Gregory Nutt f8170550e1 ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. It changed CPSR while in kernel. That will crash is the new CPSR is user mode while executing in kernel space. Fixed by adding a SYS_context_restore system call. There is an alternative, simpler modification to up_fullcontextrestore() that could have been done: It might have been possible to use the SPSR instead of the CPRSR and then do an exception return from up_fullcontextrestore(). That would be more efficient, but I never tried it.		2014-09-12 08:04:27 -06:00

Make.defs	Add logic that will permit us to build user libraries with different CFLAGS than kernel code. This is needed because we need the -fno-common option when building ELF code to prevent SHN_COMMON relocations	2014-09-09 15:45:37 -06:00
setenv.sh	Rename SAMA5D4-EK kernel configuration to knsh for consistency with naming for other platforms	2014-09-08 11:05:05 -06:00
