So far i have not come across a toolchain (or a way to create toolchain)
to create !MMU user space executables for Cortex-A.
Now able to reach prompt using buildroot initramfs, Thanks to
Peter Korsgaard for suggesting the way to create user space executables
for !MMU Cortex-A.
multi_v7_defconfig was used & all platforms except TI OMAP/AM/DM/DRA &
Freescale i.MX family was deselected. ARM_MPU option was disabled as
Vladimir had given an early warning. DRAM_BASE was set to 0x80000000.
During the course of bringup, futex was causing issues, hence FUTEX was
removed. L1 & L2 caches were disabled in config. High vectors were
disabled & vectors were made to remap to base of RAM. An additional OMAP
specific change to avoid one ioremap was also required.
For the sake of completeness,
SMP was disabled & flat binary support enabled in Kernel.
