dfcd7f2160 Redundant Environment: protect full sector size
Several boards used different ways to specify the size of the
protected area when enabling flash write protection for the sectors
holding the environment variables: some used CONFIG_ENV_SIZE and
CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even
a mix of both for the "normal" and the "redundant" areas.

Normally, this makes no difference at all. However, things are
different when you have to deal with boards that can come with
different types of flash chips, which may have different sector
sizes.

Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the
biggest sector size, which may include several sectors on boards using
the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE
or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the
case that only the first of these sectors get protected, while the
following ones aren't.

This is no real problem, but it can be confusing for the user -
especially on boards that use CONFIG_ENV_SECT_SIZE to protect the
"normal" areas, while using CONFIG_ENV_SIZE_REDUND for the
"redundant" area.

To avoid such inconsistencies, I changed all sucn boards that I found
to consistently use CONFIG_ENV_SECT_SIZE for protection. This should
not cause any functional changes to the code.

9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

d39b574158 board/[j-z]*: Remove lingering references to CFG_CMD_* symbols.
Fixed some broken instances of "#ifdef CMD_CFG_IDE" too.
Those always evaluated TRUE, and thus were always compiled
even when IDE really wasn't defined/wanted.

9107ebe0d3 board/[k-z]*: Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).
This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

787fa15860 Fix auto_update for MCC200 board.
The invocation of do_auto_update() is moved to the end of the
misc_init_r() function, after the flash mappings have been
initialized. Please find attached a patch that implements that
change.

Also correct the decoding of the keypad status. With this update, the
key that will trigger the update is Column 2, Row 2.
