[v2] arm64: dts: qcom: Fix remoteproc memory base and length

[PATCH v2 16/19] arm64: dts: qcom: sm6350: Fix MPSS memory length

Posted by Krzysztof Kozlowski 1 year ago

The address space in MPSS/Modem PAS (Peripheral Authentication Service)
remoteproc node should point to the QDSP PUB address space
(QDSP6...SS_PUB) which has a length of 0x10000.  Value of 0x4040 was
copied from older DTS, but it grew since then.

This should have no functional impact on Linux users, because PAS loader
does not use this address space at all.

Thanks. I got the access to sm6115 and sdx75, so I will send v3 with 4
new patches for them.

Best regards,
