[U-Boot] [PATCH 02/11] arm64: zynqmp: mp: Correct the R5 release sequence

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com>

This patch corrects the R5 release sequence by adding the
below steps.
1. Flush dcache to ensure that image loaded into memory.
2. Keep R5 reset just to ensure R5 in reset.
3. Disable caches before accessing TCM as with out this
   A53 can do speculative and may result in ECC failures
   if TCM's are not initialized. So, it is always better
   to disable dcaches before accessing TCM and enable back.

[U-Boot] [PATCH 03/11] arm64: zynqmp: Provide a Kconfig option to use specified memory for MMU table

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com>

This patch provides a Kconfig option to use specified
memory for MMU table using reserve_mmu platform specific
routine. Here we used TCM space for MMU table.

[U-Boot] [PATCH 04/11] tools: mkimage: Extend mkimage to also include pmufw

[Michal Simek]

This is generated command line when PMUFW_INIT_FILE is setup.

./tools/mkimage -T zynqmpimage -R ./"" -n
./"board/xilinx/zynqmp/pmufw.bin" -d spl/u-boot-spl.bin spl/boot.bin

pmufw has to be in binary format and mkimage is using dynamic
header size generation without using calloc function based on pmufw
size. Boot.bin header is filled with pmufw size and pmufw is copied to
header data section. When header is generated mkimage append
u-boot-spl.bin.

Can you reword this a bit? It is a bit confusing to read.

Help should include full details. Abbreviations should be explained.

Also are you saying that this tacks something new onto u-boot.bin?
Where is that happening and how is it found at run time? I'm wondering
is this might be a job for binman?

Nope. It is really just boot header follows by pmufw.bin and
u-boot-spl.bin >> boot.bin

bootrom based on headers know that there is pmufw.bin which is consumed
by PMU unit which is microblaze cpu. And SPL runs on a53s.

I am aware about binman when you send the first version but haven't had
any time to look at it. This mkimage extension is something I used for
pretty long time and I didn't see any issue for this usecase.

boot.bin format can contain multiple sessions for example ATF, full
u-boot, Linux, rootfs, app for arm R5, bitstream, etc. For generating
this boot.bin maybe binman could be right tool but Xilinx has own tools
called bootgen which is capable to generate this image. It also contains
encryption and authentication parts.

Thanks,
Michal

[U-Boot] [PATCH 05/11] arm64: zynqmp: Enable config DEFINE_TCM_OCM_MMAP if CONFIG_MP defined

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com>

This modifies default value of config DEFINE_TCM_OCM_MMAP
to yes if CONFIG_MP is defined MP supports needs OCM and TCM
