On some flash (like Macronix), QE (quad enable) bit is in the same

Intel ICH SPI controller working under descriptor mode).

common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV
CONFIG_SYS_USE_PPCENV is no longer used anywhere. It was used to put
the environment in the special .ppcenv section, but the last
architecture using this section (SuperH) has been changed to not use
it.
Therefore, this commit drops support for CONFIG_SYS_USE_PPCENV
entirely. We only handle two cases:
- We're building the host tool tools/envcrc, in which case the
environment is place with no special section attribute (so it
depends up in .data)
- We're building U-Boot itself, in which case the environnement is
placed in the .text section.

GPT: provide commands to selectively rename partitions
This patch provides support in u-boot for renaming GPT
partitions. The renaming is accomplished via new 'gpt swap'
and 'gpt rename' commands.
The 'swap' mode returns an error if no matching partition names
are found, or if the number of partitions with one name does not equal
the number with the second name. The 'rename' variant always
succeeds as long as a partition with the provided number exists.
Rewriting the partition table has the side-effect that all partitions
end up with "msftdata" flag set. The reason is that partition type
PARTITION_BASIC_DATA_GUID is hard-coded in the gpt_fill_pte()
function. This does not appear to cause any harm.
