sh: Add support 32-Bit Extended Address Mode to sh7785lcr
We can built 'make sh7785lcr_32bit_config'. And add new command "pmb" for this mode. This command changes PMB for using 512MB system memory. Signed-off-by: Yoshihiro Shimoda <shimoda.yoshihiro@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

=============================
|

|

You can choose configuration as follows:
|
||||
|
||||
- make sh7785lcr_config
|
||||
- make sh7785lcr_32bit_config
|
||||
|
||||
When you use "make sh7785lcr_config", there is build U-Boot for 29-bit
|
||||
address mode. This mode can use 128MB DDR-SDRAM.
|
||||
|
||||
When you use "make sh7785lcr_32bit_config", there is build U-Boot for 32-bit
|
||||
extended address mode. This mode can use 384MB DDR-SDRAM. And if you run
|
||||
"pmb" command, this mode can use 512MB DDR-SDRAM.
