One additional topic to add is the dependency on bootloader update for this as well. I know things are chicken or egg kind of problem, but will be good to mention requires newer version than 2021.xx version of u-boot as this is an "breaking" change. And, if we block both regions off for bootloader compatibility, that is not feasible given the limited SRAM available as well. > > Signed-off-by: Aswath Govindraju > --- > arch/arm64/boot/dts/ti/k3-am64-main.dtsi | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/arch/arm64/boot/dts/ti/k3-am64-main.dtsi b/arch/arm64/boot/dts/ti/k3-am64-main.dtsi > index 6a883f4349cb..7ab3652dfdfb 100644 > --- a/arch/arm64/boot/dts/ti/k3-am64-main.dtsi > +++ b/arch/arm64/boot/dts/ti/k3-am64-main.dtsi > @@ -24,8 +24,8 @@ > #size-cells = <1>; > ranges = <0x0 0x00 0x70000000 0x200000>; > > - tfa-sram@0 { > - reg = <0x0 0x1c000>; > + tfa-sram@1c4000 { > + reg = <0x1c4000 0x1c000>; > }; > > dmsc-sram@1e0000 { > -- > 2.17.1 > -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D
