The last dependency for enabling multiplatform support for omap2+ is now
finally gone with commit62e4d357(ARM: 7609/1: disable errata work-arounds which access secure registers) that was preventing booting omap4. Note that make uImage will no longer work properly because of unspecified load address, so uImage needs to be created manually with: $ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \ -n "Linux" -d zImage-omap2plus uImage-omap2plus You can also boot minimal vexpress configuration using qemu with: $ qemu-system-arm -machine vexpress-a9 -m 1024 -net nic -net user -serial stdio \ -append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait" \ -kernel zImage-omap2plus -initrd initrd.img -sd rootfs.img Please note that some custom defconfigs now need to be updated to include the following options: CONFIG_ARCH_MULTIPLATFORM=y CONFIG_ARCH_MULTI_V7=y CONFIG_ARCH_OMAP2PLUS=y And possibly also: CONFIG_ARCH_MULTI_V6=y Updating is needed at least for RMK's minimal allnoconfig files. And if you need DEBUG_LL for earlyprintk, you now have to select the debug port manually with Kconfig. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJQ8GexAAoJEBvUPslcq6VzVYQP+gOn4LPaNRu1YMOLjVGlw5Za ceUQd5+QQBzoiRhETkiFTS8d/lDr3BYfYVpJDl3xg3dtfDJaqoWLz6DhpVyZLssW Ua29BO/P4B/NROaMttusNKv8iO7ivxj9afZ2U8R5VzNXjSBBD+xwAkBoMiewX54y ILGj0u3Cz+/MuyM3Px/OQi73JnSS/77PO8M+pB+d49abFirLFeQkmR+uhZNONKwI sQXvwmNBMnYn3JDo/xxKycaOCIoTpq3T34wASCCeknVhh5F0X6FTUMej+s3Erluv iH0T3kBTB0/B00vKHY725yy69LHD6cszVFKh33Yvkcyt4XA5GAMbWmEZwoEh1feu Xg6WvZOJYQUAz6VmYcIRT6J6jiyeeiffIeb+o8SE0v6d0iCtAo3czhvs3j7eGHoK LHEW92B+mxY51UaqJzzVQJa8dZsHFgDMVcMiFM+vm0bnHBKXl470/rfSUdUuH3WY TJeFG11tdlumW8Ug8s8KBiIXOQbsUgfzGEfKe8bEOjQHdEPrvxPVazSE4Pd4+i91 6wATfnxNduQwS5nUWH8OE+Fm0IZ0ltkXXq/Zr2YE0FkHBMNp4FoKdwSSMxhT1GUL PFOV1MMWkflA7+d2G15plMS5SjSWC6br1HuXrF1MBpf1D2sWEGYvGH4wQxHUrV/j nNldw7hhC0gFBlLAx2Lw =sYWs -----END PGP SIGNATURE----- Merge tag 'omap-for-v3.9/multiplatform-enable-signed-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/multiplatform From Tony Lindgren: The last dependency for enabling multiplatform support for omap2+ is now finally gone with commit62e4d357(ARM: 7609/1: disable errata work-arounds which access secure registers) that was preventing booting omap4.
