Implement support for encrypting/decrypting the environment block
into the tools/env/fw_* tools. The cipher used is AES 128 CBC and
the implementation depends solely on components internal to U-Boot.
To allow building against the internal AES library, the library did
need minor adjustments to not include U-Boot's headers which are not
wanted to be included and define missing types.

pointing to the top of source directory.
(No difference between the two.)

This commit renames SRCTREE to srctree and deletes the

Some NOR flash devices have a small erase block size. For example, the
Micron N25Q512 can erase in 4K blocks. These devices expose a bug in
fw_env.c where flash_write_buf() incorrectly calculates bytes written
and attempts to write past the environment sectors. Luckily, a range
check prevents any real damage, but this does cause fw_setenv to fail
with an error.
This change corrects the write length calculation.
The bug was introduced with commit 56086921 from 2008 and only affects
configurations where the erase block size is smaller than the total
environment data size.

The assumed number of environment sectors (always 1) leads to an
incorrect top_of_range calculation in fw.env.c when a flash device has
an erase block size smaller than the environment data size (number of
environment sectors > 1).
This change updates the default number of environment sectors to at
least cover the size of the environment.
Also corrected a false statement about the number of sectors column in
fw_env.config.

fw_printenv is a program which mostly runs on the target Linux.
Before switching to Kbuild, we needed to set HOSTCC at the
command line like this:
make HOSTCC=<your CC cross-compiler> env
Going forward we can cross compile it by specifying CROSS_COMPILE:
make CROSS_COMPILE=<your cross-compiler prefix> env
This looks more natural.

Before this patch, there was a hard-coded env that was used as default
if the env in flash is detected as invalid. Now this tool (compiled
for a given board) will share the default env with the u-boot for the
board.

Need to define "TEXT_BASE" when building the fw_env tool so that the

This fixes two bugs with comparison of redundant environment flags on
read.
flag0 and flag1 in fw_env_open() were declared signed instead of
unsigned char breaking BOOLEAN mode "== 0xFF" tests and in INCREMENTAL
mode the wrong environment would be chosen where the flag values are
127 and 128 (either way round). With both flags over 128, both signs
flipped and the logic worked by happy accident.
Also there was a logic bug in the INCREMENTAL test (after signedness was
fixed) in the case flag0=0, flag1=255, env 1 would be incorrectly chosen.
Fix both of these.

- use HOSTCFLAGS_NOPED (fw_env.c does not conform to -pedantic).

Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
