Commit 52a7c98a17 "tegra-common: increase malloc pool len by dfu mmc
file buffer size" updated the definition of CONFIG_SYS_MALLOC_LEN for
Tegra to take account of the DFU buffer size. However, this change had
no effect, since typical Tegra board config headers don't set the DFU-
related defines until after tegra-common.h is included. Fix this by
moving the affected conditional code to tegra-common-post.h, which is
included last. Also move the definition of SYS_NONCACHED_MEMORY since
it's a related and adjacent definition.
Fix the condition to test for the DFU feature, rather than specifically
MMC DFU support, so it applies in all cases.

Represent all available RAM in either one or two banks. The first bank
describes any RAM below 4GB. The second bank describes any RAM above 4GB.
This split is driven by the following requirements:
- The NVIDIA L4T kernel requires separate entries in the DT /memory/reg
property for memory below and above the 4GB boundary. The layout of that
DT property is directly driven by the entries in the U-Boot bank array.
- On systems with RAM beyond a physical address of 4GB, the potential
existence of a carve-out at the end of RAM below 4GB can only be
represented using multiple banks, since usable RAM is not contiguous.
While making this change, add a lot more comments re: how and why RAM is
represented in banks, and implement a few more "semantic" functions that
define (and perhaps later detect at run-time) the size of any carve-out.

Add option to set shell prompt string from menuconfig and migrate
boards globally.
The migration is done as follows:
- Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the
entry moved to their defconfig files.
- Boards that defined some kind of #ifdef logic which selects the
CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT
right before the #ifdef logic and were left alone.
- This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus
CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h
files. This results in a streamlined default value across platforms, and
includes the following files: spear-common, sunxi-common, mv-common,
ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common.
- Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were
not updated in their respective defconfig files under the assumption that
since they did not explicitly define a value, they're fine with whatever
the default is.
- On the other hand, boards that relied on a value defined in some
<boards>_common.h file such as woodburn_common, rpi-common,
bur_am335x_common, ls2085a_common, siemens_am33x_common, and
omap3_evm_common, had their values moved to the respective defconfig files.
- The define V_PROMPT was removed, since it is not used anywhere except for
assigning a value for CONFIG_SYS_PROMPT.

This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

1) It isn't documented in README. The same is true for a lot of similar

2) It doesn't represent MAX_DEVICE but rather NUM_DEVICES, since the
valid values are 0..n-1 not 0..n.

Before this commit, USE_PRIVATE_LIBGCC was defined in

We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.
By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)
Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.
It means Tegra enables PRIVATE_LIBGCC only for SPL.

# define CONFIG_USE_PRIVATE_LIBGCC
#endif
