core: Rework REGMAP symbols implementation

2026-03-30T22:59:35Z

As exposed by "make randconfig", we have an issue with the dependencies for REGMAP (and xPL variants). As this is a library function, it should always be selected and not depended on by other functionality. This is largely done correctly today, so just correct the few outliers.

arm: airoha: introduce EN7523 helpers to get SCU and CHIP_SCU regmaps

2025-11-07T22:00:58Z

We need access SCU and CHIP_SCU regmaps in several places (clk-airoha, reset-airoha, airoha_eth). Unfortunately these regmaps can't be easily retrieved with a common code, because of different Airoha SoCs uses a different dts structure. To make life easy we can write a commonly named SoC specific helpers for these tasks. This patch implements helpers for Airoha EN7523 SoC. Signed-off-by: Mikhail Kshevetskiy

arm/airoha: partly revert support of multiple RAM size for an7581

2025-10-15T21:08:27Z

Partly revert commit 726404a66c773 ("airoha: rework RAM size handling to support multiple RAM size"). The general idea is good, but the call of get_ram_size((void *)gd->ram_base, SZ_8G); produces the following result on my an7581 board with only 1Gb of memory: "Synchronous Abort" handler, esr 0x96000004 elr: 0000000081e201c8 lr : 0000000081e20160 (reloc) elr: 00000000bff501c8 lr : 00000000bff50160 x0 : 0000000180000000 x1 : 0000000100000000 x2 : 000000000000002e x3 : 0000000000000002 x4 : 000000001fbf0000 x5 : 0060000000000401 x6 : 0000000000000000 x7 : 00000000bffdb268 x8 : 0000000000000060 x9 : 00000000bffdb2c8 x10: 0000000000000000 x11: 0000000000000060 x12: 00000000bffdb268 x13: 00000000841c56d0 x14: 00000000841c56d0 x15: 0000000000000000 x16: 00000000841506e4 x17: dd7fe29aec3b07e8 x18: 00000000bf710e00 x19: 0000000080000000 x20: 0000000000000000 x21: 0000000020000000 x22: 0000000200000000 x23: 0000000000000001 x24: 0000000040000000 x25: 00000000bf708e78 x26: 00000000bf7bdca0 x27: 0000000000000000 x28: 0000000000000000 x29: 00000000bf708e20 Code: 910943ff d65f03c0 d37df2a1 8b150e60 (f8616a62) Resetting CPU ...

arm/airoha: an7581 ignores CFG_MAX_MEM_MAPPED value

2025-10-15T21:08:27Z

This partly fix commit 726404a66c773 ("airoha: rework RAM size handling to support multiple RAM size") The function get_effective_memsize() do not see non-global defines of CFG_MAX_MEM_MAPPED, so the effective memory size will not be changed. Fix the issue by putting definition of CFG_MAX_MEM_MAPPED to the proper place.

airoha: rework RAM size handling to support multiple RAM size

2025-10-07T23:11:49Z

There are multiple version of the same reference board with different RAM size and it's not enough to base the RAM size entirely from DT. To better support it use the get_ram_size way to scan for the actual RAM size of Airoha SoC and increase the size of the memory map. Also rework the memory map to account for 2 memory map. The first one of 2GB for 32bit DMA and for safe usage of U-Boot. The second one for the rest of the RAM since up to 8GB are supported.
