Subject: apm821xx: make ata-dwc as a standalone module
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fjow.git;a=commitdiff_plain;h=fd9dc10530ef04de58fd36947c03113345e9b949

apm821xx: make ata-dwc as a standalone module

In order to cut down on the Netgear WNDR4700, the ata
driver can be outsourced. This helps other apm821xx
devices too to save up on kernel size (~200 kb).
