soc: qcom: mdt_loader: Use request_firmware_into_buf()

2017-08-08T22:41:23+00:00

By switching to the request_firmware_into_buf() we load the segment data straight into the preallocated buffers, reducing the need for allocating scratch buffers for these. In particular the modem firmware consists of multiple segments in the range 5-15MB, making this worth while. Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

remoteproc: qcom: mdt_loader: Use signed type for offset

2017-02-22T10:07:13+00:00

In the transition from using rproc_da_to_va(), the type of the load offset became unsigned. This causes the subsequent check to let negative values less than p_memsz + mem_size through and we write outside of the buffer. Change the type back to a signed value to catch this.

remoteproc: Move qcom_mdt_loader into drivers/soc/qcom

2017-02-06T16:57:25+00:00

With the remoteproc parts cleaned out of the MDT loader we can move it to drivers/soc/qcom. Acked-by: Andy Gross Signed-off-by: Bjorn Andersson
