045fa1e114 fs: add filesystem switch libary, implement ls and fsload commands
Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load},
and transparently handle either file-system. This scheme could easily be
extended to other filesystem types; I only didn't do it for zfs because
I don't have any filesystems of that type to test with.

Replace the implementation of {fat,ext[24]}{ls,load} with this new code
too.

03e2ecf6b8 fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}
This makes the FAT and ext4 filesystem implementations build if
CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on
whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the
filesystems to be built separately from the filesystem-specific commands
that use them. This paves the way for the creation of filesystem-generic
commands that used the filesystems, without requiring the filesystem-
specific commands.

Minor documentation changes are made for this change.

The new config options are automatically selected by the old config
options to retain backwards-compatibility.

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.

644a69ec85 ARM: tegra: derive CONFIG_SPL_MAX_SIZE instead of hard-coding it
For Tegra, the SPL and main U-Boot are concatenated together to form a
single memory image. Hence, the maximum SPL size is the different in
TEXT_BASE for SPL and main U-Boot. Instead of manually calculating
SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if
one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform
the calculation automatically.

2b7818d49f ARM: enhance u-boot.lds to detect over-sized SPL
Add an ASSERT() to u-boot.lds to detect an SPL that doesn't fit within
SPL_TEXT_BASE..SPL_MAX_SIZE.

Different .lds files implement this check in two possible ways:
1) An ASSERT() like this
2) Defining a MEMORY region of size SPL_MAX_SIZE, and re-directing all
   linker output into that region. Since u-boot.lds is used for both
   SPL and main U-Boot, this would entail only sometimes defining a
   MEMORY region, and only sometimes performing that redirection, and
   hence option (1) was deemed much simpler, and hence implemented.

Note that this causes build failures at least for NVIDIA Tegra Seaboard
and Ventana. However, these are legitimate; the SPL doesn't fit within
the required space, and this does cause runtime issues.

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

e73c7cdd1e ARM: tegra: Seaboard: enable multiple USB ports
The device tree already contains the required configuration for both the
USB1 and USB3 ports. Enable the required configuration options to enable
both these ports, which in turn allows the USB1 port to be used.

Note that on a true Seaboard, this port is typically used as a device
port hosting Tegra's USB recovery protocol. However, on the Springbank
derivative, this port is the only external USB port, so we enable it as
a host port so that USB peripherals may be used. Enabling this port in
U-Boot as a host port doesn't prevent the port from reverting to a
device port when the CPU is reset into recovery mode.

938176a482 ARM: tegra: use standard variables to define load addresses
Currently, Tegra's default environment uses non-standard variables to define
where boot scripts should load the kernel, FDT, and initrd. This change both
changes the variable names to match those described in U-Boot's README, and
shuffles their values around a little so that the values make a little more
sense; see comments in the patch for rationale behind the values chosen.

Note that this patch does remove the old non-standard variable "fdt_load" from
the default environment, so this patch requires people to change their boot
scripts.

7f1b767aea ARM: tegra: define CONFIG_SYS_BOOTMAPSZ
This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
   since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.

c3f8318f33 am335x_evm: Enable use of UART{1,2,3,4,5}
Add targets of am335x_evm_uart{1,2,3,4,5} to have serial input/output on
UART{1,2,3,4,5} for use with the Beaglebone RS232 cape, am335x_evm
daughterboard, and other custom configurations.

Modify target for am335x_evm to include SERIAL1 and CONS_INDEX=1
options in order to clarify UART selection requirements.
