[U-Boot] [PATCH 1/3] armv8: fsl-layerscape: SPL size reduction

[U-Boot] [PATCH 1/3] armv8: fsl-layerscape: SPL size reduction

[Sumit Garg]

Using changes in this patch we were able to reduce approx 4k
size of u-boot-spl.bin image. Following is breif description of
changes to reduce SPL size:
1. Compile-off mp.c and libfdt.c in case of SPL build.
2. Keep MMU and DCACHE specific variable and functions under
   CONFIG_SYS_DCACHE_OFF macro.
3. Compile-off IFC specific funtion call "init_early_memctl_regs"
   in case of SPL build.

[U-Boot] [PATCH 2/3] armv8: ls1088a: SPL size reduction

[Sumit Garg]

Using changes in this patch we were able to reduce approx 8k
size of u-boot-spl.bin image. Following is breif description of
changes to reduce SPL size:
1. Changes in board/freescale/ls1088a/Makefile to remove
   compilation of eth.c and cpld.c in case of SPL build.
2. Changes in board/freescale/ls1088a/ls1088a.c to keep
   board_early_init_f funcations in case of SPL build.
3. Changes in ls1088a_common.h & ls1088ardb.h to remove driver
   specific macros due to which static data was being compiled in
   case of SPL build.
4. Enable CONFIG_SYS_DCACHE_OFF in case of SPL build as DCACHE is
   not being enabled in case of SPL image but was compiled in to
   add redundant code.

How much space can you save with data cache off? I prefer to leave the 
cache on. Cache is used if PPA is loaded in SPL stage for boost booting 
speed.

As we discussed earlier too, dcache was not enabled in SPL for our layerscape platforms. I have just
removed redundant dcache specific code from SPL. I do save 2KB memory by removing redundant
dcache specific code.

Also we do need more space (approx.. 6KB) on OCRAM for header. As currently we are only supporting
single key in header (Max Size: 4KB) for validation. But actual use-case requires SRK table (8 keys) in
header (Size: 10KB).

Total Available OCRAM for SPL image and header:	88KB

Current SPL image size with GCC 5.4.1 tool-chain:	84KB
Current SPL header size with GCC 5.4.1 tool-chain:	4KB

Required SPL header size with GCC 5.4.1 tool-chain:	10KB

So we need to reduce SPL image size by 6KB more.

That was a mistake when SPL targets were added. It should be enabled.
As I said, if you load PPA in SPL, cache will be enabled for EL2. You 
didn't do it because booting performance is not a concern. If you enable 
falcon boot, this is required.

I understand the difficulty to fit secure boot into OCRAM. Please try 
GCC 6. It has better optimization.

Ok. BTW, do you think latest PPA which claims whole of OCRAM could work with SPL.
I saw crashes in SPL on ls1043ardb with latest PPA enabled in SPL upstream u-boot.

As per my understanding, shouldn't we enable cache as part of main u-boot image
running in EL2? Also in case of SD, it uses DMA to copy main u-boot image or kernel
in case of falcon boot to DDR. I am not sure how much booting performance gain
can we get by enabling dcache in SPL.

Sure I will use GCC 6 for upstream. But for LSDK, we have to stick with GCCC 5.4.1
for now.

I don't agree D-cache should be off for SPL boot. Please find other way 
to reduce SPL image size.

Sure, let me use GCC 6.2 to reduce SPL image size in upstream rather than compiling-off
D-cache code.

But I still don't see ls1088ardb sd boot support in upstream.

Ashish,

By when can I expect ls1088ardb sd boot support in upstream?

SD boot is not completed. I don't see RCW in the final image. Pending

I will wait for SD boot patches to be accepted in upstream. As reducing SPL size
for ls1088ardb in upstream does only makes sense once we have base platform
support merged in upstream.

York,

I have just sent reworked patches without removing dcache cache code. It's been working
only with toolchain above GCC 6 that reduces SPL size.

Thanks.
What do you mean "working only with toolchain above GCC 6"? Do you mean
the size would be too large using older toolchain?

Yes for LSDK, tool-chain being used is GCC 5.4.1. Following is analysis with LSDK too-chain:

SPL size for Secure boot image without dcache code:	83K
Available max OCRAM memory size for SPL image:	84K
SPL size for Secure boot image with dcache code:	85K

So for LSDK we have remove dcache code for Secure boot to work with current SPL size reduction.

If you are out of space for LSDK, go ahead to remove the dcache code.
For upstream U-Boot, I want to keep those code for falcon boot. We are
going with GCC 6 anyway.
