[PATCH] Exporting reserved APIs in GPMC library.

[PATCH] Exporting reserved APIs in GPMC library.

[Syed Mohammed, Khasim]

[-- Attachment #1: Type: text/plain, Size: 474 bytes --]

Hi,

The attached patch is to export two APIs (gpmc_cs_set_reserved and
gpmc_cs_reserved) of GPMC library.

This allows other libraries and drivers to access these APIs with out
doing a gpmc_request. 

Reason: If I have already configured a GPMC CS in boot loader I might
not be interested in doing the same again in Kernel. However I might
want to reserve this particular CS so that it doesn't show as free when
others do a gpmc_request. 

Regards,
Khasim

Pushing your two patches today as a single patch. Left out the HISTORY
part to cut down on clutter as it already shows up in git.
