder the code so that linux_cmdline_legacy runs before
linux_env_legacy.

U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.
Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:
8f998064 lw t9,-32668(gp)
0320f809 jalr t9
Without -fpic the call is simply:
0f803f01 jal be00fc04 <puts>
This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.
Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:
3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9
Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.
This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.
Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

There are a bunch of protocols which should be exposed by GUID but are
not. Add a helper macro to create an efi_object, to avoid much typing.
Note that using the pointer for efiobj->handle is semi-arbitrary. We
just need a unique value to match the efiobj supporting the protocol
with the handle that LocateHandle() returns..
See LibLocateProtocol() in gnu-efi. It does LocateHandle() to find all
the handles, and then loops over them calling HandleProtocol() with the
GUID of the protocol it is trying to find.

reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo()
or mpc86xx_reginfo() based on CONFIG_ symbol.
As those 3 functions can't me defined at the same time, let's
rename them print_reginfo() to avoid the #ifdefs
The name is kept generic as it is not at all dependent on
powerpc arch and any other arch could want to also print
such information.
In addition, as the Makefile compiles cmd/reginfo.c only when
CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD
definition inside a #ifdef CONFIG_CMD_REGINFO
Lets all remove the #ifdefs around the U_BOOT_CMD as this
file is only compiled when CONFIG_CMD_REGINFO is defined
Finally, this is a PowerPC-only command, disable it on a number of
non-PowerPC platforms.
