9ce3bf225e remoteproc: Use size_t type for len in da_to_va
With upcoming changes in elf loader for elf64 support, section size will
be a u64. When used with da_to_va, this will potentially lead to
overflow if using the current "int" type for len argument. Change
da_to_va prototype to use a size_t for len and fix all users of this
function.

99a31adfb2 remoteproc: imx_rproc: Slightly simplify code in 'imx_rproc_probe()'
We can return directly at the beginning of the function and save the 'err'
label.
We can also explicitly return 0 when the probe succeed.

68a39a3e9f remoteproc: imx_rproc: fix return value check in imx_rproc_addr_init()
In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.

a0ff4aa6f0 remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver
Provide a basic driver to control Cortex M4 co-processor found
on NXP i.MX7D and i.MX6SX.
Currently it is able to resolve addresses between M4 and main CPU,
start and stop the co-processor. Other functionality is not provided
or test.

This driver was tested on NXP i.MX7D and expected to work on
i.MX6SX as well.
