ramips: set -march=24kec for rt305x and rt3883 to enable use of DSP extension
All known rt305x and rt3883 implementations support at least the 24kec instruction set which includes the DSP extension. For rt288x, the previous value mips32r2 is kept. The cpu target is now set per sub-archtecture, according to cpu-feature-overrides.h of each SoC family. [juhosg: define ARCH_PACKAGES variable for rt305x/rt3883 in order to differentiate the packages compiled with the 24Kec option.] Signed-off-by: Daniel Golle <dgolle@allnet.de> Signed-off-by: Gabor Juhos <juhosg@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35853 3c298f89-4303-0410-b956-a3cf2f4a3e73
