* Avoid flicker on the TRAB's VFD by synchronizing the enable with

Browse Source 
the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100
  boards, version 153 for Rev. 200 boards).

* Patch by Vladimir Gurevich, 12 Mar 2003:
  Fix relocation problem of statically initialized string pointers
  in common/cmd_pci.c

* Patch by Kai-Uwe Blm, 12 Mar 2003:
  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by
    writing beyond the block boundaries.
  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.

If you boot from a partition which is mounted writable, and you
update your boot environment by replacing single files on that
partition, you should also define CFG_JFFS2_SORT_FRAGMENTS. Scanning
the JFFS2 filesystem takes *much* longer with this feature, though.
Sorting is done while inserting into the fragment list, which is
more or less a bubble sort. That algorithm is known to be O(n^2),
thus you should really consider if you can avoid it!
There is two ways for JFFS2 to find the disk. The default way uses
the flash_info structure to find the start of a JFFS2 disk (called

* Bugfixing by Kai-Uwe Bloem <kai-uwe.bloem@auerswald.de>, (C) Mar/2003
*
* - overhaul of the memory management. Removed much of the "paper-bagging"
* in that part of the code, fixed several bugs, now frees memory when
* partition is changed.
* It's still ugly :-(
* - fixed a bug in jffs2_1pass_read_inode where the file length calculation
* was incorrect. Removed a bit of the paper-bagging as well.
* - removed double crc calculation for fragment headers in jffs2_private.h
* for speedup.
* - scan_empty rewritten in a more "standard" manner (non-paperbag, that is).
* - spinning wheel now spins depending on how much memory has been scanned
* - lots of small changes all over the place to "improve" readability.
* - implemented fragment sorting to ensure that the newest data is copied
* if there are multiple copies of fragments for a certain file offset.
*
* The fragment sorting feature must be enabled by CFG_JFFS2_SORT_FRAGMENTS.
* Sorting is done while adding fragments to the lists, which is more or less a
* bubble sort. This takes a lot of time, and is most probably not an issue if
* the boot filesystem is always mounted readonly.
*
* You should define it if the boot filesystem is mounted writable, and updates
* to the boot files are done by copying files to that filesystem.
*
*
* There's a big issue left: endianess is completely ignored in this code. Duh!
*
*
* You still should have paper bags at hand :-(. The code lacks more or less
* any comment, and is still arcane and difficult to read in places. As this
* is incompatible with any new code from the jffs2 maintainers anyway, it
* should probably be dumped and replaced by something like jffs2reader!

/*
* IO definitions. We define {out,in,outs,ins}[bwl] if __io is defined
* by the machine. Otherwise, these definitions are left for the machine
* specific header files to pick up.
* IO port access primitives
* -------------------------
*
* The ARM doesn't have special IO access instructions; all IO is memory
* mapped. Note that these are defined to perform little endian accesses
* only. Their primary purpose is to access PCI and ISA peripherals.
*
* Note that for a big endian machine, this implies that the following
* big endian mode connectivity is in place, as described by numerious
* ARM documents:
*
* PCI: D0-D7 D8-D15 D16-D23 D24-D31
* ARM: D24-D31 D16-D23 D8-D15 D0-D7
*
* The machine specific io.h include defines __io to translate an "IO"
* address to a memory address.
*
* Note that we prevent GCC re-ordering or caching values in expressions
* by introducing sequence points into the in*() definitions. Note that
* __raw_* do not guarantee this behaviour.
*
* The {in,out}[bwl] macros are for emulating x86-style PCI/ISA IO space.
