hushmoney: it depends on the particular device, but iirc the rk3399 devices in u-boot do that.

van: black magic probe is kinda dope.

any1: Ah, so that probably means some kernel patch to change the dts files, my first guess anyhow

<hushmoney>
hanetzer: thanks. why does it depend on the device? once the firmware has loaded and started u-boot isn't it entirely up to u-boot at that point?
<hanetzer>
hushmoney: I don't think every one of them has it implemented :)
<hanetzer>
so, while in theory I think any u-boot device can do it, not all of them have the plumbing hooked up.
<hushmoney>
by "every one of them" you mean every one of what? every u-boot implementation?
<hanetzer>
every device supported by uboot.
<hushmoney>
so what isn't clear to me is - are you describing a u-boot code deficiency, or a device firmware deficiency?
<hanetzer>
I mean, depending on how you look at it those could be the same thing :)
<hanetzer>
but for example. the rk3288 and rk3399. arm and arm64 respectively. the former, last I looked, does not bundle u-boot into a FIT image. the latter does (along with ATF iirc)
<hushmoney>
how can i tell if my device supports it?
<hushmoney>
my device has firmware that executes before u-boot and is responsible for finding and loading the bootloader, that's why i'm confused
<hanetzer>
what kind of device?
<hushmoney>
it's a xilinx versal
<hanetzer>
consult the datasheets, I guess. note: the rk3399 I mentioned first executes the spl (after bootrom), which loads the u-boot+atf fit image, so I don't think FIT loading is an inherit characteristic of the SoC

ok, thanks for your patience. this is all new to me
<hanetzer>
hushmoney: Its not new to me, but I'm not quite adept at it yet, so all this info may be subtly wrong. however, I find the best way to get the write answer is to assert the wrong answer and wait for the corrections, so I think in this case I'm at least passibly correct :)
<hanetzer>
*right answer. wtf I can english I swear.
<hushmoney>
yes i am also familiar with this tactic :)

hanetzer: I am trying to learn how the mmu works in detail.

And I want to be able to inspect the special registers in a53/72 cores
<van>
so all though I have the code and it works.. I want to know how. :)
