Subject: [PATCH v16 11/12] dmaengine: imx-sdma: add uart rom script
Date: Wed, 14 Jul 2021 18:20:51 +0800	[thread overview]
Message-ID: <1626258052-22198-12-git-send-email-yibin.gong@nxp.com> (raw)
In-Reply-To: <1626258052-22198-1-git-send-email-yibin.gong@nxp.com>

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
