| skipwich | hi, been following the project for a bit and been mostly lurking but interested in soon getting a Reform of my own | 00:12 |
| minute | skipwich: cool | 00:13 |
| skipwich | minute: chiming in mainly to out-of-band reply to your latest toot on the rk3588 - have you seen the Collabora folks notes on the processor? they're doing most of the dev for that cpu in linux | 00:14 |
| skipwich | https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md | 00:14 |
| minute | skipwich: oh i hadn't seen that yet, thank you | 00:14 |
| skipwich | you're welcome! I've been following that cpu's support in linux for a bit now, though they seem to be doing most of their work on the Radxa Rock 5B board, so ymmv with the firefly if using their branch | 00:18 |

| minute | rk3588 feels like a pretty complex beast | 00:27 |
| hramrach | but it's true that most of the time it makes sense to store TF-A in memory, and then it needs to be initialized | 00:29 |

| hramrach | The SoC typically has very little internal memory so the TF-A will likely need the external RAM to operate in most cases | 16:23 |
| + mark_ (~mjw@gnu.wildebeest.org) | 16:25 | |
| f_ | Oh that's what you meant. | 16:25 |
| f_ | Of course. | 16:26 |
| hramrach | There's the thing that once Linux is up and running all the SoCs look mostly the same but at the time TF-A is bootstrapped you get to see some platform details that can vary a lot from one Soc to another ;-) | 16:28 |
| hramrach | some would use the CPU cache for early operation which is unusable once DDR is initialized, some have dedicated internal memory of varying size ... | 16:30 |
| f_ | Indeed. | 16:30 |
| f_ | amlogic SoCs have SRAM. | 16:30 |
| f_ | the SRAM can still be used once DRAM is initialised though AFAICT | 16:31 |
| hramrach | and if it's big enough and can be protected it could technically hold TF-A, and it would not need to initialize external RAM to run then | 16:32 |
| hramrach | it depends on other architectural details if such setup makes sense in some way, no ida about Amlogic | 16:34 |
| f_ | It's not big enough for U-Boot I guess. | 16:37 |
| f_ | Either way Amlogic decided to do DRAM init in BL2..for whatever reason | 16:37 |
| f_ | (except on newer SoCs it's a huge mess with BL2X, BL2E, ?????) | 16:38 |
| hramrach | they figured that different devices need different RAM settings so added plugns - at least that's what it looks like from some of the diagrams. | 16:40 |
| hramrach | And not initializing the RAM in the first place would avoid the mess - so long as SPL or TPL can be loaded into SRAM and do custom initialization only then | 16:42 |
| hramrach | Also I suspect some platforms do something like initializing the RAM at some very low frequency, and only later u-boot re-programs it to run at the frequency specific to the device | 16:43 |
| hramrach | The plugin design is based on the proprietary software philosophy - Amlogic provides one binary, and board vendors provide a plugin to customize it for thei board design. u-boot does not need to follow it so long as it can do without the proprietary plugins, which is typically not the case initially. | 16:47 |
