difference to previous board version:
- M29W128GH flash from Numonyx
- SDRAM ISSI IS45S16800 (Option A2 105°C)
- rev5 uses RTC RV-3029-C2
- update cs0 and cs1 baseaddr and length
depending on the detected flash size.
- added Werner Pfister <Pfister_Werner@intercontrol.de>
as maintainer for the digsy board variants
- As the M29W128GH needs a special flash_cmd_reset()
document that in the new file doc/README.cfi.
- move "#endif /* CONFIG_CMD_IDE */" to the right place
- remove LOWBOOT config option for digsy_mtc and digsy_mtc_rev5
boards
- change doc/README.cfi as Stefan Roese suggested

changes against v1:
- add comments from Wolfgang Denk
- add Copyright to board/digsy_mtc/is45s16800a2.h
- change ft_adapt_flash_base() and ft_delete_node()
to void functions, and add printf warnings in it,
if they fail
- to commit message:
- move "#endif /* CONFIG_CMD_IDE */" to the right place
- remove LOWBOOT config option for digsy_mtc and digsy_mtc_rev5
boards
- change doc/README.cfi as Stefan suggested
- remove unneccessary "#if defined(CONFIG_DIGSY_REV5)... #endif"
around gd->bd->bi_flashstart = base;
- add comment why deleting the RTC node in ft_board_setup()
- add Detlev Zundel to cc:
