To deal with a reoccurring problem properly we need to specify addresses
for the Linux kernel, Flatted Device Tree and ramdisk that obey the
constraints within the kernel's Documentation/arm/Booting file but also
make sure that we relocate things within a valid address range.
It is possible with these addresses to also set fdt_high and initrd_high
to the value of 0xffffffff. We don't do this by default to allow for
the most likely success of people using custom addresses however.

Inside of SPL we only concern ourself with one MMC device, so instead of

We currently limit ourself to 16 characters for the device name to read
the environment from. This is insufficient for /dev/mmcblk0boot1 to

free()ing the buffer.

TI platforms such as OMAP5uevm, PandaBoard, use equivalent
logic to generate fake USB MAC address from device unique DIE ID.
Consolidate this to a generic location such that other TI platforms such
as BeagleBoard-XM can also use the same.

Replace the custom bit manipulation function sr32() by standard I/O
accessors. A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:
6.5.7 Bitwise shift operators
...
If the value of the right operand is negative or is greater
than or equal to the width of the promoted left operand, the
behavior is undefined.

Use smaller fields in the Tegra pinmux structures in order to pack the
data tables into a smaller space. This saves around 1-3KB for the SPL
and around 3-8KB for the main build of U-Boot, depending on the board,
which SoC it uses, and how many pinmux table entries there are.
In order to pack PMUX_FUNC_* into a smaller space, don't hard-code the
values of PMUX_FUNC_RSVD* to values which require 16 bits to store them,
but instead let their values be assigned automatically, so they end up
fitting into 8 bits.

On Tegra30 and later, the PTS (parallel transceiver select) and STS
(serial transceiver select) are part of the HOSTPC1_DEVLC_0 register
rather than PORTSC1_0 register. Since the reset configuration
usually matches the intended configuration, this error did not show

Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)
are prefixed with PMUX_, and functions prefixed with pinmux_.
* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
compiles. A separate per-SoC change will be made immediately following,

Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the
duplication by creating pinmux-common.c for all the identical code.
This leaves:
* arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of
the various pins/pin groups, drive groups, and mux functions.
* arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table
stating which pin groups support which mux functions.
The code in pinmux-common.c is semantically identical to that in the
various original pinmux.c, but had some consistency and cleanup fixes
applied during migration.
I removed the definition of struct pmux_tri_ctlr, since this is different
between SoCs (especially Tegra20 vs all others), and it's much simpler to
deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c,
and warmboot_avp.c needed updates due to this, since they previously
hijacked this struct to encode the location of some non-pinmux registers.
Now, that code simply calculates these register addresses directly using
simple and obvious math. I like this method better irrespective of the
pinmux code cleanup anyway.

Tegra's "APB misc" register region contains various miscellaneous
registers and the Tegra pinmux registers. Some code that touches the
misc registers currently uses struct pmux_tri_ctlr, which is intended to
be a definition of pinmux registers, rather than struct apb_misc_pp_ctrl,
which is intended to be a definition of the miscellaneous registers.
Convert all such code to use struct apb_misc_pp_ctrl, since struct
pmux_tri_ctlr goes away in the next patch.
This requires adding a missing field definition to struct
apb_misc_pp_ctrl, and moving the header into a more common location.

For consistency with other SoCs, modify Tegra20's enum pmux_func to:
* Remove PMUX_FUNC values that aren't real
* Use the same PMUX_FUNC_RSVD[1-4] values, and ensure (RSVD1 & 3)==0;
this will be assumed by pinmux_set_func() in a future patch.
Unfortunately, PMUX_FUNC_RSVD is still used in the pin macros. Use a
private define inside the driver to prevent this from causing compilaton
errors. This will be cleaned up when the pin tables are re-written in a
later patch in this series.
