No particular objections to this change, current platforms support by this change fall under 3 categories: - BCM7xxx using a CFE providing a firmware interface you call into using code from arch/mips/fw/cfe/ - BCM63xx CFE - BCM33xx using Aeolus [1] The first two are likely not going to be changed since these are currently deployed products/systems, however the latter could be changed to match UHI as Kevin proposed a while ago. > > Signed-off-by: Jonas Gorski <jogo@xxxxxxxxxxx> > --- > arch/mips/bmips/setup.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/arch/mips/bmips/setup.c b/arch/mips/bmips/setup.c > index fae800e..526ec27 100644 > --- a/arch/mips/bmips/setup.c > +++ b/arch/mips/bmips/setup.c > @@ -149,6 +149,8 @@ void __init plat_mem_setup(void) > /* intended to somewhat resemble ARM; see Documentation/arm/Booting */ > if (fw_arg0 == 0 && fw_arg1 == 0xffffffff) > dtb = phys_to_virt(fw_arg2); > + else if (fw_arg0 == -2) /* UHI interface */ > + dtb = (void *)fw_arg1; > else if (__dtb_start != __dtb_end) > dtb = (void *)__dtb_start; > else > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
