Use a flag instead of a hard-coded macro so that sub-page reads can be
enabled in other cases (such as on-die ecc).
This is the same as a5ff4f102937a3492bca4a9ff0c341d78813414c in Linux

This allows DDR configuration to be deferred to the final U-Boot image,
which is able to make use of SPD data. The SPL itself cannot use SPD due
to code size constraints. It previously used fixed register values for
DDR configuration, and those values did not work on the p2020rdb-pca
board I tested with. It's possible that different revisions of the board
require different settings. Using SPD eliminates that problem.

- Sort by address, and fix column alignment
- Don't label things as localbus that aren't. Instead, put chipselect
info at the end of the description for localbus windows. Note that
NAND/NOR have their chipselects swapped when booting from NAND, and CS2
can be either PMC or VSC7385 depending on hwconfig.
- Shrink NAND to the 32K that's actually mapped in the localbus
- Assign an address and size to L2 SRAM. Remove the similarly named
but unintelligible "L2 SDRAM(REV.)".
- Remove the untrue comment about L1 stack being mapped with TLB0.

Some small SPLs do not use nand_base.c, and a subset of those also
require a special driver. Some SPLs need software ECC but others can't
fit it.
All existing boards that specify CONFIG_SPL_NAND_SUPPORT have these
symbols added to preserve existing behavior.

v2: use positive logic for including bits of NAND, rather than
a MINIMAL symbol that excludes things.

Enable using of new MUSB framework on Beagle.
NOTE! This is not just a change of backend code: top-level behavior
is also changed, we now use USB device port for USB Ethernet instead
of serial.

Backend driver for MUSB OTG controllers found on TI AM35x.
It seems that on AM35X interrupt status registers can be updated
_before_ core registers. As we don't use true interrupts in U-Boot
and poll interrupt status registers instead this can result in
interrupt handler being called with non-updated core registers.
This confuses the code and result in hanged transfers.
Add a small delay in am35x_interrupt as a workaround.

Existing U-Boot musb driver has no support for the new gadget framework
and also seems to have other limitations. As gadget framework is ported
from Linux it seems pretty natural to port musb gadget driver as well.
This driver supports both host and peripheral modes.
This is not a replacement for current musb driver (at least now) as
there are still some consumers of the old UDC interface.
No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be
defined.
Virtual root hub device is not implemented.
Known problems: with no devices connected usb_lowlevel_start() fails.

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.
As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.
Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.
This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

Modify tegra-common-post.h's BOOTCOMMAND definition to use the generic
filesystem command load rather than separate fatload and ext2load.
This removes the need to iterate over supported filesystem types in the
boot command.
This requires editing all board config headers to enable the new
commands. The now-unused commands are left enabled to assue backwards
compatibility with any user scripts. Boards (all from Avionic Design)
which define custom BOOTCOMMAND values are not affected.

TrimSlice's USB1 port has two purposes; it either acts as a device port
hosting Tegra's USB recovery protocol, or acts as a host port connected
to the internal USB->SATA bridge chip, which may in turn be connected to
an SSD or HDD. Add the appropriate device tree and board configuration
options to enable this port as a host port, and route the port to the
SATA bridge using the VBUS GPIO.

The normal alignment is PAGE_SIZE, but if this is defined, we can support
other alignments.
The motivation for this change is to make the display section-aligned on
ARM so that we can easily turn off data caching for the frame buffer region
without resorting to level 2 page tables.

The mx5 lowlevel_init.S contains board-specific code based on the reference
design. Let's keep it since it avoids creating new lowlevel_init files and it
may be used by many boards. But add a config to make it optional in order not to
cause issues on boards not following this part of the reference design.
