15b86c3d6c env_nand.c: print error message and fail gracefully
env_nand.c would crash silently if a malloc() for the environment
buffers failed; make it print an error message and fail gracefully,
i. e. use the default environment then.

18304f7675 env: kill off default_environment_size
The only environment type that uses this variable is spi flash, and that is
only because it is reimplementing the common set_default_env() function.
So fix the spi flash code and kill off the default_environment_size in the
process.

be33b046b5 Remove legacy NAND and disk on chip code.
Legacy NAND had been scheduled for removal.  Any boards that use this
were already not building in the previous release due to an #error.

The disk on chip code in common/cmd_doc.c relies on legacy NAND,
and it has also been removed.  There is newer disk on chip code
in drivers/mtd/nand; someone with access to hardware and sufficient
time and motivation can try to get that working, but for now disk
on chip is not supported.

b74ab73736 nand_spl: read environment early, when booting from NAND using nand_spl
Currently, when booting from NAND using nand_spl, in the beginning the default
environment is used until later in boot process the dynamic environment is read
out. This way environment variables that must be interpreted early, like the
baudrate or "silent", cannot be modified dynamically and remain at their
default values. Fix this problem by reading out main and redundand (if used)
copies of the environment in the nand_spl code.

bdab39d358 rename CONFIG_CMD_ENV to CONFIG_CMD_SAVEENV
The CONFIG_CMD_ENV option controls enablement of the `saveenv` command
rather than a generic "env" command, or anything else related to the
environment.  So, let's make sure the define is named accordingly.

99c2b434d3 NAND: Fix warning due to missing env_ptr casts to u_char * in env_nand.c.
The writeenv() and readenv() calls introduced by the recently added bad block
management for environment variables were missing casts therefore producing
compile time warnings.
While at it fixing some typo in a comment and indentation.

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
