* brcm47xx: activate some compiler optimizations for 74K CPUsHauke Mehrtens2014-06-071-0/+3
| | | | | | | | | | | With this patch the mips74k subtarget will be compiled with optimized compiler options to generated smaller and faster code. This currently breaks broadcom-wl, because the binary blob is only compiled with mipsr1 support. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 41050
* brcm47xx: mips74k: optimize kernel configHauke Mehrtens2014-06-071-0/+10
| | | | | | | | | This saves abount 15 kB of compressed kernel size. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 41043
* brcm47xx: add mips74k subtarget for newer devicesHauke Mehrtens2014-06-055-0/+81
All new devices (with MIPS 74K CPU) are based on BCMA SoC and have Ethernet core supported by bgmac. Create a new subtarget to generate optimized builds. This is just a beginning, further tweaks (like kernel configuration) are still possible. This decreases default root.squashfs by ~128 kB.
