[U-Boot] [PATCH V5] ppc4xx: Add 405EP based PMC405DE board

Matthias Fuchs
2009-07-21T10:22:23Z

patch v2:
- coding style cleanup
- added CONFIG_PHY1_ADDR
patch v3:
- refactor PLL reconfiguration code
- beautify some one-line-functions
patch v4:
- remove 'sbe' command
- add CONFIG_CMD_CHIP_CONFIG support
- use ppc4xx_gpio struct for GPIO access
- use set/clrbits_be32 to modify GPIO registers
- add CPLD register struct
patch v5:
- add patch history to commit message
