Hey all, trying to check something in U-Boot. on rk3399, 0x100000 is in regular DDR space, yes?

Tartarus: I'm probably too late on this, but according to the memory map in the RK3399 TRM that should be correct if I'm reading this right. https://0x0.st/XFrz.png

Tartarus: wdym by "regular DDR space"?
<qschulz>
but likely not\
<qschulz>
if I do maths properly
<qschulz>
0x100000 is 1MiB
<qschulz>
and the first 2MiB on DRAM are reserved for TF-A
<qschulz>
on Rockchip

<diederik>
it's a change to rk356x/rk3568 dtsi files and that fixes the DT *binding* ?
<mmind00>
diederik: the binding commit introduced reset-names property (including a minItems:1), so broke rk3568 devicetree
<diederik>
I understood there was a relation, but I didn't realize it would be recorded as fixing the binding ... or I'm reading/interpreting that incorrectly
<mmind00>
diederik: it doesn't fix the binding ... "Fixes: foo" means "that commit broke "something" and "this" commit fixes that _issue_
<mmind00>
diederik: "Fixes" establishes a relation between commits, not between the content
<diederik>
then I've learned something new today. Thanks for that :)
<diederik>
I always thought it meant "that was wrong and this fixes that"
<diederik>
IOW: I thought it was about the content
<mmind00>
it can be i.e. a Fix can also be for the code-_change_ itself ... but can also be about breakage caused somewhere else

does anyone know why writing to vop registers doesn't work?
<Daanct12>
it would just not apply at all

Daanct12: the is this reg_cfg_done bit I think?
<Tartarus>
qschulz: Ah, hm. I was looking at include/configs/rk3399_common.h and CFG_IRAM_BASE and thought TF-A got put in there and not DDR space.
<Daanct12>
mmind00: yeah but this is a rk3568 platform..
<Daanct12>
bit15 is always set and the TRM doesn't say much
<qschulz>
Tartarus: pretty sure TF-A is in SRAM but has reserved memory in DRAM, but wouldn't swear on my life :)
<Tartarus>
OK
<Tartarus>
FWIW, I'm looking at two chromebooks and so maybe they don't use TF-A, I dunno
<qschulz>
Tartarus: TF-A is necessary for any Aarch64 to boot the Linux kernel as far as I know

rk3588 trm has more stuffs in application notes but they don't seem to be quite useful
* Daanct12
thinks it wants everything to be written all at once
