The PMIC framework has been extended to support multiple instances of
the variety of devices responsible for power management.
This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB
Interface Circuit).
Power related includes have been moved to ./include/power directory.
This is a first of a series of patches - in the future "pmic" will be
replaced with "power".
Two important issues:
1. The PMIC needs to be initialized just after malloc is configured
2. It uses list to hold information about available PMIC devices

Since the pmic_reg_read is the u32 value, the order in which bytes

Moreover calls to [leXX|beXX]_to_cpu have been added to support
little and big endian SoCs.

u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives. Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h. They come with 'const' added for some swab functions, so
fix those up, too:
include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]
Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).
We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:
macb.c:54:0: warning: "barrier" redefined [enabled by default]
In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)). This fixes
arch/powerpc/lib/bootm.c:
bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token
powerpc sparse builds yield:
include/common.h:356:22: error: marked inline, but without a definition
the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was

When the generic filesystem load command "fsload" was written, I felt
that "load" was too generic of a name for it, since many other similar
commands already existed. However, it turns out that there is already
an "fsload" command, so that name cannot be used. Rename the new
"fsload" to plain "load" to avoid the conflict. At least anyone who's
used a Basic interpreter should feel familiar with the name!

Commit 045fa1e "fs: add filesystem switch libary, implement ls and
fsload commands" unified the implementation of fatload and ext*load
with the new command fsload. However, this altered the interpretation
of command-line numbers from always being base-16, to requiring a "0x"
prefix for base-16 numbers. Enhance do_fsload() to allow commands to
specify which base to use.
Use base 0, thus requiring a "0x" prefix for the new fsload command.
This feels much cleaner than assuming base 16.
Use base 16 for the pre-existing fatload and ext*load to prevent a
change in behaviour.
Use base 16 exclusively for the loadaddr environment variable, since
that variable is interpreted in multiple places, so we don't want the
behaviour to change.
Update command help text to make it clear where numbers are assumed to
be hex, and where an explicit "0x" prefix is required.

In the structure returned by the ATA identify device command, there are two
fields which describe the device capacity. One is a 32 bit data type which
reports the number of sectors as a 28 bit LBA, and the other is a 64 bit data
type which is for a 48 bit LBA. If the device doesn't support 48 bit LBAs,
the small value is the only value with the correct size. If it supports more,
if the number of sectors is small enough to fit into 28 bits, both fields
reflect the correct value. If it's too large, the smaller field has 28 bits of
1s, 0xfffffff, and the other field has the correct value.
The AHCI driver is implemented by attaching to the generic SCSI code and
translating on the fly between SCSI binary data structures and AHCI data
structures. It responds to requests to execute specific SCSI commands by
executing the equivalent AHCI commands and then crafting a response which
matches what a SCSI disk would send.
The AHCI driver now considers both fields and chooses the correct one when
implementing both the SCSI READ CAPACITY (10) and READ CAPACITY (16) commands.

CONFIG_ENV_VARS_UBOOT_CONFIG creates environment variables indicating
which configuration U-Boot was built for. Some U-Boot binaries run on
multiple boards, and hence this information may not uniquley describe
the HW that U-Boot is actually running on. Another patch introduces
environment variable board_name to represent that. In order to avoid
scripts having to check $board_name, use it if set, and then fall back
to using $board, make CONFIG_ENV_VARS_UBOOT_CONFIG also set a default
value for board_name, so that variable is always available.

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.

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.

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.

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.

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.

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.

This patch remove the env saving in NAND as so far the
NAND driver is not ported to the M54418TWR platform.

These boards have long reached EOL, and there has been no indication
of any active users of such hardware for years. Get rid of the dead
weight.
