This commit introduce the initial support for machine specific lowlevel initialization (e.g. RAM controller or cache memory). To return from mach_init_lowlevel() it uses explicit mach_init_lowlevel_return label. This saves ra register for using inside mach_init_lowlevel() Signed-off-by: Antony Pavlov <antonynpavlov@xxxxxxxxx> --- arch/mips/boot/start.S | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/arch/mips/boot/start.S b/arch/mips/boot/start.S index 10f7691..238e2c4 100644 --- a/arch/mips/boot/start.S +++ b/arch/mips/boot/start.S @@ -74,6 +74,14 @@ __start: and k0, k1 mtc0 k0, CP0_STATUS +#ifdef CONFIG_MACH_DO_LOWLEVEL_INIT + b mach_init_lowlevel + nop + +mach_init_lowlevel_return: +EXPORT(mach_init_lowlevel_return) +#endif + /* copy barebox to link location */ ADR a0, _start, t1 /* a0 <- pc-relative position of _start */ -- 1.7.10 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
