165 * [QT-3503] Remove PAGED keyword from all Qt-based binaries for
166 MMP-based build systems (abld, SBSv2 (a.k.a. Raptor)).
167 This changes the code paging field in the Symbian (E32Image) header
168 from "paged" to "default". Thus it is left to the configuration
169 of the particular device whether paging is used for the binary or
170 not. All devices that support code paging should have it turned
171 on (the value is stored in the HAL, so can be checked using eg.
172 fshell); data paging may or may not be turned on depending on the
173 device characteristics. Leaving both code and data paging as
174 "default" means that any limitations in the device (eg. around
175 flash wear) can be controlled by that device by disabling the
176 appropriate types of paging rather than being forced by the binary
