Re: [U-Boot] [PATCH 2/8] ea20: remove board

From: Bartosz Golaszewski bgolaszewski@baylibre.com

This board still doesn't select CONFIG_DM and seems to be umaintained. As it makes progress on modernizing several DaVinci drivers more difficult and the maintainer has not expressed interest in updating it, this patch proposes to remove it.

Acked-by: Stefano Babic sbabic@denx.de
