Hallo all,
this is RFC patchset to provide remoteproc functionality on
imx7d SoC.
Since current kernel do not have devicetrees for board which
I used for testing, this RFC patchset includes this too.
For testing I used this simple counter written in ASM:
======================================
.syntax unified
.text
.thumb
.int 0x10020000 @ Initial SP value
.int reset + 1
reset:
mov r0, #0x55
ldr r1, =(0x40)
1:
str r0, [r1]
add r0, 1
b 1b
/* Dummy data, required by remoteproc loader */
/* Please FIXME, this part seem to be incorrect */
.data
.section .resource_table, "aw"
.word 1, 0, 0, 0 /* struct resource_table base */
.word 0 /* uint32_t offset[1] */
============================================================
compiled with:
${CROSS}as -o imx7m4.o imx7m4.S
${CROSS}ld -Ttext=0x0 -o imx7m4.elf imx7m4.o
cp imx7m4.elf /srv/nfs/sid-armhf/lib/firmware/rproc-imx_rproc-fw
Functionality was confirmed with current OpenOCD master.
OpenOCD cfg file can be found here:

Comment and suggestions are welcome.
Regards,
Oleksij
