powerpc: Minimal private libgcc to build on Debian
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.

Introduce generic TPM support in u-boot
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.

Added noop implementation for dcache operations that will buzz
about missing real implementation and disable the dcache.
This fixes compilation of DaVinci EMAC driver on arm926ejs.

davinci_emac: use internal addresses in buffer descriptors
On AM35xx CPPI RAM had different addresses when accessed from the CPU
and from the EMAC. We need to account this to deal with the buffer
descriptors correctly.

davinci_emac: move arch-independent defines to separate header
DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs
also. This patch moves common defines from arch-davinci/emac_defs.h to
drivers/net/davinci_emac.h
DaVinci specific PHY drivers hacked to include the new header. We might
want to switch to phylib in future.

omap4: fix IO setting
The value from TRIM is not working for some 4430 silicons.
So, override with hw team recommended value. However, for
4460 TRIM value shall be used as long as the part is trimmed
This fixes boot problem on some OMAP4430 ES2.0 Panda boards
out there.

omap4+: streamline CONFIG_SYS_TEXT_BASE and other SDRAM addresses
Change the CONFIG_SYS_TEXT_BASE and the addresses of SDRAM
buffers used by SPL(heap and BSS) keeping in mind the
following requirements:
1. Make sure that SPL's heap and BSS doesn't come in the way
of Linux kernel, which is typically loaded at 0x80008000. This
will be important when SPL directly loads kernel.
2. Align the CONFIG_SYS_TEXT_BASE between TI internal
U-Boot and mainline U-Boot. This avoids a lot of confusion
and allows for the inter-operability of x-loader, SPL,
internal U-Boot, mainline U-Boot etc. The internal U-Boot's
address can not be changed to that of mainline U-Boot
as internal U-Boot doesn't have relocation and 0x80100000
used by mainline U-Boot will clash with kernel
3. Assume only a minimum amount of memory that may be available
on any practical OMAP4/5 board in future too. We are assuming
a minimum of 128 MB of memory

omap4460: fix TPS initialization
TPS power IC is controlled using a GPIO (gpio_wk7).
This GPIO should be maintained at logic 1 always. As
such an internal pull-up on this pin will do the job,
driving the GPIO outuput is not needed. This will avoid
the need of using GPIO library in SPL and also may
save some power.

armv7: disable L2 cache in cleanup_before_linux()
We were not disabling external caches before jumping
to kernel. We were flushing all caches including
external caches and disabling caches globally in
CP15 System Control register. Apparently this is not
enough.
The bootstrap loader in Linux kernel that does decompression
enables data-caches again, flush them after use and disable
them before jumping to kernel proper. However, it's not aware
of the external caches.
Since we have left external cache enabled, external cache will
get used once caches are enabled globally, but it's not flushed
because decompressor is not aware of external caches. When it
jumps to kernel with caches disabled globally, we have stale
data in the external cache and a coherency problem.
This was breaking the boot for OMAP4 with latest mainline
kernel. The solution is to disable external caches in
cleanup_before_linux(). With this fix kernel is booting again.
