Rename this function for consistency with env_set().

We are now using an env_ prefix for environment functions. Rename setenv()
for consistency. Also add function comments in common.h.Suggested-by: Wolfgang Denk

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.Also expand the help for the 'nowhere' option and move it to the top since
it is the default.Signed-off-by: Simon Glass

When the EEPROM is first read its contents are stored in memory as a
cache to avoid further I2C operations. To determine if the EEPROM was
previously read the easiest way is to check the memory to see if the
EEPROM's magic header value is set. Create a new function that can
determine if the EEPROM was previously read or not without having to
perform a I2C transaction.Signed-off-by: Franklin S Cooper Jr

In some situations the EEPROM used for board detection may not be
programmed or simply programmed incorrectly. Therefore, it may be
necessary to "simulate" reading the contents of the EEPROM to set
appropriate variables used in the board detection code.This may also be helpful in certain boot modes where doing i2c reads
may be costly and the config supports running only a specific board.Signed-off-by: Nishanth Menon

Currently these (board agnostic) commands cannot be selected using
menuconfig and friends. Fix this the obvious way. As part of this,
don't muddle the meaning of CONFIG_HASH_VERIFY to mean both 'hash -v'
and "we have a hashing command" as this makes the Kconfig logic odd.Signed-off-by: Daniel Thompson

In non DM I2C read operations the address length passed in during a read
operation will be used automatically. However, in DM I2C the address length
is set to a default value of one which causes problems when trying to
perform a read with a differing alen. Therefore, before the first read in a
series of read operations set the alen to the correct value.Signed-off-by: Franklin S Cooper Jr

Reading from the I2C EEPROM used typically requires using an address length
of 2. However, when using DM for I2C the default address length used is 1.
To fix this introduce a new function that allows the address length to be
changed. The logic to do so was copied from cmd/i2c.c.Signed-off-by: Franklin S Cooper Jr

Instead of defining command options in every defconfig,
define a common Kconfig symbol that consolidates all command
options that are supported by any TI platform. Also use imply

Current logic for query of revision, board_name, config returns
NULL. Users of these functions do a direct strncmp to compare.
Unfortunately, as per conventions require two valid strings to compare
against and the current implementation causes a crash when compared
with NULL.We'd still like to maintain the simplistic usage of these APIs instead
of redundant if (string) res=strncmp(fn(),"cmp",n); flowing all over
the place.Hence, since the version, name and config is already pre-initialized
with empty string, just dont check for invalid header in the first
place and return the empty string to the caller.Reported-by: Brad Griffis

DRA7 EVM revH and later EVMs have EEPROM populated that can contain board
description information such as name, revision, DDR definition, etc. Adding
support for this EEPROM format.Acked-by: Nishanth Menon
Reviewed-by: Tom Rini
Signed-off-by: Lokesh Vutla -
Several TI EVMs have EEPROM that can contain board description information
such as revision, DDR definition, serial number, etc. In just about all
cases, these EEPROM are on the I2C bus and provides us the opportunity
to centralize the generic operations involved.The on-board EEPROM on the BeagleBone Black, BeagleBone, AM335x EVM,
AM43x GP EVM, AM57xx-evm, BeagleBoard-X15 share the same format.
However, DRA-7* EVMs, OMAP4SDP use a modified format.We hence introduce logic which is generic between these platforms
without enforcing any specific format. This allows the boards to use the
relevant format for operations that they might choose.This module will compile for all TI SoC based boards when
CONFIG_TI_I2C_BOARD_DETECT is enabled to have optimal build times for
platforms that require this support.It is important to note that this logic is fundamental to the board
configuration process such as DDR configuration which is needed in
SPL, hence cannot be part of the standard u-boot driver model (which
is available later in the process). Hence, to aid efficiency, the
eeprom contents are copied over to SRAM scratchpad memory area at the
first invocation to retrieve data.To prevent churn with cases such as DRA7, where eeprom format maybe
incompatible, we introduce a generic common format in eeprom which
is made available over accessor functions for usage.Special handling for BBG1 EEPROM had to be introduced thanks to the
weird eeprom rev contents used.The follow on patches introduce the use of this library for AM335x,
AM437x, and AM57xx.Signed-off-by: Lokesh Vutla
