I don't understand why we remove 0x1000 here from the size of the SRAM.

If I go back in git history, I found 
915e09814a83128fee8b87b2ee2e5f4a17e04a01 which states it's total SRAM - 
size used by BootROM.

Can anyone provide feedback on how one is supposed to find this out? I 
think it's not the first time I'm confused by this and I'm not sure 
anyone's answered me before, but in any case, documenting this would be 
much welcome :)

The RK3576 does have 512KiB of SRAM so the base value before subtracting 
is fine :)

Cheers,
Quentin
