For the compatibility of NXP internal legacy kernel before 4.19 which is based on uart ram script and upstreaming kernel based on uart rom script, add both uart ram/rom script in latest sdma firmware. By default uart rom script used. Besides, add two multi-fifo scripts for SAI/PDM on i.mx8m/8mm and add back qspi script miss for v4(i.mx7d/8m/8mm family, but v3 is for i.mx6). rom script: uart_2_mcu_addr uartsh_2_mcu_addr /* through spba bus */ am script: uart_2_mcu_ram_addr uartsh_2_mcu_ram_addr /* through spba bus */ Please get latest sdma firmware from the below and put them into the path (/lib/firmware/imx/sdma/): https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git /tree/imx/sdma Signed-off-by: Robin Gong <yibin.gong@nxp.com> Acked-by: Vinod Koul <vkoul@kernel.org> --- drivers/dma/imx-sdma.c | 17 +++++++++++++++-- include/linux/platform_data/dma-imx-sdma.h | 8 ++++++-- 2 files changed, 21 insertions(+), 4 deletions(-)
