As we moved data_crc() invocation from jffs2_1pass_build_lists() to
jffs2_1pass_read_inode() data_crc is going to be calculated on each
inode access. This patch adds caching of data_crc() results. There
is no significant improvement in speed (because of flash access
caching added in previous patch I think, crc in RAM is really fast)
but this patch impacts memory usage -- every b_node structure uses
12 bytes instead of 8.

This patch adds support for reading fs information from summary
node instead of scanning full eraseblock.

With this patch JFFS2 code allocates memory buffer of max_totlen size
(size of the largest node, calculated during scan time) and uses it to
store entire node. Speeds up loading. If malloc fails we use old ways
to do things.

Rewrites jffs2_1pass_build_lists() function in style of Linux's
jffs2_scan_medium() and jffs2_scan_eraseblock().
This includes:
- Caching flash acceses
- Smart dealing with free space

We need to update i_version inside cycle to find really latest version
inside jffs2_1pass_list_inodes(). With that fixed we can use isize inside
dump_inode() instead of calling expensive jffs2_1pass_read_inode().

The nand_info array is declared as extern in several .c files.
Those days, nand.h contains a reference to the array, so there is
no need to declare it elsewhere.

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.

This change is in preparation for condtitionial compile support in the
build system. By spliting them all into seperate lines now, subsequent
patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will
be less invasive and easier to review

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.

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)

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.

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
implemented for these boards.

Old, obsolete and duplicated code was cleaned up and replace by the
new partitioning method. There are two possible approaches now:
* define a single, static partition
* use mtdparts command line option and dynamic partitioning
Default is static partitioning.
Using external watchdog for KUP4 boards in mpc8xx/cpu.c;
load_sernum_ethaddr() for KUP4 boards in lib_ppc/board.c;
various changes to KUP4 board specific files
* Fixes for SL811 USB controller:
- implement workaround for broken memory stick
- improve error handling
* Increase packet send timeout to 10 ms in cpu/mpc8xx/scc.c to better
cope with congested networks.

Fix VSC/CIS 8201 phy descrambler interoperability timing due to
errata from Vitesse Semiconductor.
JFFS2 speed enhancements:
- repair header CRC calculation in jffs2_1pass.c
- add eraseblock size to the partition information to skip empty
eraseblocks if we find more then 4k of free space.
- The JFFS2 scanner is now fast enough to remove the spinning wheel
so #ifdef-ed out.
- add watchdog calls in long running loops
