eb838e7d84 usb: create common header virtual root hub descriptors
Many USB host controller drivers contain almost identical copies of the
same virtual root hub descriptors. Put these into a common file to avoid
duplication.

Note that there were some very minor differences between the descriptors
in the various files, such as:

- USB 1.0 vs. USB 1.1
- Manufacturer/Device ID
- Max packet size
- String content

I assume these aren't relevant.

2456b97f0c ush: ehci: initialize altnext pointers in QH
Section 4.10.2 "Advance Queue" of ehci-specification-for-usb.pdf
specifies how an EHCI controller loads a new QTD for processing if the
QH is not already marked as active. It states:

=====
If the field Bytes to Transfer is not zero and the T-bit in the Alternate
Next qTD Pointer is set to zero, then the host controller uses the
Alternate Next qTD Pointer. Otherwise, the host controller uses the Next
qTD Pointer. If Next qTD Pointer’s T-bit is set to a one, then the host
controller exits this state and uses the horizontal pointer to the next
schedule data structure.
=====

Hence, we must ensure that the alternate next QTD pointer's T-bit
(TERMINATE) is set, so the EHCI controller knows to use the next QTD
pointer.

5ca05c8b03 cfb_console: align fields in gzipped .bmp files
.bmp files contain 32-bit integers aligned at offsets of +2, +6,
et cetera within the bmp_header structure (see include/bmp_layout.h).

Support for gzip-compressed .bmp files is present in the cfb_console
display subsystem by uncompressing them prior to use.

This patch forces the in-memory header to be aligned properly
for these compressed images by extracting them to a 2-byte
offset in the memory returned by malloc. Since malloc will always
return a 4-byte aligned value, this forces the .bmp header
fields to be naturally aligned on 4-byte addresses.

Refer to these files for more details:

73545f75b6 ahci: wait longer for link.
I have observed timeouts on a cubietruck.

The increase to 40ms is completely arbitrary and Works For Me(tm). I
couldn't find a good reference for how long you are supposed to wait,
although googling around it seems like tens of ms rather than single
digits is more common. I don't think there is any harm in waiting a bit
longer.

d57d60cf24 kbuild: move "checkgcc4" to PowerPC archprepare
"checkgcc4" is used only for PowerPC.
Move it to arch/powerpc/config.mk.

To make sure gcc is new enough before beginning build,
run "checkgcc4" during "archprepare".

388b2e520b kbuild: move "checkthumb" to ARM archprepare
"checkthumb" makes sense only for ARM architecture.
Move it to arch/arm/config.mk.

To make sure gcc supports THUMB mode before beginning build,
run "checkthumb" during "archprepare".

58dac32764 powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260
Before this commit, CONFIG_MPC8260 and CONFIG_8260
were used mixed-up.

All boards with mpc8260 cpu defined both of them:
  - CONFIG_MPC8260 was defined in board config headers
      and include/common.h
  - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk

We do not need to have both of them.
This commit keeps only CONFIG_MPC8260.

This commit does:
 - Delete CONFIG_8260 and CONFIG_MPC8260 definition
   in config headers and include/common.h
 - Rename CONFIG_8260 to CONFIG_MPC8260
    in arch/powerpc/cpu/mpc8260/config.mk.
 - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260

cfda6bd2d8 mips: move CONFIG_MIPS{32, 64} definition to config.mk
All mips32 boards define CONFIG_MIPS32 in config headers
except malta boards which define it in boards.cfg.
We can consolidate them by defining it in
arch/mips/cpu/mips32/config.mk.

CONFIG_MIPS64 definition can be moved to
arch/mips/cpu/mips64/config.mk as well.

026f9cf24f kbuild: improve Kbuild speed
Kbuild brought about many advantages for us but a significant
performance regression was reported by Simon Glass.

After some discussions and analysis, it turned out
its main cause is in $(call cc-option,...).

Historically, U-Boot parses all config.mk
(arch/*/config.mk and board/*/config.mk)
every time descending into subdirectories.
That means cc-options are evaluated over and over again.

$(call cc-option,...) is useful but costly.
So we want to evaluate them only in ./Makefile
and spl/Makefile and export compiler flags.

This commit changes the build system as follows:

  - Modify scripts/Makefile.build to not include config.mk
    Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y,
    cppflags-y.

  - Export many variables
    Going forward, Kbuild will not parse config.mk files
    when it descends into subdirectories.
    If we want to set variables in config.mk and use them
    in subdirectories, they must be exported.

    This is the list of variables to get exported:
      PLATFORM_CPPFLAGS
      CPUDIR
      BOARDDIR
      OBJCOPYFLAGS
      LDFLAGS
      LDFLAGS_FINAL
        (used in nand_spl/board/*/*/Makefile)
      CONFIG_STANDALONE_LOAD_ADDR
        (used in examples/standalone/Makefile)
      SYM_PREFIX
        (used in examples/standalone/Makefile)
      RELFLAGS
        (used in examples/standalone/Makefile)

  - Delete CPPFLAGS
    This variable has been replaced with PLATFORM_CPPFLAGS

  - Copy gcclibdir from example/standalone/Makefile
    to arch/sparc/config.mk
    The reference in CONFIG_STANDALONE_LOAD_ADDR must be
    resolved before it is exported.

a0a15b441c config.mk: specify the exact path to standalone linker script
We want to change the build system to include config.mk
only from ./Makefile and spl/Makefile.
We must prepare for that in this commit.

$(src) is a moving target and not handy for our purpose.
We must replace it with a fixed path.

cd2e46cb38 kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC
Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.

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

  #ifdef CONFIG_SPL_BUILD
  # define CONFIG_USE_PRIVATE_LIBGCC
  #endif

to include/configs/tegra-common.h.
