GPMC_CONFIG misses LIMITEDADDRESS bit

Hi.

On new OMAP-based SoCs (like OMAP5 and DRA74x) there is no LIMITEDADDRESS bit in GPMC_CONFIG register. This bit marked as RESERVED now. But GPMC_REVISION for those SoCs has the same value (0x60) as for OMAP4. So OMAP5-based and OMAP4-based SoCs GPMC revision is 6.0.

The question is next: am I actually able to use LIMITEDADDRESS bit on DRA74x (despite it's description is missing in TRM)? If no -- then why GPMC on DRA74x has the same revision as on OMAP4?
