From 0a5466d8d53bc8045ff56ff76cc1880aa85761c2 Mon Sep 17 00:00:00 2001 From: "ustcymgu@gmail.com" Date: Sat, 19 Nov 2022 14:02:55 +0000 Subject: RISC-V 32-bit support Added 32-bit RISC-V support. I have managed to get 32-bit RISC-V No-MMU Linux running based on mainstream buildroot. It's nice to have uclibc support this 32-bit No-MMU target. There's no substantial code change except definations and config options.
