Subject: [PATCH 3/5] MIPS: Move mips_cm_probe after prom_init
Date: Tue, 07 May 2024 10:01:51 +0100	[thread overview]
Message-ID: <20240507-cm_probe-v1-3-11dbfd598f3c@flygoat.com> (raw)
In-Reply-To: <20240507-cm_probe-v1-0-11dbfd598f3c@flygoat.com>

Move mips_cm_probe after prom_init so we can use fdt functions
in mips_cm_probe to obtain essential information.

Impat for all systems that may have CM in system:
- geneirc: Adjusted code to accommodate this change
- Lantiq: No impact, CM configuration won't be changed at all
- ralink: Called mips_cm_probe on it's own, in prom_init->prom_soc_init
- malta: No impact, CM address comes from CP0_CMGCR
