Hi,
As announce during OLS conference, it's plain to use kconfig to manage board configuration.
For this purpose and Makefile conditional compile we're move CFG_ macro to new CONFIG_ marco
For memory
There are two classes of configuration variables:
* Configuration _OPTIONS_: These are selectable by the user and have names beginning with "CONFIG_".
* Configuration _SETTINGS_: These depend on the hardware etc. and should not be meddled with if you don't know what you're doing; they have names beginning with "CFG_".
to keep CFG_ meaning we will rename them in the following change
1) Basic config
For environment we will use CONFIG_ENV_ (will be done this merge windows)
For configuration settings CONFIG_SYS_
additional proposition
2) Extra config
For memory settings CONFIG_MEM_ or CONFIG_SYS_MEM_
For PCI settings CONFIG_PCI_ or CONFIG_SYS_PCI_
For USB settings CONFIG_USE or CONFIG_SYS_PCI_
For flash settings CONFIG_FLASH or CONFIG_SYS_FLASH_
For nand settins CONFIG_NAND or CONFIG_SYS_NAND_
For dtt settgins CONFIG_DTT or CONFIG_SYS_DTT
etc...
Comments are welcome.
The move to new style will be done for the beggining of the next merge window
Best Regards, J.
