Subject: [PATCH] remoteproc: imx_rproc: correct i.MX93 DRAM mapping

From: Peng Fan <[email protected]>

According to updated reference mannual, the M33 DRAM view of
0x[C,D]0000000 maps to A55 0xC0000000, so correct it.

But how did this work before? Were some SoC released with the old mapping?

The current m33 firmware release with Linux SDK only has
TCM version, so I not have image to test the DDR mapping.

Initially we got the information that M33 mapping of DRAM.
DRAM (offset 0 MB) DRAM 80000000
DRAM (offset 256 MB) DRAM A0000000
DRAM (offset 512 MB) DRAM C0000000

However the information is wrong after we check more,
there is an 256MB hole, 0MB [0x80000000, 0x8fffffff],
512MB [0xa0000000, 0xafffffff],
1024MB [0xc0000000, 0xcfffffff]

I use JTAG to confirm it.

Thanks,
Peng.

As it is regularly the case, you have not answered all my questions.

The DRAM mapping was not tested, I just wrote them down according
to the information I had. In this patch, I just fix the mapping at address
0xC0000000, I not add 0xA0000000, I may also add it or use a separate
patch, which would you prefer?

The i.MX93 SoC is still in pre-production phase, and there is no public
Information for now.

Seperate patch? This is a seperate patch...

That is all I wanted to know. Other implementation can't be affected by this
change because the sillicon is still under development. Simple isn't?

I am applying this patch.

I mean the DRAM mapping still not cover 0xA0000000, 0xB0000000. The
current mapping is below:
/* DDR */
{ 0x80000000, 0x80000000, 0x10000000, 0 },
{ 0x90000000, 0x80000000, 0x10000000, 0 },

{ 0xC0000000, 0xc0000000, 0x10000000, 0 },
{ 0xD0000000, 0xc0000000, 0x10000000, 0 },

For 0xA/B0000000, I could add later when I get an M33 image that
really use that address in future.

Others are not affected.
