Got a really nice idea..
<
f_>
Let's dump all DRAM registers in both BL2 and SPL and compare
<
f_>
How could I do that in BL2? you may ask..
<
f_>
Just run custom code as BL31!

If you own bl2 there's not really any limits on what you can do :)
<
f_>
I don't
*own* BL2..
<
f_>
just one funny thing..thanks to ghidra I know all function addresses..so I can use bl2 functions :)
<
f_>
Am a lazy person..too lazy to reimplement serial_puts when I can just make use of BL2's..
<
f_>
Actually I could run it as bl21..
<
f_>
bl21 runs
*before* DRAM init
<
f_>
amlogic-boot-fip makes replacing BL31 very easy..
<
f_>
BL2 will panic for sure :).

Also thought playing with BL2 strings was a good idea :P

and everything after that, is my code.
<
f_>
I just had fun with BL2 strings, that's all :D
<
f_>
I'll do the same for SPL, and compare.
<
f_>
these are either PUB or PCTL regs.
