65530a842e tegra20: add clock_set_pllout function
Common practice on Tegra 2 boards is to use the pllp_out4 FO
to generate the ULPI reference clock. For this to work we have
to override the default hardware generated output divider.

This function adds a clean way to do so.

3f44e44f33 tegra20: complete periph_id enum
Most Tegra boards output the ULPI reference clock on pad DEV2.

Complete the periph_id enum so that we are able to enable this

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.

3064f32278 Tegra20: Move some code files to common directories for upcoming Tegra30 patches.
Move files that are going to be common between T20 and T30 into 'tegra-common'
subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any
files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs
and modified for that SoC. The 'common' files should need only minor changes.

Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a
follow-on patch.

Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.

6d365ea0ac tegra20: add USB ULPI init code
This adds the required code to set up a ULPI USB port. It is
mostly a port of the Linux ULPI setup code with some tweaks
added for more correctness, discovered along the way of
debugging this.

To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT
have to be set in the board configuration file.

b823fd9ba5 ARM: prevent misaligned array inits

In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer,
clear the BSS and call board_init_r.  We mark this as weak as some

We provide a gd that we know will be in a usable location, once the BSS
has been cleared to help with this as well.  Finally, we no longer call
relocate_code so remove that from the armv7 version.

Next, both board_init_f and jump_to_image_linux are going to be
inherently arch-specific, so move these versions to arch/arm/lib/spl.c
