[PATCH v2 09/13] net: synquacer: Add netsec driver
Masami Hiramatsu
masami.hiramatsu at linaro.org
Sat Apr 17 01:38:47 CEST 2021
From: Jassi Brar <jaswinder.singh at linaro.org>
Add SynQuacer's NETSEC GbE controller driver.
Since this driver will load the firmware from SPI NOR flash,
this depends on CONFIG_SYNQUACER_SPI=y.
Signed-off-by: Jassi Brar <jaswinder.singh at linaro.org>
