From: Icenowy Zheng Date: Sat, 29 Jan 2022 15:23:07 +0000 (-0500) Subject: mach-sunxi: Add support for SUNIV architecture X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=cfe673cda7169017b0afa139849b623f4f2f7470;p=u-boot.git mach-sunxi: Add support for SUNIV architecture Add support for the suniv architecture, which is newer ARM9 SoCs by Allwinner. The design of it seems to be a mixture of sun3i, sun4i and sun6i.
