It could be supported by abiv2 (ck807, ck810, ck860). > > Signed-off-by: Guo Ren > Cc: Thomas Petazzoni I've split this patch into two: one removing the DSP option, one adding the VDSP option. Also, I've added the appropriate Config.in.legacy option to replace BR2_CSKY_DSP. Best regards, Thomas -- Thomas Petazzoni, CTO, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
