From 13581a5fa7ed09aa04393d496f44d0bf068e3024 Mon Sep 17 00:00:00 2001 From: Tomasz Maciej Nowak Date: Thu, 17 Dec 2020 17:24:27 +0100 Subject: [PATCH] ath79: airtight c-75: use second flash chip The flash capacity is divided in two flash chips and currently only first is used. Increase available space for OpenWrt by additional 16 MiB using mtd-concat driver. Because U-Boot might not be able to load kernel image spanned through two flash chips, the size of kernel is limited to space available on first first chip.
