Hi Wolfgang
those patches are for add xburst jz4740 and Ben NanoNote(named qi_lb60) to U-Boot
some info about xburst jz4740:
the xburst jz4740 is recently added to linux 2.6.36
and it's support the device Ben NanoNote out of box,
this xburst jz4740 cpu have one feature is Boot From USB, there is a
small rom in jz4740, but LOW some PIN, the cpu will boot to this small
rom, then init cpu and USB module, then we can send 8KB bin file to
the cpu by USB(by using 'xbboot' or 'usbboot'[1]).
which means if your bootloader is borken,(the first few KBs in NAND)
you can always boot the device from usb, then reflash the nand.
in OpenMoko FreeRunner, there are NOR and NAND. when people broken the
nand bootloader, it's must boot from NOR, reflash the bootloader back
when people broken the NAND and NOR, he(she) must reflash by using JTAG
but in Ben NanoNote, we just need boot from usb. flash the nand again :)
BTW:there are a lot of PMP, Audio device in China use the Xburst cpu,
but I think they are all base on u-boot 1.1.6. by working on
Ben NanoNote (http://en.qi-hardware.com) one year, we try to
update the u-boot to last version and send it to upstream. :)

====
FIXED in [PATCH v3]
1. describe what Jz4740 SoC
2. remove the ENDIANNESS in config.mk
3. don't breaks the 80-charcter-wide rule
4. get rid of #if 0
5. use proper I/O accessors to access registers.
6. remove C++ comments, cleanup code style.
FIXED in [PATCH v4]
1. add Entry to MAINTAINERS and boards.cfg
2. add ben nanonote(qi_lb60) to Makefile
3. tested with CROSS_COMPILE=mips_4KCle- ./MAKEALL mips_el
FIXED in [PATCH v5]
1. remove nand_spl/nand_boot_jz4740.c
2. some cleanup
====
Xiangfu Liu (8):
those files are jz4740 base files
this is jz4740 head file
jz4740 nand spl files
jz4740 nand driver
add Ben NanoNote board
add entry to MAINTAINERS and boards.cfg
modify files for ben nanonote board
add software usbboot

Very useful comments, so such info should also be put into patch
description of the relevant changes; Jz4740 SoC overview and about USB
boot, respectively.

Having a quick glance, v5 still has issues (e.g. it gets split into
8 patches in an improper way). I'll have a closer look later.
By the way, I've uploaded xl/jz4740-ben-nanonote-v5 branch (and older
v2/v3/v4 branches as well) to make reviews easier for involved people.

There is no description of the changes in this version of the patch.
The notes in the introductory message are _not_ sufficient, please see

We do not allow CamelCase identifiers in U-Boot. Please fix globally.

No space after the paren; please fix globally.

Please do not use base + offset notation. Declare a proper C struct
instead. Please fix globally.

And use proper I/O accessors to access device registers. Please fix
globally.
...

> +static ulong lastdec;
As already has been pointed out several times before: this will not
work because BSS cannot be accessed before relocation.
Best regards,
