mpc5200, digsy_mtc: add support for rev5 board version
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
