[PATCH v1 0/2] provide imx rproc driver

[Oleksij Rempel]

this patch set to provide remoteproc functionality on
i.MX7D SoC.

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:
