tegra20: rename tegra2 -> tegra20

2012-09-01T12:58:21+00:00

This is make naming consistent with the kernel and devicetree and in
preparation of pulling out the common tegra20 code.

tegra: add enterrcm command

2012-07-09T20:44:33+00:00

Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.

This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

tegra: usb: fix wrong error check

2012-07-09T20:44:33+00:00

loop_count runs down from 10000, so the correct condition to error out
is ==0.

This is needed as a prerequisite for Tegra USB ULPI support
within U-Boot.

arm: Tegra: Use ODMDATA from BCT in IRAM

2012-07-07T12:07:21+00:00

Walk the BIT and BCT to find the ODMDATA word in the
CustomerData field and put it into Scratch20 reg for
use by kernel, etc.

Built all Tegra builds OK; Booted on Seaboard and saw
ODMDATA in PMC scratch20 was the same as the value in my
burn-u-boot.sh file (0x300D8011). NOTE: All flash utilities
will have to specify the odmdata (nvflash --odmdata n) on
the command line or via a cfg file, or built in to their
BCT.

tegra: override compiler flags for low level init code

2012-07-07T12:07:19+00:00

Override -march setting for tegra to -march=armv4t for files that are
necessary for low level init on tegra.

The recent change to use -march=armv7-a for armv7 caused a regression
on tegra because tegra starts boot on a arm7tdmi processor before
transferring control to the cortex-a9.  While still executing on the
arm7tdmi there are calls to getenv_ulong() and memset() that cause an
illegal instruction exception if compiled for armv7.

tegra: Correct PLL access in ap20.c and clock.c

2012-07-07T12:07:19+00:00

Correct this warning seen by Albert:

ap20.c:44:18: warning: array subscript is above array bounds

There is a subtle bug here which currently causes no errors, but might
in future if people use PCI or the 32KHz clock. So take the opportunity
to correct the logic now.
