Re: [PATCH v8 03/11] arm64: dts: ti: k3-am62a-mcu: Add R5F remote proc node

[Daniel Schultz]

Hi,

I'm unable to load the latest TI firmware 
(98efd20ec71f8c1c8f909d34ab656731) with this patch.

[    7.012889] remoteproc remoteproc1: 79000000.r5f is available
[    7.032640] remoteproc remoteproc1: powering up 79000000.r5f
[    7.038626] remoteproc remoteproc1: Booting fw image 
am62a-mcu-r5f0_0-fw, size 53140
[    7.057209] remoteproc remoteproc1: bad phdr da 0x79100000 mem 0x47ea0
[    7.064716] remoteproc remoteproc1: Failed to load program segments: -22

I figured out that the mcu sram node disappeared in v5. Apparently 
adding it back manually doesn't solve this problem. Any idea what's wrong?
