72573543b5 ARM: tegra: enable 8-bit SD slots in board files
Harmony contains an SD slot with all 8 bits routed. This allows plugging
in an eMMC-chip-in-SD-form-factor.

Seaboard/Springbank/Ventana/AC100 all have an eMMC chip with all 8 bits
hooked up.

Now that the U-Boot eMMC code fully supports 8-bit operation, initialize
those ports as 8-bit instead of 4-bit to improve performance.

Whistler was already registering its ports as 8-bit.

TrimSlice doesn't have any 8-bit ports.

I don't have any Avionic Design boards nor the Colibri board to test with.

a2ab6b7d32 ARM: tegra: don't request GPIO from Seaboard's SPL
Seaboard has a GPIO that switches an external mux between Tegra's debug
UART and SPI flash. This is initialized from the SPL so that SPL debug
output can be seen. Simplify the code that does this, and don't actually
request the GPIO in the SPL; just program it. This saves ~4.5K from the
size of the SPL, mostly BSS due to the large gpio_names[] table that is
no longer required. This makes Seaboard's SPL fit within the current max
size.

da1f735272 ARM: tegra: select between Seaboard/Ventana at compile time
Seaboard and Ventana are very similar boards, and so share the seaboard.c
board file. The one difference needed so far is detected at run-time by
calling machine_is_ventana(). This bloats the Ventana build with code
that is never used. Switch to detecting Ventana at compile time to remove
bloat. This shaves ~5K off the SPL size on Ventana, and makes the SPL fit
within the max size.

56f42f85f5 ARM: tegra: Whistler: remove unused USB alias
Port USB1 on Whistler is intended as a device port for USB recovery.
Whistler's DT currently contains an alias for this USB port, even though
Whistler's config doesn't enable multiple USB controllers, so the alias
is unused. Remove the unused alias for consistency for now. Similar,
explicitly disable the port in the device tree too.

73286d8729 tegra: move common features to a common makefile
For Non-Nvidia boards to include newly added features (like emc clock
scaling) it would be necessary to add each feature to their own board
Makefile. This is because currently the top Makefile automaticly includes
these features only for Nvidia boards.

This patch adds a simple Makefile include so all new features become
available for non-Nvidia board vendors.

0cd10c7abf tegra20: rework UART GPIO handling
Rename board provided gpio_config_uart() to
gpio_early_init_uart() as it does the same thing as the equally
called function provided by the uart-switch code. This allows
to simply call this function in early board init whether or not
we are building with CONFIG_UART_SWITCH defined.

Also provide a weak symbol for this function, to avoid the
need to provide this function for boards that don't need any
fixup.

This patch supersedes the earlier posted
"tegra: convert gpio_config_uart to weak symbol".
Build tested with MAKEALL -s tegra20

150c24936b Tegra20: Move some include files to arch-tegra for sharing with Tegra30
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.

All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

cf46cdebdd ARM: tegra: fix Ventana standalone build
Ventana always pulls in files from the Seaboard directory, so needs to
mkdir $(obj)../seaboard unconditionally. This fixes:

git clean -f -d -x
./MAKEALL ventana

"MAKEALL -s tegra20" passes without this change, because Seaboard
happens to be built before Ventana, and hence the directory has already
been created.

I believe the mkdir is only needed for out-of-tree builds, since the
seaboard directory is part of the source tree. However, since we always
build an SPL for Tegra now, which I believe is effectively an out-of-tree
build, we will always need this at some time. The overhead of just
uncondtionally executing the mkdir is minimal, and simplifies the
Makefile, since we don't need to code up the exact minimal condition to
execute the mkdir.
