We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.

The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().

... rather than open-coding the register accesses.

However, gpio_request() typically stores the "label" parameter in a global
data structure. This causes problems when called from gpio_config_uart(),
since the code is running before relocation. To solve this, pass a NULL
string to gpio_request(), and modify gpio_request() not to touch the string
if it's NULL.

Ventana is a board which is very similar to Seaboard. Support it by
re-using board/nvidia/seaboard/seaboard.c with minor run-time conditionals.

v5: Makefile: Use cmd_link_o_target, remove unused clean/distclean targets.
v6: Make gpio_config_uart_seaboard() static.
v7: Add MAINTAINERS entry for Ventana. Tom Warren doesn't have Ventana, so
    he asked me to add myself for this board.

Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and
modify that function to perform all required GPIO initialization. This
removes the need for board files to perform these operations.

Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which
GPIOs to use.

Update affected call-sites in seaboard.c and harmony.c. Note that this
change should make all SD ports work on Harmony, since the required GPIO
setup is now being performed.

v4: Fix prototype of tegra2_mmc_init() in board.h to match driver change.

For Seaboard, this is mostly a cut/paste of board_mmc_init() and
pin_mux_mmc() into seaboard.c; pin_mux_mmc() was modified to add some
missing pinmux_tristate_disable calls for the GPIOs.

For Harmony, those functions were modified to configure SDMMC2 (index 2)
instead of SDMMC3 (index 1), since that's what is present on the board.

However, harmony.c is still missing the required GPIO setup, so neither
port is likely to function correctly yet.  This will be fixed in the next
change.

v4: Include board.h to prototype tegra2_mmc_init().

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.

Standard Debian powerpc and powerpcspe systems only include hard-float
libgcc in their native compilers, which causes scary build warnings when
building U-Boot.

Debian and other PowerPC-supporting distributions used to provide libgcc
and other libraries in a "nof" (soft-float) form in the "multilib"
packages.  As they were completely unused by the distribution and
therefore tended to be very buggy it was decided to save some time on
the part of the maintainers and build-servers by removing them.

Admittedly, right now the linker warnings do not indicate any problems,
as the included routines do not use any floating point at all.

The concern is that if floating-point code were ever added it might
cause hard-float code to be unexpectedly included in U-Boot without
generating a hard error.  This would cause unexplained crashes or
indeterminate results at runtime.

The easiest way to resolve this is to borrow the routines that U-Boot
needs from the Linux kernel, which has the same issue.

Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3().
They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5,
commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+.

The Makefile framework was copied from the U-Boot ARM port.

  video: cfb_console: Make the software cursor non-destructive

TPM (Trusted Platform Module) is an integrated circuit and
software platform that provides computer manufacturers with the
core components of a subsystem used to assure authenticity,
integrity and confidentiality.

This driver supports version 1.2 of the TCG (Trusted Computing
Group) specifications.

The TCG specification defines several so called localities in a
TPM chip, to be controlled by different software layers. When
used on a typical x86 platform during the firmware phase, only
locality 0 can be accessed by the CPU, so this driver even while
supporting the locality concept presumes that only locality zero
is used.

This implementation is loosely based on the article "Writing a
TPM Device Driver" published on http://ptgmedia.pearsoncmg.com

Compiling this driver with DEBUG defined will generate trace of
all accesses to TMP registers.

This driver has been tested and is being used in three different
functional ChromeOS machines (Pinetrail and Sandy Bridge Intel
chipsets) all using the same Infineon SLB 9635 TT 1.2 device.

A u-boot cli command allowing access to the TPM was also
implemented and is being submitted as a second patch.
