[v3,00/17] hw/arm: Add NPCM8XX Support

Message

Hao Wu Feb. 6, 2025, 1:30 a.m. UTC

Changes since v2:

1. Update doc to include npcm845-evb description
2. Add g_assert for register size in CLK and GCR enter_reset function
3. Fix various 8xx SoC and board file issues.

Changes since v1:

1. Updated vbootrom and pc-bios
2. Split out CLK/GCR patches into refactoring and adding new features
3. Fixed a few misc items from the patches.

NPCM8XX BMCs are the successors of the NPCM7XX BMCs. They feature
quad-core ARM Cortex A35 that supports both 32 bits and 64 bits
operations. This patch set aims to support basic functionalities
of the NPCM7XX BMCs. The patch set includes:

1. We derive most devices from the 7XX models and
made some modifications.
2. We have constructed a minimum vBootROM similar to the 7XX one at
https://github.com/google/vbootrom/tree/master/npcm8xx
and included it in the patch set.
3.  We added a new NPCM8XX SOC and an evaluation
board machine npcm845-evb.

The OpenBMC for NPCM845 evaluation board can be found at:
https://github.com/Nuvoton-Israel/openbmc/tree/npcm-v2.10/meta-evb/meta-evb-nuvoton/meta-evb-npcm845

The patch set can boot the evaluation board image built from the source
above to login prompt.
