From d369d92fc7ed2970540235b27441f75a81ef171b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 10 Mar 2020 15:46:49 +0100 Subject: bcm47xx: add support for kernel 5.4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ethernet, switch, LEDs, buttons, USB, sysupgrade & LuCI were successfully tested on BCM4706. WARNING: Hack for BCM4710 adding BCM4710_PROTECTED_FILL_TLB() to the local_r4k_flush_cache_sigtramp() could not be ported. That function has been dropped in: commit adcc81f148d7 ("MIPS: math-emu: Write-protect delay slot emulation pages") commit 3315b6b336c8 ("MIPS: Delete unused flush_cache_sigtramp()") it's unsure if that chipset will still work reliably.
