$(call cc-option,...) is useful but costly.

- Export many variables

If we want to set variables in config.mk and use them

We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.
By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)
Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.
It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding
Many (but not all) of Blackfin boards give -O2 option
to compile under lib/ directory.
That means lib/ should be speed-optimized,
whereas other parts should be size-optimized.
We want to keep the same behavior,
but do not want to parse board/*/config.mk again and again.
We've got no choice but to invent a new method.
CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED, if it is enabled,
gives -O2 flag only for building under lib/ directory.
Dirty codes which I had marked as "FIX ME"
in board/${BOARD}/config.mk have been deleted.
Instead, CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED has been
defined in include/configs/${BOARD}.h.

ppc4xx: Remove 4xx NAND booting support
As ppc4xx currently only supports the deprecated nand_spl infrastructure
and nobody seems to have time / resources to port this over to the newer
SPL infrastructure, lets remove NAND booting completely.
This should not affect the "normal", non NAND-booting ppc4xx platforms
that are currently supported.

unit-test: make "test -e" test independent of $CWD
The unit-test for hush's "test -e" currently relies upon being run in
the U-Boot build directory, because it tests for the existence of a file
that exists in that directory.
Fix this by explicitly creating the file we use for the existence test,
and deleting it afterwards so that multiple successive unit-test
invocations succeed. This required adding an os.c function to erase
files.

hush: fix some quoted variable expansion issues
The following shell command fails:
if test -z "$x"; then echo "zero"; else echo "non-zero"; fi
(assuming $x does not exist, it prints "non-zero" rather than "zero").
... since "$x" expands to nothing, and the argument is completely
dropped, causing too few to be passed to -z, causing cmd_test() to
error out early.
This is because when variable expansions are processed by make_string(),
the expanded results are concatenated back into a new string. However,
no quoting is applied when doing so, so any empty variables simply don't
generate any parameter when the combined string is parsed again.
Fix this by explicitly replacing quoting any argument that was originally
quoted when re-generating a string from the already-parsed argument list.
This also fixes loss of whitespace in commands such as:
setenv space " "
setenv var " 1${space}${space} 2 "
echo ">>${var}<<"

net: asix: don't pad odd-length TX packets
For Ethernet/USB RX packets, the ASIX HW pads odd-sized packets so that
they have an even size. Currently, asix_recv() does remove this padding,
and asic_send() adds equivalent padding in the TX path. However, the HW
does not appear to need this packing for TX packets in practical testing
with "ASIX Elec. Corp. AX88x72A 000001" Vendor: 0x0b95 Product 0x7720
Version 0.1. The Linux kernel does no such padding for the TX path.
Remove the padding from the TX path:
* For consistency with the Linux kernel.
* NVIDIA has a Tegra simulator which validates that the length of USB
packets sent to an ASIX device matches the packet length value inside
the packet data. Having U-Boot and the kernel do the same thing when
creating the TX packets simplifies the simulator's validation.
